IMPORTANT NOTIFICATION:

The RWS AppStore > Wiki is no longer being maintained. For the latest updates and changes being published, please visit the official RWS AppStore, where you will find supporting information such as documentation & change log details that is associated to each app.

Alternatively if you are using Trados Studio 2022 SR2, you will find the same information within the Integrated AppStore.

Overview

Studio Subtitling is plugin for Trados Studio 2019-SR2 and Trados Studio 2021 that provides features for previewing subtitle captions within the video while translating segments in the Editor. This includes a verification provider with specific QA checks for validating subtitle content, ensuring the translations provided adhere to the standards agreed upon.

As we move forward, we will start to extend our portfolio in supporting additional subtitle formats.

The current release includes file type support for (SubStation Alpha) .ass (SubRip).srt, (WebVTT).vtt,(YouTube).sbv and (Spruce Subtitle file).stl formats.

Trados Studio 2019 SR2+ and Trados Studio 2021 support the following formats ‘out of the box’-.srt .vtt .sbv and .sub.

There may however be certain scenarios, where you are advised to install the separate plugin for a better experience.

If you are working with .stl, and /or .ass/ssa file types, you will need to install the relevant plugin.

In addition, we also released a new TQA model generated from the FAR model, covering the primary requirements in a providing a functional approach to assessing quality for subtitle formats, using the integrated Translation Quality Assessment feature of Studio.

Technical Requirements

We recommend Windows 8.1 (preferably W10) and SDL Trados Studio 2019 SR2 as a minimum.

Setup

Studio Subtitling Plugin

Download the Studio Subtitling plugin to your local drive
Double click on the plugin to launch the Plugin Installer and complete the installation, selecting the supported versions of Trados Studio.

File Type Plugins

Download the required File Type plugins to your local drive

Double click on each of the plugins to launch the Plugin Installer and complete the installation, selecting the supported versions of SDL Studio.

Complete the installation of the File types from within the Studio Options

Launch Studio 2021 (or 2019)
Select: File → Options → File Types
Click on the 'Additional installed File Types exist' link
Check the checkboxs associated with each of the File Types that you want installed from the Add Additional Installed File Types dialog
Click OK to save the settings

Subtitling Preview & Data controls

The Subtitling preview and data controls are available for valid subtitle documents. The Preview control provides a real-time preview of the subtitles within the video, whereas the Data control displays the subtitle metadata for each of the segments, along with real time verification feedback as the linguist is providing translations in the editor.

Configuration

Both the preview and data controls can be displayed and positioned anywhere within the Editor view.
To display the preview or data control:

Open a subtitle document in the Editor
Select the Ribbon view
Select the option Subtitling Preview or Subtitling Data from the ‘Information’ group
Reposition the control, docking or pinning it in the preferred location.

Features

Synchronized selection and content changes

The selected segment from the editor is synchronized with the subtitle track that is displayed in the video. When the user moves to a new segment in the editor, the corresponding track is selected in the video and similarly when the user selects a subtitle track in the video, focus is moved to the corresponding segment in the editor.
Additionally, changes applied to the translation are immediately visible in the subtitle caption from the video, including any formatting that was applied (e.g. bold, italic, underline…).

Real time verification feedback

Displays real time verification feedback as the content is being updated, providing the linguist with a much more informed approach in making decisions as they are translating.

Splitting & Merging segments

Support for splitting and merging segments within and across paragraph boundaries. When merging across paragraphs, all context and structure related to the paragraphs that have been fully merged to the parent paragraph are excluded from the native file that is regenerated with the target content.

Merged and Virtually merged files

Support for working with both merged and virtually merged files. Ideally each subtitle file that is added to the project should have a corresponding video reference with the same name (with exception to the file extension). Each time the user navigates to a new file within the document, the relative video is loaded (if available) and corresponding track in the video is selected.

Editable time tracks

Support for updating the display time of the subtitle captions. This feature permits a linguist to adapt the Start and End time-codes to align better with the translated content. This also includes hotkeys to automatically set the Start/End times from the current position of the video.

Time-code Format

Support for converting and displaying the time-code format between Frames and Milliseconds.

Setting a minimum time span between subtitles

Support for applying the rules of a styleguide to set a minimum time span between subtitles.

Keyboard Shortcuts

Support for assigning keyboard shortcuts to help automate interaction with the subtitling controls from the editor (e.g. jump back/forward from the video in seconds or frames, link/unlink the video, play back from previous subtitle etc...)

Usage

Pre-requisite

Install the Studio Subtitling and File Types plugins, following the steps listed in Setup.

Add a video reference

Launch the project wizard.
Add a subtitle document that is supported by one of the File Types installed.
Decide whether you want to add a video reference for the subtitle document during project creation or at a later stage from the Editor.
1. Add a video reference during project creation
  1. The file name of the video should match that of the subtitle document, with exception to the extension.
  2. The video will be a physical resource in the project, meaning that it will be included in the package. Keep this mind as video files can be quite large in size.
2. Don't add a video reference during project creation
  1. The video reference can be added at a later stage when the document is opened in the Editor.
  2. This option is more appropriate for distribution, keeping the overall size of the project small, while still allowing the linguist to download and add a reference later if required.
Click on Finish to complete the project creation.
Open the subtitle document for translation in the Editor.
1. If the Subtitling Preview or Subtitling Data controls are not visible in the Editor, then follow the steps listed in the Configuration.
2. If a video reference was not provided during the project creation, then a default image will be displayed in it's place. To load a video reference that coincides with the subtitles in the document, browse and select the media from the settings window of the plugin.
Once the video reference is loaded, the video will be displayed and subtitles will synchronize with the segments in the document.

Note: The area of the video in the Subtitling Preview control will adapt automatically to the aspect ratio of the video

Options

Go to the Subtitling Preview control.
Click on Settings to customize.
1. Video
  1. Video path
  2. Time-code format (Milliseconds or Frames)
  3. Frame Rate
2. Subtitle
  1. Font, color, wight, and size.
  2. Background color and opacity.
  3. Character edge color and style.

These will be your default captions format settings until you change them again or click Reset to go back to the default captions format.

Time-code format

The time-code format is always displayed in milliseconds from the Subtitle Preview control. It is read as milliseconds, unless the subtitle document has information to suggest otherwise. In the case that the format should be read as Frames, select the option 'Frames' from Time-code combobox in the Subtitle Preview Options dialog.

To successfully switch the Time-code format from Milliseconds to Frames:

The frame rate of the video must be known.
The fractional seconds (to be identified as frames) cannot exceed the frame rate for any of the time code entries for each of the segments in the document.
Make reference to Time-code Conversion to understand more.

Time-code Conversion

How to calculate the position in milliseconds, given the frame rate and frame:

Milliseconds Per Frame = 1000 / Frame Rate
Frames To Milliseconds = Frame * Milliseconds Per Frame

Given:
- Frame Rate = 24
- Frame = 4

Result:
  Milliseconds Per Frame = 41.666 (1000 / Frame Rate)
  Frame To Milliseconds = 166.666 (Frame * Milliseconds Per Frame)

How to calculate the position in frames, given the frame rate and milliseconds

Milliseconds Per Frame = 1000 / Frame Rate
Milliseconds To Frame = Milliseconds / Milliseconds Per Frame


Given:
- Frame Rate = 24
- Milliseconds = 166.666

 Result:
  Milliseconds Per Frame = 41.666 (1000 / Frame Rate)
  Milliseconds To Frame = 4  (Milliseconds / Milliseconds Per Frame)

Valid Subtitle Document

Any document whose paragraphs have a context of type=sdl:section, code=sec, and obtain a meta data entry with a key named timeStamp , whose value conforms to the following time span format

Time span format: hh:mm:ss[.fffffff]

"hh"	The number of hours in the time interval, ranging from 0 to 23.
"mm"	The number of minutes in the time interval, ranging from 0 to 59.
"ss"	The number of seconds in the time interval, ranging from 0 to 59.
"fffffff"	Fractional seconds in the time interval. This element is omitted if the time interval does not include fractional seconds. If present, fractional seconds are always expressed using seven decimal digits.

Verification Settings

We have integrated a specific set of verification checks for working with Subtitle documents. You can specify these verification settings for your project, along with the existing verification tools (e.g. QA Checker 3.0, Tag Verifier and Terminology Verifier)

Procedure

Go to the Projects view and select the project.
Go to the Home tab, and select Project Settings from the Ribbon.
Select: Verification → Studio Subtitling → Verification Settings
Configure other project settings if necessary and select OK.

QA Checks

CPS Number of characters per second	The number of characters per second Default settings: Report when less than: 12 (warning) Report when greater than: 15 (warning) Calculation: Total Seconds = (End time - Start time) → Seconds Characters Per Second = Total Characters / Total Seconds
WPM Number of words per minute	Based on the recommended rate of 160-180 words per minute, you should aim to leave a subtitle on screen for a minimum period of around 3 words per second or 0.3 seconds per word (e.g. 1.2 seconds for a 4-word subtitle). However, timings are ultimately an editorial decision that depends on other considerations, such as the speed of speech, text editing and shot synchronization. Default settings: Report when less than: 160 (warning) Report when greater than: 180 (warning) Calculation: Total Seconds = (End time - Start time) → Seconds Words Per Second = Words / Total Seconds Words Per Minute = Words Per Second * 60
CPL Number of characters per line	The number of characters per line Default settings: Report when greater than: 39 (warning) Method: Returns the total number of characters for each line in the subtitle caption. Report when any of the lines contain a number of characters greater than CPL setting assigned by the user.
LPS Number of lines per subtitle	A maximum subtitle length of two lines is recommended. Anything greater than that should be used if the linguist is confident that no important picture information will be obscured. When deciding between one long line or two short ones, consider line breaks, number of words, pace of speech and the image. Default settings: Report when greater than: 2 (warning)

Character Count

Spaces and punctuation are counted in all character counts

TQA

TQA can be seen as a functional approach to measuring quality in the translated content and from that assessment, evaluate and improve the process. We are introducing a new TQA model generated from the FAR model, covering the primary requirements in a providing a functional approach to assessing quality for subtitle formats, using the integrated Translation Quality Assessment feature of Studio.

FAR Model

Functional equivalence	*	F	Do the subtitles convey speaker meaning?	How well the message or meaning is rendered in the subtitled translation.
	Semantic errors	SE	The definition of a standard semantic equivalence error would be a subtitle that contains errors, but still has bearing on the actual meaning and does not seriously hamper the viewers’ progress beyond that single subtitle. Standard semantic errors would also be cases where utterances that are important to the plot are left unsubtitled. A serious semantic equivalence error scores 2 penalty points and is defined as a subtitle that is so erroneous that it makes the viewers’ understanding of the subtitle nil and would hamper the viewers’ progress beyond that subtitle, either by leading to plot misunderstandings or by being so serious as to disturb the contract of illusion for more than just one subtitle.	Minor functional equivalence errors are basically lexical errors, including terminology errors which do not affect the plot of the film.
	Stylistic errors	ST	Stylistic errors are not as serious as semantic errors, as they cause nuisance, rather than misunderstandings. Examples of stylistic errors would be erroneous terms of address, using the wrong register (too high or too low) or any other use of language that is out of tune with the style of the original (e.g. using modern language in historic films).
Acceptability	*	A	Do the subtitles sound correct and natural in the target language?	How well the subtitles adhere to target language norms.
	Grammar errors	GR	These are simply errors of target language grammar in various forms. A serious grammar error makes the subtitle hard to read and/or comprehend. Minor errors are the pet peeves that annoy purists (e.g. misusing ‘whom’ in English). Standard errors fall in between.
	Idiomaticity errors	ID	Errors that fall into this category are not grammar errors, but errors which sound unnatural in the target language. It should be pointed out that sometimes source text interference can become so serious that it becomes an equivalence issue
	Spelling errors	SP	Spelling errors could be judged according to gravity in the following way: A minor error is any spelling error. Standard errors change the meaning of the word. Serious errors would make a word impossible to read.
Readability	*	R	Can the subtitles be read in a fluent and non-intrusive way?	How easy the subtitles are for the viewer to process.
	Punctuation and graphics	PG	"Eats, shoots and leaves"
	Reading speed and line length	RS	Consider penalizing anything over 15 cps and up to 20 cps as a standard error. Above that is serious as you wouldn't have time to do anything apart from read the subtitles, and possibly not even finish that.	Measured in cps (characters per second)
	Segmentation and spotting	SS	Spotting errors are caused by bad synchronization with speech, (subtitles appear too soon or disappear later than the permitted lag on out-times) or image (subtitles do not respect hard cuts). Segmentation errors are when the semantic or syntactic structure of the message is not respected.	A serious spotting error would be when subtitles are out of sync by more than one utterance. A minor spotting error would be less than a second off, and a standard error in between these two extremes.

Subtitle File Type Support

Name	Extension	Default time-code format
SubRip *.srt	srt	Milliseconds
WebVTT *.vtt	vtt	Milliseconds
YouTube *.sbv	sbv	Milliseconds
Spruce Subtitle *.stl	stl	Frames
Advanced Substation Alpha *.ass	ssa/ass	Centiseconds (interpreted as Milliseconds)

FAQ

Q. Can I edit the Start and/or End time-codes of the subtitle from the Subtitling Data control?
A. Yes, editing the time-codes of the subtitle is fully supported. This feature permits a linguist to adapt the Start and End times to align better with the translated content.

Q. How does the plugin recognize which time-code format (i.e. milliseconds vs frames) to use?
A. The time-code format is read as milliseconds, unless the subtitle document has information to suggest otherwise. In the case that the format should be read as Frames, select the option 'Frames' from Time-code combobox in the Subtitle Preview Options dialog. Please refer to Time-code Format for more information.

Q. Can I add a new subtitle record or remove an existing one from the list of subtitles visible from the Studio Data Control?
A. This is currently not supported, as It would introduce a requirement to manage a structural change to the paragraphs of the document that would then need to be reflected when regenerating the native format.

Q. I would like to add a verification check that is specific to subtitling other than those included with the Studio Subtitling plugin, how can I do that?
A. Check if what you are looking for is not already included as a standard QA check with the other tools (e.g. QA Checker 3.0, Tag Verifier and Terminology Verifier). It is also possible to create/add your own, via the Regular Expressions area in the QA Checker tool. In addition, please take the opportunity to communicate any improvements of this nature to the AppStore team, as we welcome any suggestions/feedback from the community in area's where we can improve the features for future releases.

Q. I don't have a video reference for the subtitle document that I'm working on; will the verification checks still work?
A. Yes, the QA checks will still function correctly without a video reference, if you are working with a document that is recognized correctly by the File Types we have released to support subtitle formats

Q. Can I update the video reference after the project has been created?
A. The video reference can be associated with the subtitle document during project creation or linked to the active document from the editor at a later time. Any updates to the video reference path from the editor are persisted in the project file without affecting the project resources.

Time-code Conversion

How to calculate the position in milliseconds, given the frame rate and frame:

Milliseconds Per Frame = 1000 / Frame Rate
Frames To Milliseconds = Frame * Milliseconds Per Frame

Given:
- Frame Rate = 24
- Frame = 4

Result:
  Milliseconds Per Frame = 41.666 (1000 / Frame Rate)
  Frame To Milliseconds = 166.666 (Frame * Milliseconds Per Frame)

How to calculate the position in frames, given the frame rate and milliseconds

Milliseconds Per Frame = 1000 / Frame Rate
Milliseconds To Frame = Milliseconds / Milliseconds Per Frame


Given:
- Frame Rate = 24
- Milliseconds = 166.666

 Result:
  Milliseconds Per Frame = 41.666 (1000 / Frame Rate)

Launch the project wizard.
Add a subtitle document that is supported by one of the File Types installed.
Decide whether you want to add a video reference for the subtitle document during project creation or at a later stage from the Editor.
1. Add a video reference during project creation
  1. The file name of the video should match that of the subtitle document, with exception to the extension.
  2. The video will be a physical resource in the project, meaning that it will be included in the package. Keep this mind as video files can be quite large in size.
2. Don't add a video reference during project creation
  1. The video reference can be added at a later stage when the document is opened in the Editor.
  2. This option is more appropriate for distribution, keeping the overall size of the project small, while still allowing the linguist to download and add a reference later if required.
Click on Finish to complete the project creation.
Open the subtitle document for translation in the Editor.
1. If the Subtitling Preview or Subtitling Data controls are not visible in the Editor, then follow the steps listed in the Configuration.

Overview

Studio Subtitling is plugin for SDL Trados Studio 2019-SR2 and SDL Trados Studio 2021 that provides features for previewing subtitle captions within the video while translating segments in the Editor. This includes a verification provider with specific QA checks for validating subtitle content, ensuring the translations provided adhere to the standards agreed upon.

As we move forward, we will start to extend our portfolio in supporting additional subtitle formats.

The current release includes file type support for (SubStation Alpha) .ass (SubRip).srt, (WebVTT).vtt,(YouTube).sbv and (Spruce Subtitle file).stl formats.

SDL Trados Studio 2019 SR2+ and SDL Trados Studio 2021 support the following formats ‘out of the box’-.srt .vtt .sbv and .sub.

Keyboard Shortcuts

Usage

Pre-requisite

Install the Studio Subtitling and File Types plugins, following the steps listed in Setup.

Add a video reference

Launch the project wizard.
Add a subtitle document that is supported by one of the File Types installed.
Decide whether you want to add a video reference for the subtitle document during project creation or at a later stage from the Editor.
1. Add a video reference during project creation
  1. The file name of the video should match that of the subtitle document, with exception to the extension.
  2. The video will be a physical resource in the project, meaning that it will be included in the package. Keep this mind as video files can be quite large in size.
2. Don't add a video reference during project creation
  1. The video reference can be added at a later stage when the document is opened in the Editor.
  2. This option is more appropriate for distribution, keeping the overall size of the project small, while still allowing the linguist to download and add a reference later if required.
Click on Finish to complete the project creation.
Open the subtitle document for translation in the Editor.
1. If the Subtitling Preview or Subtitling Data controls are not visible in the Editor, then follow the steps listed in the Configuration.
2. If a video reference was not provided during the project creation, then a default image will be displayed in it's place. To load a video reference that coincides with the subtitles in the document, browse and select the media from the settings window of the plugin.
Once the video reference is loaded, the video will be displayed and subtitles will synchronize with the segments in the document.

Note: The area of the video in the Subtitling Preview control will adapt automatically to the aspect ratio of the video

Options

Go to the Subtitling Preview control.
Click on Settings to customize.
1. Video
  1. Video path
  2. Time-code format (Milliseconds or Frames)
  3. Frame Rate
2. Subtitle
  1. Font, color, wight, and size.
  2. Background color and opacity.
  3. Character edge color and style.

These will be your default captions format settings until you change them again or click Reset to go back to the default captions format.

Time-code format

To successfully switch the Time-code format from Milliseconds to Frames:

The frame rate of the video must be known.
The fractional seconds (to be identified as frames) cannot exceed the frame rate for any of the time code entries for each of the segments in the document.
Make reference to Time-code Conversion to understand more.

Time-code Conversion

How to calculate the position in milliseconds, given the frame rate and frame:

Milliseconds Per Frame = 1000 / Frame Rate
Frames To Milliseconds = Frame * Milliseconds Per Frame

Given:
- Frame Rate = 24
- Frame = 4

Result:
  Milliseconds Per Frame = 41.666 (1000 / Frame Rate)
  Frame To Milliseconds = 166.666 (Frame * Milliseconds Per Frame)

How to calculate the position in frames, given the frame rate and milliseconds

Milliseconds Per Frame = 1000 / Frame Rate
Milliseconds To Frame = Milliseconds / Milliseconds Per Frame


Given:
- Frame Rate = 24
- Milliseconds = 166.666

 Result:
  Milliseconds Per Frame = 41.666 (1000 / Frame Rate)
  Milliseconds To Frame = 4  (Milliseconds / Milliseconds Per Frame)

Valid Subtitle Document

Time span format: hh:mm:ss[.fffffff]

"hh"	The number of hours in the time interval, ranging from 0 to 23.
"mm"	The number of minutes in the time interval, ranging from 0 to 59.
"ss"	The number of seconds in the time interval, ranging from 0 to 59.
"fffffff"	Fractional seconds in the time interval. This element is omitted if the time interval does not include fractional seconds. If present, fractional seconds are always expressed using seven decimal digits.

Overview

Studio Subtitling is plugin for SDL Trados Studio 2019 that provides features for previewing subtitle captions within the video while translating segments in the Editor. This includes a verification provider with specific QA checks for validating subtitle content, ensuring the translations provided adhere to the standards agreed upon.

As we move forward, we will start to extend our portfolio in supporting additional subtitle formats. The initial release will include file type support for (SubRip).srt, (WebVTT).vtt,(YouTube).sbv and (Spruce Subtitle file).stl formats.

In addition, we are releasing a new TQA model generated from the FAR model, covering the primary requirements in a providing a functional approach to assessing quality for subtitle formats, using the integrated Translation Quality Assessment feature of Studio.

Revision 46 posted to Wiki by Paul Filkin on 8/21/2019 4:20:00 PM

Overview

Technical Requirements

Windows 8 and SDL Trados Studio 2019 are required as a minimum. The preview will not work at all with Windows 7 or earlier.

Setup

Studio Subtitling Plugin

Download the Studio Subtitling plugin to your local drive
Double click on the plugin to launch the SDL Plugin Installer and complete the installation, selecting the supported versions of SDL Studio.

File Type Plugins

Download the File Type plugins to your local drive.
Double click on each of the plugins to launch the SDL Plugin Installer and complete the installation, selecting the supported versions of SDL Studio.

Complete the installation of the File types from within the Studio Options

Launch Studio 2019
Select: File → Options → File Types
Click on the 'Additional installed File Types exist' link
Check the checkboxs associated with each of the File Types that you want installed from the Add Additional Installed File Types dialog
Click OK to save the settings.

Subtitling Preview & Data controls

Configuration

Both the preview and data controls can be displayed and positioned anywhere within the Editor view.
To display the preview or data control:

Open a subtitle document in the Editor
Select the Ribbon view
Select the option Subtitling Preview or Subtitling Data from the ‘Information’ group
Reposition the control, docking or pinning it in the preferred location.

Features

Synchronized selection and content changes

Real time verification feedback

Displays real time verification feedback as the content is being updated, providing the linguist with a much more informed approach in making decisions as they are translating.

Splitting & Merging segments

Merged and Virtually merged files

Editable time tracks

Time-code Format

Support for converting and displaying the time-code format between Frames and Milliseconds.

Keyboard Shortcuts

Usage

Pre-requisite

Install the Studio Subtitling and File Types plugins, following the steps listed in Setup.

Add a video reference

Launch the project wizard.
Add a subtitle document that is supported by one of the File Types installed.
Decide whether you want to add a video reference for the subtitle document during project creation or at a later stage from the Editor.
1. Add a video reference during project creation
  1. The file name of the video should match that of the subtitle document, with exception to the extension.
  2. The video will be a physical resource in the project, meaning that it will be included in the package. Keep this mind as video files can be quite large in size.
2. Don't add a video reference during project creation
  1. The video reference can be added at a later stage when the document is opened in the Editor.
  2. This option is more appropriate for distribution, keeping the overall size of the project small, while still allowing the linguist to download and add a reference later if required.
Click on Finish to complete the project creation.
Open the subtitle document for translation in the Editor.
1. If the Subtitling Preview or Subtitling Data controls are not visible in the Editor, then follow the steps listed in the Configuration.
2. If a video reference was not provided during the project creation, then a default image will be displayed in it's place. To load a video reference that coincides with the subtitles in the document, browse and select the media from the settings window of the plugin.
Once the video reference is loaded, the video will be displayed and subtitles will synchronize with the segments in the document.

Note: The area of the video in the Subtitling Preview control will adapt automatically to the aspect ratio of the video

Options

Go to the Subtitling Preview control.
Click on Settings to customize.
1. Video
  1. Video path
  2. Time-code format (Milliseconds or Frames)
  3. Frame Rate
2. Subtitle
  1. Font, color, wight, and size.
  2. Background color and opacity.
  3. Character edge color and style.

These will be your default captions format settings until you change them again or click Reset to go back to the default captions format.

Time-code format

To successfully switch the Time-code format from Milliseconds to Frames:

The frame rate of the video must be known.
The fractional seconds (to be identified as frames) cannot exceed the frame rate for any of the time code entries for each of the segments in the document.
Make reference to Time-code Conversion to understand more.

Time-code Conversion

How to calculate the position in milliseconds, given the frame rate and frame:

Milliseconds Per Frame = 1000 / Frame Rate
Frames To Milliseconds = Frame * Milliseconds Per Frame

Given:
- Frame Rate = 24
- Frame = 4

Result:
  Milliseconds Per Frame = 41.666 (1000 / Frame Rate)
  Frame To Milliseconds = 166.666 (Frame * Milliseconds Per Frame)

How to calculate the position in frames, given the frame rate and milliseconds

Milliseconds Per Frame = 1000 / Frame Rate
Milliseconds To Frame = Milliseconds / Milliseconds Per Frame


Given:
- Frame Rate = 24
- Milliseconds = 166.666

 Result:
  Milliseconds Per Frame = 41.666 (1000 / Frame Rate)
  Milliseconds To Frame = 4  (Milliseconds / Milliseconds Per Frame)

Valid Subtitle Document

Time span format: hh:mm:ss[.fffffff]

"hh"	The number of hours in the time interval, ranging from 0 to 23.
"mm"	The number of minutes in the time interval, ranging from 0 to 59.
"ss"	The number of seconds in the time interval, ranging from 0 to 59.
"fffffff"	Fractional seconds in the time interval. This element is omitted if the time interval does not include fractional seconds. If present, fractional seconds are always expressed using seven decimal digits.

Verification Settings

Procedure

Go to the Projects view and select the project.
Go to the Home tab, and select Project Settings from the Ribbon.
Select: Verification → Studio Subtitling → Verification Settings
Configure other project settings if necessary and select OK.

QA Checks

CPS Number of characters per second	The number of characters per second Default settings: Report when less than: 12 (warning) Report when greater than: 15 (warning) Calculation: Total Seconds = (End time - Start time) → Seconds Characters Per Second = Total Characters / Total Seconds
WPM Number of words per minute	Based on the recommended rate of 160-180 words per minute, you should aim to leave a subtitle on screen for a minimum period of around 3 words per second or 0.3 seconds per word (e.g. 1.2 seconds for a 4-word subtitle). However, timings are ultimately an editorial decision that depends on other considerations, such as the speed of speech, text editing and shot synchronization. Default settings: Report when less than: 160 (warning) Report when greater than: 180 (warning) Calculation: Total Seconds = (End time - Start time) → Seconds Words Per Second = Words / Total Seconds Words Per Minute = Words Per Second * 60
CPL Number of characters per line	The number of characters per line Default settings: Report when greater than: 39 (warning) Method: Returns the total number of characters for each line in the subtitle caption. Report when any of the lines contain a number of characters greater than CPL setting assigned by the user.
LPS Number of lines per subtitle	A maximum subtitle length of two lines is recommended. Anything greater than that should be used if the linguist is confident that no important picture information will be obscured. When deciding between one long line or two short ones, consider line breaks, number of words, pace of speech and the image. Default settings: Report when greater than: 2 (warning)

FAQ

Q. Can I edit the Start and/or End times of the subtitle captions from the Subtitling Data control?
A. Yes, editing the time track data of the subtitle is fully supported. This feature permits a linguist to adapt the Start and End times to align better with the translated content.

Q. Can I add a new cue or remove an existing one from the list of cues visible from the Studio Data Control?
A. This is currently not supported, as It would introduce a requirement to manage a structural change to the paragraphs of the document that would then need to be reflected when regenerating the native format.

Overview

Technical Requirements

Windows 8 and SDL Trados Studio 2019 are required as a minimum. The preview will not work at all with Windows 7 or earlier.

Setup

Studio Subtitling Plugin

Download the Studio Subtitling plugin to your local drive
Double click on the plugin to launch the SDL Plugin Installer and complete the installation, selecting the supported versions of SDL Studio.

File Type Plugins

Download the File Type plugins to your local drive.
Double click on each of the plugins to launch the SDL Plugin Installer and complete the installation, selecting the supported versions of SDL Studio.

Complete the installation of the File types from within the Studio Options

Launch Studio 2019
Select: File → Options → File Types
Click on the 'Additional installed File Types exist' link
Check the checkboxs associated with each of the File Types that you want installed from the Add Additional Installed File Types dialog
Click OK to save the settings.

Subtitling Preview & Data controls

Configuration

Both the preview and data controls can be displayed and positioned anywhere within the Editor view.
To display the preview or data control:

Open a subtitle document in the Editor
Select the Ribbon view
Select the option Subtitling Preview or Subtitling Data from the ‘Information’ group
Reposition the control, docking or pinning it in the preferred location.

Features

Synchronized selection and content changes

Real time verification feedback

Displays real time verification feedback as the content is being updated, providing the linguist with a much more informed approach in making decisions as they are translating.

Splitting & Merging segments

Merged and Virtually merged files

Editable time tracks

Time-code Format

Support for converting and displaying the time-code format between Frames and Milliseconds.

Keyboard Shortcuts

Usage

Pre-requisite

Install the Studio Subtitling and File Types plugins, following the steps listed in Setup.

Add a video reference

Launch the project wizard.
Add a subtitle document that is supported by one of the File Types installed.
Decide whether you want to add a video reference for the subtitle document during project creation or at a later stage from the Editor.
1. Add a video reference during project creation
  1. The file name of the video should match that of the subtitle document, with exception to the extension.
  2. The video will be a physical resource in the project, meaning that it will be included in the package. Keep this mind as video files can be quite large in size.
2. Don't add a video reference during project creation
  1. The video reference can be added at a later stage when the document is opened in the Editor.
  2. This option is more appropriate for distribution, keeping the overall size of the project small, while still allowing the linguist to download and add a reference later if required.
Click on Finish to complete the project creation.
Open the subtitle document for translation in the Editor.
1. If the Subtitling Preview or Subtitling Data controls are not visible in the Editor, then follow the steps listed in the Configuration.
2. If a video reference was not provided during the project creation, then a default image will be displayed in it's place. To load a video reference that coincides with the subtitles in the document, browse and select the media from the settings window of the plugin.
Once the video reference is loaded, the video will be displayed and subtitles will synchronize with the segments in the document.

Note: The area of the video in the Subtitling Preview control will adapt automatically to the aspect ratio of the video

Options

Go to the Subtitling Preview control.
Click on Settings to customize.
1. Video
  1. Video path
  2. Time-code format (Milliseconds or Frames)
  3. Frame Rate
2. Subtitle
  1. Font, color, wight, and size.
  2. Background color and opacity.
  3. Character edge color and style.

These will be your default captions format settings until you change them again or click Reset to go back to the default captions format.

Time-code format

To successfully switch the Time-code format from Milliseconds to Frames:

The frame rate of the video must be known.
The fractional seconds (to be identified as frames) cannot exceed the frame rate for any of the time code entries for each of the segments in the document.
Make reference to Time-code Conversion to understand more.

Time-code Conversion

How to calculate the position in milliseconds, given the frame rate and frame:

Milliseconds Per Frame = 1000 / Frame Rate
Frames To Milliseconds = Frame * Milliseconds Per Frame

Given:
- Frame Rate = 24
- Frame = 4

Result:
  Milliseconds Per Frame = 41.666 (1000 / Frame Rate)
  Frame To Milliseconds = 166.666 (Frame * Milliseconds Per Frame)

How to calculate the position in frames, given the frame rate and milliseconds

Milliseconds Per Frame = 1000 / Frame Rate
Milliseconds To Frame = Milliseconds / Milliseconds Per Frame


Given:
- Frame Rate = 24
- Milliseconds = 166.666

 Result:
  Milliseconds Per Frame = 41.666 (1000 / Frame Rate)
  Milliseconds To Frame = 4  (Milliseconds / Milliseconds Per Frame)

Valid Subtitle Document

Time span format: hh:mm:ss[.fffffff]

"hh"	The number of hours in the time interval, ranging from 0 to 23.
"mm"	The number of minutes in the time interval, ranging from 0 to 59.
"ss"	The number of seconds in the time interval, ranging from 0 to 59.
"fffffff"	Fractional seconds in the time interval. This element is omitted if the time interval does not include fractional seconds. If present, fractional seconds are always expressed using seven decimal digits.

Verification Settings

Procedure

Go to the Projects view and select the project.
Go to the Home tab, and select Project Settings from the Ribbon.
Select: Verification → Studio Subtitling → Verification Settings
Configure other project settings if necessary and select OK.

WPM Number of words per minute	Based on the recommended rate of 160-180 words per minute, you should aim to leave a subtitle on screen for a minimum period of around 3 words per second or 0.3 seconds per word (e.g. 1.2 seconds for a 4-word subtitle). However, timings are ultimately an editorial decision that depends on other considerations, such as the speed of speech, text editing and shot synchronization. Default settings: Report when less than: 160 (warning) Report when greater than: 180 (warning) Calculation: Total Seconds = (End time - Start time) → Seconds Words Per Second = Words / Total Seconds Words Per Minute = Words Per Second * 60
CPL Number of characters per line	The number of characters per line Default settings: Report when greater than: 39 (warning) Method: Returns the total number of characters for each line in the subtitle caption. Report when any of the lines contain a number of characters greater than CPL setting assigned by the user.
LPS Number of lines per subtitle	A maximum subtitle length of two lines is recommended. Anything greater than that should be used if the linguist is confident that no important picture information will be obscured. When deciding between one long line or two short ones, consider line breaks, number of words, pace of speech and the image. Default settings: Report when greater than: 2 (warning)

FAQ

Q. Can I edit the Start and/or End times of the subtitle captions from the Subtitling Data control?

A. Yes, editing the time track data of the subtitle is fully supported. This feature permits a linguist to adapt the Start and End times to align better with the translated content.

Q. How does the plugin recognize which time-code format (i.e. milliseconds vs frames) to use?

A. The time-code format is read as milliseconds, unless the subtitle document has information to suggest otherwise. In the case that the format should be read as Frames, select the option 'Frames' from Time-code combobox in the Subtitle Preview Options dialog. Please refer to Time-code Format for more information.

Q. Can I merged across paragraphs when working with the supported subtitle formats?

A. Merge across paragraphs is now fully supported with the latest release of the File Types (WebVTT, SBV, STL & ASS) version 1.0.3+ and Subtitling plugin version 1.0.8+. All context and structure related to the paragraphs that have been fully merged to the parent paragraph are excluded from the native file that is regenerated with the target content.
Unmerging segments is no longer supported from Studio 2019 SR1 CU3.

Q. I would like to add a verification check that is specific to subtitling other than those included with the Studio Subtitling plugin, how can I do that?

A. Check if what you are looking for is not already included as a standard QA check with the other tools (e.g. QA Checker 3.0, Tag Verifier and Terminology Verifier). It is also possible to create/add your own, via the Regular Expressions area in the QA Checker tool. In addition, please take the opportunity to communicate any improvements of this nature to the AppStore team, as we welcome any suggestions/feedback from the community in area's where we can improve the features for future releases.

Q. I don't have a video reference for the subtitle document that I'm working on; will the verification checks still work?

A. Yes, the QA checks will still function correctly without a video reference, if you are working with a document that is recognized correctly by the File Types we have released to support subtitle formats

Q. Can I update the video reference after the project has been created?

A. The video reference can be associated with the subtitle document during project creation or linked to the active document from the editor at a later time. Any updates to the video reference path from the editor are persisted in the project file without affecting the project resources.

Setup

Studio Subtitling Plugin

Download the Studio Subtitling plugin to your local drive
Double click on the plugin to launch the SDL Plugin Installer and complete the installation, selecting the supported versions of SDL Studio.

File Type Plugins

Download the File Type plugins to your local drive.
Double click on each of the plugins to launch the SDL Plugin Installer and complete the installation, selecting the supported versions of SDL Studio.

Complete the installation of the File types from within the Studio Options

Launch Studio 2019
Select: File → Options → File Types
Click on the 'Additional installed File Types exist' link
Check the checkboxs associated with each of the File Types that you want installed from the Add Additional Installed File Types dialog
Click OK to save the settings.

Subtitling Preview & Data controls

Configuration

Both the preview and data controls can be displayed and positioned anywhere within the Editor view.
To display the preview or data control:

Open a subtitle document in the Editor
Select the Ribbon view
Select the option Subtitling Preview or Subtitling Data from the ‘Information’ group
Reposition the control, docking or pinning it in the preferred location.

Features

Synchronized selection and content changes

The selected segment from the editor is synchronized with the subtitle track that is displayed in the video. When the user moves to a new segment in the editor, the corresponding track is selected in the video and similarly when the user selects a subtitle track in the video, focus is moved to the corresponding segment in the editor.
Additionally, all changes applied to the translation is immediately visible in the subtitle caption from the video, including any formatting that was applied (e.g. bold, italic, underline…).

Real time verification feedback

Displays real time verification feedback as the content is being updated, providing the linguist with much more informed approach in making decisions as they are translating.

Splitting & Merging segments

Merged and Virtually merged files

Editable time tracks

Support for updating the display time of the subtitle captions. This feature permits a linguist to adapt the Start and End time-span data to align better with the translated content.

Time-code Format

Support for converting and displaying the time-code format between the various standards (e.g. Milliseconds, Centiseconds & Frames)

Usage

Pre-requisite

Install the Studio Subtitling and File Types plugins, following the steps listed in Setup.

Add a video reference

Launch the project wizard.
Add a subtitle document that is supported by one of the File Types installed.
Decide whether you want to add a video reference for the subtitle document during project creation or at a later stage from the Editor.
1. Add a video reference during project creation
  1. The file name of the video should match that of the subtitle document, with exception to the extension.
  2. The video will be a physical resource in the project, meaning that it will be included in the package. Keep this mind as video files can be quite large in size.
2. Don't add a video reference during project creation
  1. The video reference can be added at a later stage when the document is opened in the Editor.
  2. This option is more appropriate for distribution, keeping the overall size of the project small, while still allowing the linguist to download and add a reference later if required.
Click on Finish to complete the project creation.
Open the subtitle document for translation in the Editor.
1. If the Subtitling Preview or Subtitling Data controls are not visible in the Editor, then follow the steps listed in the Configuration.
2. If a video reference was not provided during the project creation, then a default image will be displayed in it's place. To load a video reference that coincides with the subtitles in the document, browse and select the media from the settings window of the plugin.
Once the video reference is loaded, the video will be displayed and subtitles will synchronize with the segments in the document.

Note: The area of the video in the Subtitling Preview control will adapt automatically to the aspect ratio of the video

Options

Go to the Subtitling Preview control.
Click on Settings to customize.
1. Video
  1. Video path
  2. Time-code format (Milliseconds or Frames)
2. Subtitle
  1. Font, color, wight, and size.
  2. Background color and opacity.
  3. Character edge color and style.

These will be your default captions format settings until you change them again or click Reset to go back to the default captions format.

Time-code format

To successfully switch the Time-code format from Milliseconds to Frames:

The frame rate of the video must be known.
The fractional seconds (to be identified as frames) cannot exceed the frame rate for any of the time code entries for each of the segments in the document.
Make reference to Time-code Conversion to understand more.

Time-code Conversion

How to calculate the position in milliseconds, given the frame rate and frame:

Milliseconds Per Frame = 1000 / Frame Rate
Frames To Milliseconds = Frame * Milliseconds Per Frame

Given:
- Frame Rate = 24
- Frame = 4

Result:
  Milliseconds Per Frame = 41.666 (1000 / Frame Rate)
  Frame To Milliseconds = 166.666 (Frame * Milliseconds Per Frame)

How to calculate the position in frames, given the frame rate and milliseconds

Milliseconds Per Frame = 1000 / Frame Rate
Milliseconds To Frame = Milliseconds / Milliseconds Per Frame


Given:
- Frame Rate = 24
- Milliseconds = 166.666

 Result:
  Milliseconds Per Frame = 41.666 (1000 / Frame Rate)
  Milliseconds To Frame = 4  (Milliseconds / Milliseconds Per Frame)

Valid Subtitle Document

Time span format: hh:mm:ss[.fffffff]

"hh"	The number of hours in the time interval, ranging from 0 to 23.
"mm"	The number of minutes in the time interval, ranging from 0 to 59.
"ss"	The number of seconds in the time interval, ranging from 0 to 59.
"fffffff"	Fractional seconds in the time interval. This element is omitted if the time interval does not include fractional seconds. If present, fractional seconds are always expressed using seven decimal digits.

Verification Settings

Procedure

Go to the Projects view and select the project.
Go to the Home tab, and select Project Settings from the Ribbon.
Select: Verification → Studio Subtitling → Verification Settings
Configure other project settings if necessary and select OK.

QA Checks

CPS Number of characters per second	The number of characters per second Default settings: Report when less than: 12 (warning) Report when greater than: 15 (warning) Calculation: Total Seconds = (End time - Start time) → Seconds Characters Per Second = Total Characters / Total Seconds
WPM Number of words per minute	Based on the recommended rate of 160-180 words per minute, you should aim to leave a subtitle on screen for a minimum period of around 3 words per second or 0.3 seconds per word (e.g. 1.2 seconds for a 4-word subtitle). However, timings are ultimately an editorial decision that depends on other considerations, such as the speed of speech, text editing and shot synchronization. Default settings: Report when less than: 160 (warning) Report when greater than: 180 (warning) Calculation: Total Seconds = (End time - Start time) → Seconds Words Per Second = Words / Total Seconds Words Per Minute = Words Per Second * 60
CPL Number of characters per line	The number of characters per line Default settings: Report when greater than: 39 (warning) Method: Returns the total number of characters for each line in the subtitle caption. Report when any of the lines contain a number of characters greater than CPL setting assigned by the user.
LPS Number of lines per subtitle	A maximum subtitle length of two lines is recommended. Anything greater than that should be used if the linguist is confident that no important picture information will be obscured. When deciding between one long line or two short ones, consider line breaks, number of words, pace of speech and the image. Default settings: Report when greater than: 2 (warning)

Character Count

Spaces and punctuation are counted in all character counts

FAQ

Q. Can I merged across paragraphs when working with the supported subtitle formats?
A. Merge across paragraphs is now fully supported with the latest release of the File Types (WebVTT, SBV & STL) version 1.0.3+ and Subtitling plugin version 1.0.8+. All context and structure related to the paragraphs that have been fully merged to the parent paragraph are excluded from the native file that is regenerated with the target content.
The feature to merge across paragraphs in Studio is however limited, so far as there is no action to un-merge paragraphs after they have been merged, other than performing an undo operation in the editor. In the case where you perform an undo operation to un-merge merged paragraphs, then you will subsequently need to click on the Reload button from the Subtitling Preview control to refresh the data from both the Studio editor and Subtitling data-grids.

Q. Can I add a new cue or remove an existing one from the list of cues visible from the Studio Preview Control?
A. Currently this is not possible, but we might consider this feature in the future. It would introduce a structural change to the paragraphs of the document that would then need to be reflected when regenerating the native format.

Q. I don't have a video reference for the subtitle document that I'm working on; will the verification checks still work?
A. Yes, the QA checks will still function correctly if you are translating a document that is recognized correctly by the File Types we have released to support subtitle formats

FAQ

Q. Can I edit the Start and/or End time track data of the subtitle captions from the Studio Preview control?
A. Currently no, but the option might be considered with future releases. It is recommended that any errors related to the position and/or length of the subtitle track to be accessed and reported through TQA, understanding that these changes would also affect the source and most likely be applied by the author; eventually carried over to the target files.

Q. How does the plugin recognize which time-code format (i.e. milliseconds vs frames) to use?
A. The time-code format is always displayed in milliseconds from the Subtitle Preview control. It is read as milliseconds, unless the subtitle document has information to suggest otherwise. In the case that the format should be read as Frames, select the option 'Frames' from Time-code combobox in the Subtitle Preview Options dialog. Please refer to Time-code Format for more information.

Q. Can I add a new cue or remove an existing one from the list of cues visible from the Studio Preview Control?
A. Currently this is not possible as it would introduce a structural change to the paragraphs in the document, that would need to be reflected when regenerating the native format.

Subtitling Preview

The Subtitling Preview control is available for valid subtitle documents and provides a real-time preview of the subtitles within the video as the linguist is providing translations in the editor.

Configuration

The preview control can be displayed and positioned anywhere within the Editor view.
To display the preview control:

Open a subtitle document in the Editor
Select the Ribbon view
Select the option Subtitling Preview from the ‘Information’ group
Reposition the preview control, docking or pinning it in the preferred location.

Features

Synchronized selection

The selected segment from the editor is synchronized with the subtitle track that is displayed in the video. When the user moves to a new segment in the editor, the corresponding track is selected in the video and similarly when the user selects a subtitle track in the video, focus is moved to the corresponding segment in the editor.
Additionally, all changes applied to the translation is immediately visible in the subtitle caption from the video, including any formatting that was applied (e.g. bold, italic, underline…).

Splitting & Merging segments

Support for splitting and merging segments within and across paragraphs.

Merged and Virtually merged files

Usage

Pre-requisite

Install the Studio Subtitling and File Types plugins, following the steps listed in Setup.

Add a video reference

Launch the project wizard.
Add a subtitle document that is supported by one of the File Types installed.
Decide whether you want to add a video reference for the subtitle document during project creation or at a later stage from the Editor.
1. Add a video reference during project creation
  1. The file name of the video should match that of the subtitle document, with exception to the extension.
  2. The video will be a physical resource in the project, meaning that it will be included in the package. Keep this mind as video files can be quite large in size.
2. Don't add a video reference during project creation
  1. The video reference can be added at a later stage when the document is opened in the Editor.
  2. This option is more appropriate for distribution, keeping the overall size of the project small, while still allowing the linguist to download and add a reference later if required.
Click on Finish to complete the project creation.
Open the subtitle document for translation in the Editor.
1. If the Subtitling Preview view is not visible in the Editor, then follow the steps listed in Configuration.
2. if a video reference was not provided during project creation:
  1. You will be prompted to add a video reference once the document is loaded in the editor.
  2. Browse and load a video reference that coincides with to the subtitles in the document.
Once the video reference is loaded, the video will be displayed and subtitles will synchronize with the segments in the document.

  2. The video will be a physical resource in the project, meaning that it will be included in the package. Keep this mind as video files can be quite large in size.
2. Don't add a video reference during project creation
  1. The video reference can be added at a later stage when the document is opened in the Editor.
  2. This option is more appropriate for distribution, keeping the overall size of the project small, while still allowing the linguist to download and add a reference later if required.
Click on Finish to complete the project creation.
Open the subtitle document for translation in the Editor.
1. If the Subtitling Preview view is not visible in the Editor, then follow the steps listed in Configuration.
2. if a video reference was not provided during project creation:
  1. You will be prompted to add a video reference once the document is loaded in the editor.
  2. Browse and load a video reference that coincides with to the subtitles in the document.
Once the video reference is loaded, the video will be displayed and subtitles will synchronize with the segments in the document.

Note: The area of the video in the Subtitling Preview control will adapt automatically to the aspect ratio of the video

These will be your default captions format settings until you change them again or click Reset to go back to the default captions format.

Time-code format

To successfully switch the Time-code format from Milliseconds to Frames:

The frame rate of the video must be known.
The fractional seconds (to be identified as frames) cannot exceed the frame rate for any of the time code entries for each of the segments in the document.
Make reference to Time-code Conversion to understand more.

Time-code Conversion

How to calculate the position in milliseconds, given the frame rate and frame:

Milliseconds Per Frame = 1000 / Frame Rate
Frames To Milliseconds = Frame * Milliseconds Per Frame

Given:
- Frame Rate = 24
- Frame = 4

Result:
  Milliseconds Per Frame = 41.666 (1000 / Frame Rate)
  Frame To Milliseconds = 166.666 (Frame * Milliseconds Per Frame)

How to calculate the position in frames, given the frame rate and milliseconds

Milliseconds Per Frame = 1000 / Frame Rate
Milliseconds To Frame = Milliseconds / Milliseconds Per Frame


Given:
- Frame Rate = 24
- Milliseconds = 166.666

 Result:
  Milliseconds Per Frame = 41.666 (1000 / Frame Rate)
  Milliseconds To Frame = 4  (Milliseconds / Milliseconds Per Frame)

Valid Subtitle Document

Time span format: hh:mm:ss[.fffffff]

"hh"	The number of hours in the time interval, ranging from 0 to 23.
"mm"	The number of minutes in the time interval, ranging from 0 to 59.
"ss"	The number of seconds in the time interval, ranging from 0 to 59.
"fffffff"	Fractional seconds in the time interval. This element is omitted if the time interval does not include fractional seconds. If present, fractional seconds are always expressed using seven decimal digits.

Functional equivalence	*	F	Do the subtitles convey speaker meaning?	How well the message or meaning is rendered in the subtitled translation.
	Semantic errors	SE	The definition of a standard semantic equivalence error would be a subtitle that contains errors, but still has bearing on the actual meaning and does not seriously hamper the viewers’ progress beyond that single subtitle. Standard semantic errors would also be cases where utterances that are important to the plot are left unsubtitled. A serious semantic equivalence error scores 2 penalty points and is defined as a subtitle that is so erroneous that it makes the viewers’ understanding of the subtitle nil and would hamper the viewers’ progress beyond that subtitle, either by leading to plot misunderstandings or by being so serious as to disturb the contract of illusion for more than just one subtitle.	Minor functional equivalence errors are basically lexical errors, including terminology errors which do not affect the plot of the film.
	Stylistic errors	ST	Stylistic errors are not as serious as semantic errors, as they cause nuisance, rather than misunderstandings. Examples of stylistic errors would be erroneous terms of address, using the wrong register (too high or too low) or any other use of language that is out of tune with the style of the original (e.g. using modern language in historic films).
Acceptability	*	A	Do the subtitles sound correct and natural in the target language?	How well the subtitles adhere to target language norms.

	Segmentation and spotting	SS	Spotting errors are caused by bad synchronization with speech, (subtitles appear too soon or disappear later than the permitted lag on out-times) or image (subtitles do not respect hard cuts). Segmentation errors are when the semantic or syntactic structure of the message is not respected.	A serious spotting error would be when subtitles are out of sync by more than one utterance. A minor spotting error would be less than a second off, and a standard error in between these two extremes.

Overview

Setup

Studio Subtitling Plugin

Download the Studio Subtitling plugin to your local drive
Double click on the plugin to launch the SDL Plugin Installer and complete the installation, selecting the supported versions of SDL Studio.

File Type Plugins

Download the File Type plugins to your local drive.
Double click on each of the plugins to launch the SDL Plugin Installer and complete the installation, selecting the supported versions of SDL Studio.

Complete the installation of the File types from within the Studio Options

Launch Studio 2019
Select: File → Options → File Types
Click on the 'Additional installed File Types exist' link
Check the checkboxs associated with each of the File Types that you want installed from the Add Additional Installed File Types dialog
Click OK to save the settings.

Subtitling Preview

The Subtitling Preview control is available for valid subtitle documents and provides a real-time preview of the subtitles within the video as the linguist is providing translations in the editor.

Configuration

The preview control can be displayed and positioned anywhere within the Editor view.
To display the preview control:

Open a subtitle document in the Editor
Select the Ribbon view
Select the option Subtitling Preview from the ‘Information’ group
Reposition the preview control, docking or pinning it in the preferred location.

Features

Synchronized selection

The selected segment from the editor is synchronized with the subtitle track that is displayed in the video. When the user moves to a new segment in the editor, the corresponding track is selected in the video and similarly when the user selects a subtitle track in the video, focus is moved to the corresponding segment in the editor.
Additionally, all changes applied to the translation is immediately visible in the subtitle caption from the video, including any formatting that was applied (e.g. bold, italic, underline…).

Splitting & Merging segments

Support for splitting and merging segments within a paragraph, but not across paragraph boundaries to avoid a requirement in editing the time track information. It is recommended that any errors related to the position and/or length of the subtitle track to be accessed and reported through TQA, understanding that these changes would also affect the source and most likely be applied by the author; eventually carried over to the target files.

Merged and Virtually merged files

Usage
