Accessibility

The “Accessibility” tab on a media clip is where you manage all language and accessibility-related assets: subtitles, transcripts, audio tracks, audio descriptions, and sign language videos. These assets work together with the corresponding settings in the “Accessibility” tab of your playout. Learn more about playout accessibility settings.

1.0 | Clip language

At the top of the tab you can set the primary language of the media clip. The OVP attempts to detect the clip language automatically from the file metadata, but you can override it here using the language dropdown.

This setting is used, among other things, as a reference language for transcription and subtitle translation.

2.0 | Subtitles and closed captions

Subtitles and closed captions both display audio content as text in the player. Subtitles transcribe dialogue (often in other languages) for viewers who can hear the audio. Closed captions are intended for viewers who cannot hear the audio at all, and therefore also include descriptions of relevant sounds (for example: [applause] or [music playing]).

Both are managed in the same way in the OVP and support the following file formats: .srt (SubRip) and .ttxt (Timed Text).

2.1 | Upload a subtitle file

If you already have an .srt or .ttxt file, created yourself or by a third-party service, upload it as follows:

1. Navigate to Media Clips
2. Open the relevant media clip
3. Browse to the “Accessibility” tab
4. Click “Upload subtitle” and select the file from your computer

After uploading, select the accompanying language and click “Save”.

2.2 | Create subtitles in the OVP Subtitle Editor

You can create a new subtitle file directly in the OVP using the built-in Subtitle Editor.

1. Navigate to Media Clips
2. Open the relevant media clip
3. Browse to the “Accessibility” tab
4. Click “Create subtitle”

5. Select a language
6. Enter your subtitles using the Subtitle Editor (see section 9.0)

2.3 | Edit, download, or delete subtitles

Any subtitle file, whether uploaded or created in the OVP, can be managed from the subtitles table:

• Click the pencil icon to edit a subtitle file in the Subtitle Editor (see section 9.0)
• Click the download icon to download the subtitle file
• Click the delete icon to remove the subtitle file

Each subtitle in the table also shows its publication status. Unpublished subtitles are not visible to viewers.

3.0 | Speech2Text: automatically generated subtitles

The Speech2Text feature (powered by Scriptix) automatically generates subtitles for a media clip based on its spoken audio content. It also supports generating subtitles in additional languages, making it possible to produce multilingual subtitles from a single clip.

To generate subtitles automatically:

1. Navigate to Media Clips
2. Open the relevant media clip
3. Browse to the “Accessibility” tab
4. In the Speech2Text section, select the transcription language
5. Optionally, enable “Include original language in output” to include subtitles in the clip’s primary language alongside any translations
6. Optionally, select one or more translation languages from the “Generate translations” dropdown; subtitles will be generated in each selected language
7. Click “Generate subtitles”

Generating subtitles may take a few minutes. Once complete, the generated subtitle file(s) appear in the subtitles table. Automatically generated subtitles should always be reviewed and corrected before publishing; use the Subtitle Editor for this (see section 9.0).

Subtitles are also automatically added to the page metadata as a transcript, which helps search engines better understand your video content.

4.0 | Transcripts

Transcripts use the same .srt or .ttxt file format as subtitles, but are displayed differently: rather than showing one line at a time in the player, the full text is displayed alongside the player in a separate element. As the video plays, the corresponding part of the transcript is highlighted. Viewers can also click on any phrase in the transcript to jump directly to that moment in the video.

Transcripts can be uploaded, created, and edited in the same way as subtitles. They appear in a separate “Transcripts” table in the “Accessibility” tab.

To upload a transcript:

1. Navigate to Media Clips
2. Open the relevant media clip
3. Browse to the “Accessibility” tab
4. Click “Upload transcript” and select your .srt or .ttxt file

To enable the transcript display for viewers, configure the corresponding settings in the “Accessibility” tab of your playout.

5.0 | Audio tracks

Audio tracks are alternative audio streams for the video; for example, a dubbed version in another language. Uploading an audio track makes it selectable in the player control bar, allowing viewers to switch between audio languages.

Supported file formats: audio files (such as .mp3, .aac, .wav) and video files (the audio stream is extracted).

To upload an audio track:

1. Navigate to Media Clips
2. Open the relevant media clip
3. Browse to the “Accessibility” tab
4. Click “Upload audio track” and select your file
5. Once uploaded, select the language and click “Save”

Each audio track in the table shows its publication status. Use the pencil icon to edit the language or status, the download icon to download the file, or the delete icon to remove it.

6.0 | Audio descriptions

Audio descriptions are a separate narration track that describes what is happening on screen, intended for viewers with visual impairments. They are uploaded and managed separately from regular audio tracks.

Supported file formats: audio files (such as .mp3, .aac, .wav) and video files.

To upload an audio description:

1. Navigate to Media Clips
2. Open the relevant media clip
3. Browse to the “Accessibility” tab
4. Click “Upload audio description” and select your file
5. Once uploaded, select the language and click “Save”

To show or hide the audio description button in the player control bar, configure the corresponding setting in the “Accessibility” tab of your playout.

7.0 | Sign language

Sign language assets are video files showing a sign language interpreter alongside the original video. The sign language video is uploaded as a companion clip linked to the original media clip.

Only video file formats are supported for sign language assets.

To upload a sign language asset:

1. Navigate to Media Clips
2. Open the relevant media clip
3. Browse to the “Accessibility” tab
4. Click “Upload sign language” and select your video file
5. Once uploaded, select the sign language variant and click “Save”

To show or hide the sign language button in the player control bar, configure the corresponding setting in the “Accessibility” tab of your playout.

8.0 | Scribit.pro: professional accessibility services

If your publication is configured with Scribit.pro, you can order professionally produced accessibility assets directly from the “Accessibility” tab using the “Make My Video Accessible” button. This connects you to a service where accessibility experts produce the following assets:

• Audio description: a narration track produced by a voice artist describing the visual content
• Subtitles: professionally transcribed and timed subtitle files
• Transcript: a full written transcript of the video

You can add remarks to provide context or specific instructions to the Scribit.pro team. A pricing overview is shown in the request modal before you submit.

Standard pricing: a fixed fee of €75 plus an additional fee of €45 per minute of video.

Urgent option: requests are handled within 24 hours at a fixed fee of €75 plus €65 per minute of video.

Jobs are typically completed within 3–5 business days.

Once complete, the generated assets appear automatically in the respective sections of the “Accessibility” tab.

9.0 | The Subtitle Editor

The Subtitle Editor is used to create or edit subtitle and transcript files. It offers two views:

1. The visual line editor: an intuitive interface with a live video preview
2. The raw .srt editor: direct editing of the file in .srt format

9.1 | Visual line editor

The visual line editor is the recommended approach. It provides a live preview of the video and makes it straightforward to align subtitle timing without needing to know the .srt format.

There are two ways to adjust the start and end time of a subtitle line:

1. Enter the timestamp directly:

2. Use the playback controls below the preview to set the start and end time interactively:

9.2 | Raw .srt editor

The raw .srt editor lets you edit the file content directly. The .srt format has strict syntax rules: numeric counters, timestamp notation, and line spacing must all be preserved exactly.

The sample code shown in the editor provides a formatting reference. You can also consult the .srt format specification.
