Subject: Video captioning when the video contains text on screen
No previous message | Next message →

Could you direct me to resources that could help me address the following situation?

We have a video that is mostly like a PowerPoint presentation that has most of the spoken content already on the screen. However, sometimes the speaker says some stuff slightly differently.

What are the captioning requirements and recommendations at a WCAG 2.0 AA level when the video has text on screen, but no caption file, and the spoken text is mostly, but not always the same as what is already on the screen?

Do we need to add a caption file or transcript to the video?
If we do caption it, do we just write out the spoken content, or do we also include the written content (even when spoken and on-screen content are already the same)?

Thanks,
Vanessa

Where I work, my lead can make authoritative decisions. He has interpreted
508 and WCAG 2.0 as "if the only thing said is what's on the screen, then
they can act as the captions. If the speaker goes off on a tangent or
expands upon a point, captions are required throughout the video." We
unofficially are fine if the speaker throws in a verb periodically to make
it a complete sentence.

Now this may not fly with everybody, but this is the position we adopted

As long as they are synchronized you have a case to argue. If you had a whole screen of text rather than a line or two at a time then it might be harder to argue that they are synchronized with other visuals going on. How far you could push having a large amount of text might be a discussion point.

I've also run into these situations where you have animations with audio and the text on-screen. People often ask if the audio is sufficient or if the images in the animations need to have alternatives. While non-text must have alternatives -- if the non-text content is part of time-based media it only needs a description as the audio or audio description in the time-based media can act as the media alternative. But certainly this is a fine line to walk when animations have stop and start buttons and it may be preferable for people who are Deafblind to read the text in Braille with their screen readers as audio and captions are likely not accessible to them (unless the captions are accessible non-embedded text and it is easier to step through them).
