[Athen] Checking for Captions

That’s correct. Burned in captions are like photos with text in them. A T can’t determine which pixels create text letters and which create the background graphic. Always best to keep text live, not “burned in” graphics or videos or any other form of graphical communication.

 

Machines like screen readers can only access and process live text.

Many video players do have accessible caption toggles and some make the text accessible to screen readers. But if a video has burned-in captions, there wouldn’t be a way for a screen reader user to detect those.

Subject: [Athen] Checking for Captions

 

Hello, is it possible for a blind person to check if there are captions in a video?  Everything I know tells me not, but I want to ask anyway in case there is some way that I am unaware of.  The captions are displayed in the actual video content, which is not readable by a screen reader.  I know on YouTube, I might be able to tell by whether the captions button is present or not, but I'm not sure if that button is always there or just when captions are available.  Even then, I don't think I would be able to evaluate the captions anyway.

 

Thanks,

Robert
