Captions Controllable
Group: images-and-media • Guideline: captions
Summary in Plain English
There is a way to turn captions on and off, unless they are burned into the video.
Why It Matters
Captions cover part of the picture and are a distraction to viewers who do not need them, so the choice has to sit with the viewer.
