I would always fail captions without sufficient contrast to the background. I often see this when the captions are placed directly on the video image which makes them pretty much unusable. It is easy to use YouTube to change the contrast and have a background, so I don't find a reason for this. +1 to fail Please be advised that I check my emails at approximately 9am and 4pm each day (more or less). If you require assistance sooner, please feel free to telephone.

Why just advisory? Captions are clearly a form of text, and screenshots can provide clear evidence of failure. In audits I frequently see white caption text on transparent grey background which means contrast is FAR below 4.5:1 whenever the video background happens to be bright.

The author put it in an image because she wanted it in a special font, or a special position in relation to a background which might have been hard to do with CSS etc... This is not the case for a movie. Authors rarely make movies with the intention of achieving a particular text effect. > > > > > > I haven't been watching movies looking for colour contrast failures of significant text.
