IE 11 Accessible Video Features
IE also allows the user to adjust the playback speed to make it easier to read the captions, understand the context of the video or increase comprehension. It has more keyboard shortcut options and buttons accessible by the tab key.
There are some drawbacks to IE 11 when it comes to HTML5 videos. It has issues with captions that are in a VTT file. However it does support VTT, metadata headers.
It does fully support Timed Text Markup Language (TTML) without issue. It also doesn’t support descriptions, but that seems to be an issue with all the other browsers as well.
All browsers seem to have issues with screen readers. The controls disappear after the video playback begins so the person can’t stop the video.
