What potential accommodations can be included with video to ensure it is accessible to people with disabilities?

You can use close captions, never just auto-generated captions. Remember there must be more than one way to communicate what is happening can be actions that happen off-screen or in the background, if you are doubting if something was clear enough you can add descriptions on captions. If you show something on-screen, make sure to communicate it on audio, if the content is only audio, then create a transcript and synchronized captions.
