For blind SR users I'd add as BEST PRACTICE:

Consider a text alternative with rich semantics (headings, lists, ...), not only a transcript. For instance, a ordered list describes step by step what has to be done.
This takes less time to perceive information, navigate between steps and copy text to edit.

And sometimes a description for an alternative way to perform the functionality with keyboard only might be a necessary nice to have:
Think of a video that shows where to click on the screen to print. The information should be provided that ctrl + p does the same.

And provide the corresponding heading information:
- Video transcript: Printing with a mouse click
- Printing with keyboard shortcuts

That's exactly what WCAG 1.2.1 is for (
https://www.w3.org/TR/WCAG21/#audio-only-and-video-only-prerecorded). I don't run across prerecorded video-only very often so it's nice to see an example here.

1.2.1 says, "Either an alternative for time-based media or an audio track is provided that presents equivalent information...". The "alternative" is typically a transcript, as Aditya mentioned, but you can also provide an audio track. Essentially an audio description. I wouldn't complain if you provided both (smile).
