Re: Videos - do we need both captions and transcripts?

Going by this, we DO need transcripts for all audio video content, right?

Thanks,

It's generally expected that people requiring captions aren't hearing
audio content, but are seing visual content.

Therefore, transcript is specified to support those who neither see nor
hear:

Hello All,
I have a super elementary question, what is the difference between prerecorded and synchronized video?  From what I can gather, it seems there is a level of interaction with synchronized video, like online tutorials or eLearning. Am I close?
Transcript are for prerecorded (according to this Section 508 checklist item 2.2<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.hhs.gov_web_section-2D508_making-2Dfiles-2Daccessible_checklist_html_index.html-3Flanguage-3Des&d=CwIBAw&c=yHlS04HhBraes5BQ9ueu5zKhE7rtNXt_d012z2PA6ws&r=8bgih609kFGNd3KTkZvS4SD8-_hY6QELODIGc63wIuE&m=uPDIur_EoYK7Iw8mT-FYh7DSzJhX4R9KHvIkQZdqkho&s=c8imw3CZmw7WrZWTSwzLD855OszQZMMg0s5Q7PGxQNw&e= >) and captions are for synchronized (checklist item 2.3).
If this is irrelevant and you advise using captions for all video content (except for a silent movie, of course) or if we need both captions and transcripts?
Thank you again for all your advice.
Thanks,
