@sidereal I can't comment on the time taken to edit video.
As someone who occasionally transcribes: I assure readers that the time required to transcribe can be enormous — COLOSSAL — compared to the duration of the audio or AV content that must be listened to, repeatedly.
I can not speak for @howisyourdog but I typically don't bother with content that lacks captions (subtitles). Substandard accessibility is an immediate turn-off.
