there is a problem:
the transcripts / subtitles / captions are often lack of sufficient context. it could be very short, like 2 or 3 words, and you might not know what's that exactly.
So, saving only one sentence in transcript might not always be a good choice as my own opinion. That's one of the reason that i do not make the caption in youtube be selectable. and the second reason is that is troublesome 😥.
What I mean is, using the transcript function that built-in the youtube, you can get as much context as you want! (though it is not that easy to select 😅)
