> But since YouTube transcription is really good
Are you sure you're looking at automatic transcripts? YouTube transcripts are bizarrely low quality if they're not provided by the creators (I've actually used my Google Pixel's live transcription to make better captions occasionally).
I just checked a video my girlfriend uploaded a week ago and the auto-transcript was still pretty messy. I've used Whisper for the same task and it's significantly better.
That's crazy, months ago I compared whisper v2 transcripts with YouTube transcripts generated on my video and found them to be identical, down to the timestamps.
I know people who upload a video on YouTube unlisted just to get transcripts generation for free and then delete the video.
