Interesting! At $0.02 to $0.04 an hour I don't suspect you've been hunting for optimizations, but I wonder if this "speed up the audio" trick would save you even more.

Doesn't YouTube do this for you automatically these days within a day or so?

Oh yeah, we do a check first and use youtube-transcript-api if there's an automatic one available:

https://github.com/jdepoix/youtube-transcript-api

The tool usually detects them within like ~5 mins of being uploaded though, so usually none are available yet. Then it'll send the summaries to our internal Slack channel for our editors, in case there's anything interesting to 'follow up on' from the meeting.

Probably would be a good idea to add a delay to it and wait for the automatic ones though :)

At this point you'll need to at least check how much running ffmpeg costs. Probably less than $0.01 per hour of audio (approximate savings) but still.

Last time I checked, I think the Google auto-captions were noticeably worse quality than whisper, but maybe that has changed.
