I was trying to summarize a 40-minute talk with OpenAI’s transcription API, but it was too long. So I sped it up with ffmpeg to fit within the 25-minute cap. It worked quite well (Up to 3x speeds) and was cheaper and faster, so I wrote about it.

Felt like a fun trick worth sharing. There’s a full script and cost breakdown.

You could have kept quiet and started a cheaper than openai transcription business :)

I've already done that [1]. A fraction of the price, 24-hour limit per file, and speedup tricks like the OP's are welcome. :)

Pre-processing of the audio still a valid biz, multiple types of pre-processing might be valid

Sure, but now the world is a better place because he shared something useful!

Or openai will do it themselves for transcription tasks
