With a RTX4090 and insanly-fast-whisper on whisper-large-v3-turbo (see Whisper-WebUI for easy testing) you can transscribe 5000h on consumer hardware in about 50h with timestamps.
So, yeah. I also know someone.
Grabbing the audio from thousands of hours of video, or even just managing getting the content from wherever it's stored, is probably more of an issue than actually creating the transcripts.
If anyone reading this has access to the original recordings, this is a pretty great time to get transcriptions.
