+1 to the .vtt format change. I had a stakeholder do this recently and try to upload a bunch of the .vtt formatted transcripts to ChatGPT. It couldn't read them properly and ended up hallucinating lots of quotes that ended up in their report ๐
I was able to catch that instance, but we have a lot of folks who'd prefer to pull their transcripts into multiple other tools. So I worry about this happening to others.
