Thanks for the thread dude, it's really well done.
Clipping it now, hol up
Also just to answer this ^^^. The reason it tanks at ~3h40 is because there's some muted audio just before her ASMR segment starts, so when tools like untwitch try to pull the VOD's .m3u8 they get hit with a 403 error and just stop. You can use ffmpeg or equivalent to skip/ignore the muted chunks.
