Field notes

Users can choose a spoken language or auto-detect it, then review word-timed lines against the clip. The page identifies Whisper large-v3 turbo and says vertical video gets shorter lines—around 22 characters, compared with roughly 42 generally. It warns that proper names, heavy accents, simultaneous speakers, and numbers are recurring error cases, and says clicking a caption line jumps playback to that moment.
