Subtitle Generation FAQ

Can videos without captions get subtitles?

Yes, this is the core direction: get audio first, then generate subtitles from the audio instead of relying only on platform captions.

What is the difference between SRT, VTT and TXT?

TXT is best for reading and copying. SRT and VTT keep timestamps for editors and players.

Are generated subtitles always accurate?

Accuracy depends on audio quality, accents, background noise and overlapping speech. Manual review is recommended.
