Common questions about Automatic Subtitle Generator
What is the difference between Timestamped Transcript and Subtitle Generator?
Subtitle Generator groups speech into subtitle-friendly cues. Timestamped Transcript is optimized for shorter creator/editing beats and adds CSV/JSON timeline exports.
Can it generate subtitles for multiple languages?
It can transcribe multilingual speech supported by Whisper; auto detection is the default.
Does it burn captions into the video?
No. V1 exports subtitle files; it does not render text permanently into video pixels.
