Frequently asked questions
Can I auto-generate subtitles?
Yes. Speech-to-text creates captions from the audio, which you can then edit, re-time, and style.
Can I fix subtitle timing?
Yes. Shift the whole track, sync it to the audio, and edit individual cue times.
What does burn-in mean?
Burn-in draws the subtitles permanently onto the video frames, so they play anywhere — even on players that ignore caption files.
