Common questions
Processing speed depends on video length. A one-hour file typically yields a clip list in 4 to 6 minutes. Export rendering takes an additional 30 to 90 seconds per clip after you confirm selections.
We accept MP4, MOV, and WebM. Files can be up to 20GB and up to 4 hours in duration. If your file is larger, contact us and we can enable higher limits for your account.
Yes. Each clip candidate has a trim control to adjust in and out points. Caption text is also editable inline before burn-in, useful if the transcript misheard a word.
Yes. Podcasts, panel discussions, interviews, and webinar recordings all work well. Detection is based on audio energy and speaker dynamics, not streaming-specific signals.
