How to use Trim video

Keep one selected time interval and re-encode it locally as supported WebM or MP4.

  1. Choose one local file or use the synthetic sample, then set the options. No reading or encoding starts until the action is chosen.
  2. One file ≤30 MiB / 60 seconds; one audio + one video track; mono/stereo 8–48 kHz; SDR video ≤1080p / 30 fps / 1,800 frames. Output ≤32 MiB. Native codecs vary.
  3. Keeps one interval. Endpoints are limited by output video/audio precision; this is a re-encode. Source metadata, chapters and original compression are discarded. Codecs must be available locally; no upload or server fallback. Re-encoding changes quality.
  4. Run locally and review the result. Downloaded files remain on your device. Edit, Clear or leaving discards the old result; Cancel terminates its worker. No file or result is uploaded or stored in your account.
