Trim Video Online: Keep Only the Scene You Need
For a dubbing exercise, a night with friends or a fandub, you almost never dub a whole video: you pick a scene of 30 seconds to 2 minutes. A short clip makes everything easier: transcription is faster, adjusting the timings is simpler, and everyone can do several takes.
This tool will trim an MP4 or MOV video between a start and an end point you choose while watching it. The cut is accurate to the frame: the video is re-encoded from the exact point you pick, and the audio is aligned at the same time, so picture and voices stay in sync.
Your video never leaves your device: it is processed right in your browser, with no upload and no sign-up.
Your file never leaves your device: everything is processed in your browser.

Need a rythmo band?
BandeRythmo transcribes the dialogue and generates a rythmo band, a scrolling dubbing script synced to your video. The Studio is there if you then want to record your own voice, solo or with others.

How precise is the cut?
Frame-accurate: the video is re-encoded from the point you choose, instead of snapping to the nearest keyframe.
Does the audio stay in sync?
Yes. The audio track is cut over the same range and aligned to the start of the clip, without re-encoding.
How long should a clip be for dubbing?
Start with 30 seconds to 2 minutes. For anything longer, split the scene into several loops.
