Merge Videos
Put clips end to end in one video. Recordings from the same camera or export are joined by copying them, with no quality loss at all; clips that differ are re-encoded to match the first one.

Frequently asked questions
Do the clips have to match?
No, but it helps. Clips with the same codec, size and sound settings — which is what one camera or one export gives you — are joined by copying, instantly and losslessly. Mixed clips are re-encoded to the first clip's picture size, and anything shaped differently is fitted inside with black bars rather than stretched.
Is my footage uploaded?
No. Everything happens in your browser, which is what makes joining several large clips practical at all.
What if one clip has no sound?
Silence fills its part, so everything after it stays in step — and the result tells you which clip it was. Without that, every tool that simply drops the gap leaves the rest of the video out of sync.
Can I add a crossfade or titles?
No. This joins clips cleanly at the cut; fades, titles and music belong in an editor. What it does do is give you one file, quickly, without a watermark or an account.
Is there a limit to how many clips?
Practically, no — they are streamed one after another rather than held in memory. Dozens of clips are fine; the only real limit is the free space on your device.
What if the clips have different frame rates?
They are joined on one clock, so a 60 fps clip after a 30 fps clip plays at the right speed. When re-encoding, the timing of every frame is preserved rather than resampled.
Good to know: Portrait and landscape clips in one video mean black bars on one of them — video files cannot change shape halfway through. Only the main video and sound track of each clip are used.
