Video Merger

Put several clips end to end, in the order you added them.

Free video merger: combine several videos into one, in the order you add them. Merge MP4, MOV, MKV, VOB and TS clips. No watermark, nothing uploaded.

What Video Merger is for

Several clips that should be one: a recording split across files by the camera, a screen capture in parts, or an intro you want in front of the thing itself.

Joining clips from different sources

Clips can differ in resolution, frame rate and format; they are brought to a common format as they are joined. The result is MP4, WEBM or MKV, with the clips in the order you added them, so add them first to last.

DVD and camcorder files

A DVD title is split into VOB files of up to 1 GB each, and camcorders split long recordings into MTS files of about 2 GB. Add the consecutive pieces here to get one continuous video. Both are usually interlaced, so run the result through Restore Old Video.

Keeping it small

Merging several phone videos can produce a large file. Choose a lower quality here, or compress the result afterwards to fit an upload limit.

How to use it

  1. Add your files. Drop them on the page or choose them. They stay on your device.
  2. Set the output format and quality. The defaults suit most files.
  3. Press convert and save the results, individually or as one ZIP.

Questions

Does joining re-encode my videos?

Only if it has to. When every clip already shares a codec, size and frame rate, the streams are copied end to end with no quality loss at all and a dozen clips take about a second. Mixed sources have to be put on a common grid first, which does mean re-encoding, and that is slower.

What order do they join in?

The order you added them. Add them one at a time, or drop a selection in the order you want them to play.

Can I join clips of different sizes?

Yes. They are scaled onto the first clip’s frame size and given a common frame rate and sample rate, because a container cannot hold a track that changes shape halfway through. Mixing portrait and landscape works but will letterbox one of them.

Is there a limit on how many?

Only your device’s memory. The work happens in this tab, so a long list of large files is limited by the same thing that limits any other program on your machine.
