How it works

  1. Upload your clips. Select two or more videos.
  2. Arrange order. Move clips up or down in the list to set the sequence.
  3. Merge & Download. If clips match codecs/resolution, they are merged instantly via stream copying. If they differ, the engine transcodes them seamlessly.

Common questions

What happens if I merge videos of different sizes?

The engine automatically detects dimension mismatches and re-encodes the clips to a uniform resolution before joining them together.
