How do you merge files in an open source video editor?

To merge video files in an open-source editor like FilmCraft, you line the clips up on the timeline one after another and export the whole sequence as one file. FilmCraft is a nonlinear editor, so you bring your clips in, drop them on a track in the order you want, and if you leave a gap, its ripple delete and close gap tools pull everything together. Then you export the entire sequence, and according to its GitHub page the export writes H.264 MP4 with AAC audio using its own encoders.

So the merge is really just the export: one sequence in, one file out. If your clips come from different phones, I'd watch every join, because the team says camera and phone files in the wild are less tested and the app is still alpha. And the part I like is that every action in FilmCraft is a command, and it has an MCP server, so Claude can place clips and export for you the same way you would. I'd still watch the result before it goes anywhere. My guide to setting up the ArtCraft apps with Claude Code covers the safe download and the MCP connection, starting with PhotoCraft.
