Common questions

Where does my video go after export?

Straight into your photo library, as a 1080×1920 vertical MP4 with the music baked in. Share it from Photos like any other video.

Can I use my own music?

Yes. Tap Add a song on the home screen and pick an MP3 or WAV from Files. ChaosCut finds the beat on your phone — nothing is uploaded — and the song then shows up under Your audio in every reel's beat picker. The bundled templates come with hand-tuned beat maps; for your own songs you can check and adjust the cuts before using them.

Some of my clips weren't used. Why?

When you add more clips than the track has beat windows, ChaosCut keeps the liveliest ones spread across the day. Star a clip to guarantee it's in, or open the editor and use Replace on any segment.

A clip from iCloud is slow to load.

Clips that only live in iCloud are downloaded while the project analyzes. Give it a moment on Wi-Fi; export never waits on the network.

I made a mess in the editor.

Undo is in the editor toolbar and every edit is reversible. You can also go back to the beat picker and re-cut; you'll be asked before your edits are replaced.

How do I delete my data?

Delete a project inside the app to remove its copies of your media. Deleting the app removes everything.
