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. Open the Songs tab and tap +, then pick an MP3 or WAV from Files, or take the sound from a video. ChaosCut finds the cuts on your phone — nothing is uploaded — and you can let it place them, tap them along to the music, or set every one by hand. The song then shows up under Your audio in every reel's beat picker, and you can check its cuts again any time from Songs.

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 by iOS while the reel is being cut. 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 reel inside the app to remove its copies of your media, and remove a song from the Songs tab to delete it. Deleting the app removes everything.
