FAQ

Can I cut from the middle of a clip?

The editor supports start and end trim points. Cutting from the middle of a clip is not currently supported.

Will editing overwrite my original recording?

No. Trim edits are applied only when you export. Your source recording stays intact.

Can I re-edit a clip after exporting?
