What this does
Tracks every timeline change and AI edit so you can experiment freely without losing prior work.
Everything Cubix does in a single response is grouped as one edit. If it punched in on eight clips, one undo removes all eight — not just the last zoom. This is deliberate: it means you can take back a whole edit in one press instead of unpicking it operation by operation.
How to do it
Follow these step-by-step instructions in Cubix.
Use the undo and redo buttons
The pair sits in the editor header, next to your project name, and is always available. The timeline has its own pair too, but the header buttons stay put even when the timeline is collapsed — so canvas changes like framing, cropping and quick edits always have a way back.
Or use the keyboard
Cmd + Z (Mac) or Ctrl + Z (Windows) steps backward. Cmd + Shift + Z or Ctrl + Shift + Z steps forward.
Read what came back
Cubix names each step as you take it — 'Undid: Add Captions' rather than a bare confirmation — so you can see exactly which change was removed before deciding whether to keep going.
Or ask the agent
You can also tell Cubix directly: 'undo that' or 'put it back'. It reports which edit it removed.
Pro Tips for Best Results
- When an edit is mostly right, describe the correction instead of undoing. You keep the good work and change only what you named.
- Passes applied from the quick edit rail each carry their own Revert, so you can remove one treatment while leaving the rest of the edit intact.
- Your work saves continuously in the background, so there is nothing to lose by trying something.
- Redo is available right up until you make a new change — once you edit again from an undone state, the forward history is replaced by the new one.
Because editing is non-destructive, undo is never your only safety net. Your uploaded media is untouched no matter how far the edit has gone, so even an unrecoverable timeline can be rebuilt from the original files.
