FeaturesEdit, finish & record

PRODUCE

Save a version before the risky edit. Restore it in one click.

History keeps named snapshots of the entire timeline — clips, transitions, markers, captions. Every export and every storyboard re-prep also leaves an automatic copy. Restoring runs through the same conflict check as autosave, so two open tabs can never clobber each other.

What it does

The detail that makes it work.

Readable diffs

Added, removed, moved, retimed and reordered clips, plus the duration delta — before you restore.

Automatic safety copies

“Before export” and “before re-prep” versions are kept for you, pruned to the last 25.

Restore is itself a version

A restore saves a “before restore” copy first, so there is always a way back.

It’s one part of a tool that carries your source all the way to a polished, finished video.
