One recording, many timelines

Record once, publish everywhere: a project holds several timelines, each an independent cut of the same media. The tabs above the timeline switch between them.

What’s independent per timeline

Everything editorial: trims, cuts and clip arrangement; the canvas (aspect ratio, background, padding); zooms; caption styling; masks. A 16:9 YouTube cut, a tight vertical for Shorts, and a square LinkedIn version live side by side without duplicating a byte of media.

Working with them

• ＋ next to the tabs adds a timeline (duplicate the current cut as a starting point, or start clean).
• Rename or delete from the tab’s context menu.
• Each timeline exports on its own — pick the tab, then export.

Timelines inside timelines

• Nest: drag a timeline’s tab onto the timeline. It lands as one amber block, labelled with its name, at the point you drop it. A block holds pictures, videos and text — a timeline with sound, captions, zooms or masks can’t be nested — and nesting goes one level deep.
• Insert: the stack button in the timeline bar copies another timeline’s clips in at the playhead as ordinary clips.
• Extract: select several clips, right-click, and choose Move Selection to New Timeline.

A workflow that works

1. Cut the full-length landscape version first — trims, zooms, captions.
2. Duplicate it, switch the canvas to 9:16, and tighten: bigger captions, crop to the action, bigger cursor.
3. Duplicate again for square, adjust, done.

Fixing a flubbed word is a per-timeline edit — each cut owns its trims — but media-level things (a re-recorded take, captions’ transcript) are shared, so the fix lands everywhere it should.
