The editor

open-take edit demos/myapp.mp4

Opens a local visual editor on the take: the live, pixel-faithful preview with an icon-rail of layered settings and a timeline with zoom blocks. Everything runs on 127.0.0.1; nothing is uploaded.

What it does

• Stage — the preview canvas. Selecting a zoom block enters an inspect view where the zoom region is a draggable, resizable box: drag moves zoom.center, corners set zoom.scale, aspect locked to the output.
• Panels — Zoom · Background looks · Frame · Cursor · Motion (pace, blur, fine-tune durations) · Clip · Agent. Labels match the composition.json field they write, so the GUI, the CLI and your agent share one vocabulary.
• Timeline — transport, ruler, filmstrip thumbnails, iris zoom blocks (dashed ghosts enable a zoom on a beat), synced playhead.
• Compare — hold to see the take as the editor loaded it.
• Export — renders the real mp4 with live progress. The master it replaces is kept as prev.mp4.

Edits autosave; there is no Save button. If your agent edits the composition while the editor is open, clean drafts adopt the change automatically and dirty drafts ask — Keep mine or Take theirs.

The Agent panel

Anything the editor can't do (reorder beats, re-record) it hands to your agent: notes typed in the panel land in <base>.take/notes.md and print on the edit server's terminal. On the agent side:

open-take notes --wait

blocks until a note lands — start it in the background when you open the editor, and its exit is the wake-up. Both doors write the same composition.json.
