render

open-take render demos/myapp.mp4            # re-render the master
open-take render demos/myapp.mp4 --review   # badged review copy
open-take render demos/myapp.mp4 --draft    # clean fast draft

render re-renders the (edited) composition.json over the kept capture. The app is not driven — the result is deterministic, and the previous master is kept as prev.mp4 so "keep the old one" is a mechanical revert.

--review

Renders a fast draft to review.mp4 with beat badges burned in — the video teaches what "beat 3" refers to — plus a REVIEW watermark. Never overwrites the postable master. Review copies auto-open in the player (--no-open to skip, --reveal to reveal the file instead).

--draft

Renders a clean draft to draft.mp4 — 30 fps cap, motion blur off, no badges — the cheap re-render for frame checks mid-refine. Never overwrites the master, does not auto-open.

Warnings land in the summary

The composition validator refuses to hand you a bad take quietly: a camera still mid-move at a click, a dead tail, a crowded release — each is flagged in the end-of-run summary with the fix.
