beats — the shared map

open-take beats demos/myapp.mp4

Prints the numbered beat sheet — the map that notes like beat 3: no zoom refer to. --card appends the say-it cheat card.

frames — framing checks without a render

open-take frames demos/myapp.mp4
open-take frames demos/myapp.mp4 --beat 3

Extracts a beat-aware contact sheet (frames.png) from the delivered mp4: an intro row, one row per beat — a mid-travel cell plus four samples across the beat's camera hold, timed off the real camera schedule — and a tail row. Pure ffmpeg, seconds, no render.

--beat N densifies one beat into a 10-cell strip with per-cell phase labels. --tile <px> sets tile width (default 480; a --beat strip defaults 720 — thumbnails suspect a framing bug, bigger tiles confirm it). Judge framing on hold cells, never mid-ramp. Pass draft.mp4 or review.mp4 as <take> to sample that copy instead of the master.

ab — taste questions, answered by eye

open-take ab demos/myapp.mp4 --set zoom=light,tight --beat 3
open-take ab demos/myapp.mp4 --set look=slate,midnight
open-take ab demos/myapp.mp4 --before-after

One knob, up to three candidate values, rendered as a labeled reel — each variant plays twice, and variant A is always the current state. Knobs: zoom (per-beat, off/light/medium/tight/close or a number) · look (midnight/ink/slate/ocean/plum/ember/paper/plain) · pace (calm/natural/brisk) · finish (smooth/crisp/heavy) · or a raw dot-path like cursor.holdMs=900,1300.

Reels are windowed to the beat's zoom arc (--full for the whole take); feel knobs render at full quality — judge motion by eye. --before-after replays prev.mp4 vs the current master instead: no render, BEFORE then AFTER, twice.
