snapcn

Find snapcn Remotion components for a scene by describing the beat in plain English. Returns ranked candidates with natural length, vibe and use/avoid notes. Use this instead of writing animation code.

Everything needed to use one snapcn component: install command, full prop table with defaults and ranges, a working example, when not to use it, and its frame budget.

Turn a one-line video brief into a beat-by-beat plan: archetype, duration, one registry component per beat with frame budgets, a single install command, and a ready TransitionSeries skeleton.

Render a frame of the video you just wrote and LOOK at it. Shells the user's own Remotion CLI (`remotion still`) and returns the frame as an image. Call it after writing a composition and after every fix: a snapcn scene missing mode="dark" on a dark frame renders BLACK, and that is invisible from the code. Requires the user's Remotion project — snapcn does not bootstrap it.

MEASURE a screen recording so content.recording is filled from data, not guessed. Returns crop, beatFrames and focus already in snapcn_plan_video's shape, plus one frame per beat cropped and fitted exactly as the composition will show it. Call it BEFORE snapcn_plan_video whenever the user has a recording: these are the three fields the contract says not to guess, and omitting them is not neutral — the default beat walk (0/139/278) only reaches 9.3s into a take of any length, so a 37s demo ships with its payoff never on screen.

The snapcn motion, design and anti-slop rules. Read before writing any scene chrome of your own — backdrops, cards, lower-thirds, easing.
