Write motion as code. Resolve any frame as a pure function.

Compile, resolve, render

Sequential to write

A scene reads like a storyboard: spawn, tween, wait, tween. yield* moves an authored cursor, and nothing plays while it runs.

Random access to read

at(frame) rebuilds one frame from the record. Frame 400 costs the same whether or not anything asked for frame 399.

Any backend draws it

Renderers for the DOM, Pixi, Three.js and Skia all read the same resolved frame.

Plays where you need it

One composition plays in Remotion, in HyperFrames, in the native preview and through the video exporter.

Host values have a door

Measured boxes, sensors and fetched data enter through channels. A cached frame is dropped only when a channel it read changes.

Testable without pixels

Compile a scene, resolve a frame and assert on the actors, with no canvas or browser involved.
