Features · Aspect ratios

16:9 · 9:16 · 1:1 from one capture.

Re-cropped via the camera transform. No recapture. Same script, three deliverables: docs embed, social ad, square.

How

Crop happens in render, not capture

Capture always happens in the demo's CSS viewport size. The camera transform in Remotion maps that source space into the chosen output frame. Switching aspect ratios is a render-time flag — no re-execution of the script.

Every render of this feature is deterministic. Capture writes the metadata; the composition reads it. Re-render after a UI change to get the new output without re-recording.
