Improve Remotion Studio rendering performance by limiting which components update with every frame. The skill guides on-demand timeline reads and React.memo usage, helping keep stable components from rerendering unnecessarily while preserving updates where the displayed frame matters.

Optimize Remotion Studio render performance by minimizing frame-reactive component surfaces, preferring imperative timeline state reads, and memoizing stable render boundaries. Use when code reads the current frame with `useTimelinePosition()` or components unnecessarily render on every frame.

适用场景

  • Reduce unnecessary rerenders on every frame
  • Read the current frame only when an event needs it
  • Move frame-dependent rendering into a small child component
  • Review React.memo usage and prop stability

Studio Performance

Minimize frame subscriptions

Keep dependencies on the current frame as low in the component tree as possible. Prefer imperative timeline state reads such as getCurrentFrame() over Internals.Timeline.useTimelinePosition() for event handlers and other on-demand logic.

Use useTimelinePosition() only in the smallest leaf component whose rendered output must change with the frame. If a parent reads the frame only to pass it to a child, extract a frame-subscribing child so the parent and its other descendants stay stable.

Memoize stable boundaries

Wrap components in React.memo() when they can safely skip parent-driven renders. Confirm that their props remain referentially stable across frame updates: newly created objects, callbacks, styles, or React nodes defeat shallow memoization. Stabilize those props only where it is natural; avoid custom comparators that ignore behaviorally relevant changes.

Context subscribers continue to update through memoized ancestors. Prefer a memoized stable parent with a small frame-subscribing leaf over making the whole subtree reactive to the current frame.
