About studio-perf
A skill with React Studio performance guidance for Remotion, focused on limiting frame subscriptions and keeping stable component boundaries memoized. It helps developers avoid unnecessary renders as the timeline frame changes.
Key features
- 01Keep frame subscriptions low in the tree
- 02Use imperative frame reads for on-demand logic
- 03Isolate frame-reactive leaf components
- 04Memoize stable components with React.memo()
- 05Keep memoized props referentially stable
Use cases
- 01Reducing rerenders during timeline playback
- 02Refactoring a parent that passes frame state to children
- 03Choosing between frame subscriptions and imperative reads

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.
