From b184e6e38398733aacde041cb4d81924cf27672e Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 1 Feb 2026 06:24:41 +0000 Subject: [PATCH 01/11] Add manual frame rendering API for environments without requestAnimationFrame This adds support for manually advancing animations in environments where requestAnimationFrame is unavailable, such as WebXR immersive sessions, Remotion video rendering, or server-side rendering of animations. New APIs: - renderFrame({ timestamp, frame, fps, delta }) - Manually render a frame - setManualTiming(enabled) - Enable/disable manual timing mode globally - isManualTiming() - Check if manual timing is enabled - useManualFrame({ frame, fps }) - React hook for Remotion integration Fixes #2496 https://claude.ai/code/session_01AFhy8F8ubRRHsau2GRdYAZ --- packages/framer-motion/src/index.ts | 1 + .../src/utils/use-manual-frame.ts | 96 +++++++++ .../frameloop/__tests__/render-frame.test.ts | 188 ++++++++++++++++++ packages/motion-dom/src/frameloop/batcher.ts | 27 ++- packages/motion-dom/src/frameloop/frame.ts | 1 + packages/motion-dom/src/frameloop/index.ts | 1 + .../motion-dom/src/frameloop/render-frame.ts | 122 ++++++++++++ 7 files changed, 435 insertions(+), 1 deletion(-) create mode 100644 packages/framer-motion/src/utils/use-manual-frame.ts create mode 100644 packages/motion-dom/src/frameloop/__tests__/render-frame.test.ts create mode 100644 packages/motion-dom/src/frameloop/render-frame.ts diff --git a/packages/framer-motion/src/index.ts b/packages/framer-motion/src/index.ts index dfb2e0a91a..e863eda118 100644 --- a/packages/framer-motion/src/index.ts +++ b/packages/framer-motion/src/index.ts @@ -95,6 +95,7 @@ export { useInstantLayoutTransition } from "./projection/use-instant-layout-tran export { useResetProjection } from "./projection/use-reset-projection" export { buildTransform, visualElementStore, VisualElement } from "motion-dom" export { useAnimationFrame } from "./utils/use-animation-frame" +export { useManualFrame } from "./utils/use-manual-frame" export { Cycle, CycleState, useCycle } from "./utils/use-cycle" export { useInView, UseInViewOptions } from "./utils/use-in-view" export { diff --git a/packages/framer-motion/src/utils/use-manual-frame.ts b/packages/framer-motion/src/utils/use-manual-frame.ts new file mode 100644 index 0000000000..841831867d --- /dev/null +++ b/packages/framer-motion/src/utils/use-manual-frame.ts @@ -0,0 +1,96 @@ +"use client" + +import { renderFrame, setManualTiming } from "motion-dom" +import { useContext, useEffect, useRef } from "react" +import { MotionConfigContext } from "../context/MotionConfigContext" + +interface UseManualFrameOptions { + /** + * The current frame number (0-indexed). + * Typically from Remotion's `useCurrentFrame()`. + */ + frame: number + + /** + * Frames per second of the video/animation. + * Typically from Remotion's `useVideoConfig().fps`. + * @default 30 + */ + fps?: number +} + +/** + * A hook for manually controlling Motion animations based on a frame number. + * + * This is designed for integration with video rendering frameworks like Remotion, + * or any environment where `requestAnimationFrame` is unavailable or + * animations need to be driven by an external timing source. + * + * @example + * // Basic usage with Remotion + * import { useCurrentFrame, useVideoConfig } from 'remotion' + * import { useManualFrame } from 'motion/react' + * + * function MyComponent() { + * const frame = useCurrentFrame() + * const { fps } = useVideoConfig() + * + * // This syncs Motion animations to Remotion's frame + * useManualFrame({ frame, fps }) + * + * return ( + * + * ) + * } + * + * @example + * // With a custom frame source + * function MyComponent({ frame }: { frame: number }) { + * useManualFrame({ frame, fps: 60 }) + * + * return ( + * + * ) + * } + */ +export function useManualFrame({ frame, fps = 30 }: UseManualFrameOptions) { + const { isStatic } = useContext(MotionConfigContext) + const prevFrame = useRef(-1) + const hasInitialized = useRef(false) + + // Enable manual timing on mount, disable on unmount + useEffect(() => { + if (isStatic) return + + setManualTiming(true) + + return () => { + setManualTiming(false) + } + }, [isStatic]) + + // Render the frame when it changes + useEffect(() => { + if (isStatic) return + + // Only render if frame has changed or on first render + if (frame !== prevFrame.current || !hasInitialized.current) { + const delta = + hasInitialized.current && prevFrame.current >= 0 + ?

How it works:

+
    +
  • + Manual Timing Mode: Disables + requestAnimationFrame-based updates +
    • +
  • + Next/Prev Frame: Advance or rewind by + one frame (~33ms at 30fps) +
    • +
  • + Frame Slider: Scrub through the + animation timeline +
    • +
  • + FPS: {fps} frames per second ( + {(1000 / fps).toFixed(1)}ms per frame) +
    • +

Create motion-remotion package with remotionDriver and useRemotionFrame hook - Add MotionGlobalConfig.driver for custom animation drivers - Disable WAAPI when custom driver or useManualTiming is active - Update batcher to skip rAF scheduling with custom driver - Export Driver type and frameloopDriver from motion-dom - Remove useManualFrame from framer-motion (moved to motion-remotion) - Add waapi supports tests for driver/timing checks Co-Authored-By: Claude Opus 4.5 --- packages/framer-motion/src/index.ts | 1 -
