SVG Character Animation
Use this skill when animating character rigs made from SVG parts.
Runtime Rules
- Animate transforms (
x, y, scale, rotation) rather than layout.
- Use timelines for multi-part acting beats.
- For SVG elements, use stable pivots (
svgOrigin or correctly scoped
transform origins).
- In Remotion, do not let GSAP advance with
requestAnimationFrame; drive a
paused timeline from the current frame.
Browser Pattern
gsap.set("#arm_right", { svgOrigin: "390 310" });
const tl = gsap.timeline({ defaults: { ease: "power2.inOut" } });
tl.to("#head", { rotation: -8, duration: 0.2 })
.to("#arm_right", { rotation: 35, duration: 0.4 }, "<");
Remotion Pattern
const frame = useCurrentFrame();
const progress = frame / durationInFrames;
timeline.progress(progress);
HyperFrames Pattern
Use HTML/SVG/GSAP components with deterministic timelines and validate via the
HyperFrames CLI before final render.
Quality Checklist
- Parts stay connected at pivots during motion.
- Blinks, gaze, and mouth shapes are separate enough to read.
- Pose holds are long enough to communicate emotion.
- Frame sampling shows meaningful deltas, not frozen animation.
