+---
+
+All animations MUST be driven by the `useCurrentFrame()` hook.  
+Write animations in seconds and multiply them by the `fps` value from `useVideoConfig()`.
+
+For eased motion, prefer `interpolate` with explicit frame ranges and an easing—especially `Easing.bezier`, which matches CSS `cubic-bezier` so timing can be shared with web specs and curve editors. See [timing](./timing.md).
+
+```tsx
+import { useCurrentFrame, Easing } from "remotion";
+
+export const FadeIn = () => {
+  const frame = useCurrentFrame();
+  const { fps } = useVideoConfig();
+
+  const opacity = interpolate(frame, [0, 2 * fps], [0, 1], {
+    extrapolateRight: "clamp",
+    extrapolateLeft: "clamp",
+    easing: Easing.bezier(0.16, 1, 0.3, 1),
+  });
+
+  return <div style={{ opacity }}>Hello World!</div>;
+};
+```
+
+CSS transitions or animations are FORBIDDEN - they will not render correctly.  
+Tailwind animation class names are FORBIDDEN - they will not render correctly.
