+Drive motion with `interpolate()` over an explicit frame range. 
+To customize timing, use **`Easing.bezier`** or `Easing.spring`.
+
+A simple linear interpolation is done using the `interpolate` function.
+
+```ts title="Going from 0 to 1 over 0.3 seconds"
+import { interpolate } from "remotion";
+
+const opacity = interpolate(frame, [0, 0.3 * fps], [0, 1]);
+```
+
+By default, the values are not clamped, so the value can go outside the range [0, 1].  
+Here is how they can be clamped:
+
+```ts title="Going from 0 to 1 over 0.3 seconds with extrapolation"
+const opacity = interpolate(frame, [0, 0.3 * fps], [0, 1], {
+  extrapolateRight: "clamp",
+  extrapolateLeft: "clamp",
+});
+```
+
+## Studio-editable animation patterns
+
+When an animation should be editable in Remotion Studio, keep the `interpolate()` call directly in the `style` prop and prefer individual CSS transform properties:
+
+```tsx
+// 👍 Inline editable keyframes and transform shorthands
+style={{
+  scale: interpolate(frame, [0, 100], [0, 1]),
+  translate: interpolate(frame, [0, 100], ["0px 0px", "100px 100px"]),
+  rotate: interpolate(frame, [0, 100], ["20deg", "90deg"]),
+}}
+
+// 👎 Hidden values and transform strings become computed in Studio
+const translateY = interpolate(frame, [0, 100], [0, 120]);
+const rotation = interpolate(frame, [0, 100], [0, 20]);
+
+style={{
+  transform: `translateY(${translateY}px) rotate(${rotation}deg)`,
+}}
+```
+
+Use `transform` strings only when individual CSS transform properties do not cover the effect, such as `skew()`, `perspective()`, or order-sensitive multi-transform chains.
+
+## Spring easing
+
+A nice push movement with no bounce:
+
+```ts
+import { interpolate, Easing } from "remotion";
+
+const opacity = interpolate(frame, [0, 0.3 * fps], [0, 1], {
+  easing: Easing.spring({damping: 200}),
+  extrapolateLeft: "clamp",
+  extrapolateRight: "clamp",
+});
+```
+
+## Bézier easing
+
+Pass values like you would to a CSS cubic-bezier function.
+
+```ts
+import { interpolate, Easing } from "remotion";
+
+const opacity = interpolate(frame, [0, 0.3 * fps], [0, 1], {
+  easing: Easing.bezier(0.16, 1, 0.3, 1),
+  extrapolateLeft: "clamp",
+  extrapolateRight: "clamp",
+});
+```
+
+## Animating scale
+
+When animating scale, if the output is linear, the perceived scale would be smaller the larger the scale gets.  
+Use this option to compensate:
+
+```ts
+const scale = interpolate(frame, [0, 0.3 * fps], [0, 1], {
+  easing: Easing.bezier(0.16, 1, 0.3, 1),
+  extrapolateLeft: "clamp",
+  extrapolateRight: "clamp",
+  output: 'perceptual-scale' // <- Add this to scale animations
+});
+```
+
+## Multiple keyframes
+
+Add as many keyframes as you want. For multiple easings, pass an array with `n - 1` items:
+
+```ts
+const scale = interpolate(frame, [0, 1 * fps, 9 * fps, 10 * fps], [0, 1, 1, 0], {
+  easing: [Easing.bezier(0.16, 1, 0.3, 1), Easing.linear, Easing.spring({damping: 200})],
+  extrapolateLeft: "clamp",
+  extrapolateRight: "clamp",
+  output: 'perceptual-scale' // <- Add this to scale animations
+});
+```
+
+## Posterization
+
+You can intentionally reduce the frame rate for artistic reason. Use if it makes sense.
+
+```ts
+const scale = interpolate(frame, [0, 1 * fps], [0, 1], {
+  easing: Easing.bezier(0.16, 1, 0.3, 1),
+  extrapolateLeft: "clamp",
+  extrapolateRight: "clamp",
+  posterize: 3 // Only every 3rd frame is sampled
+});
+```
