This is guidance for writing Remotion React Markup. If this is not relevant, load Remotion Best Practices instead.

Preserve user changes

Users may make edits in the code outside of the conversation.

If you detect a surprising change made in the meanwhile, don't overwrite it, assume it was intentional or ask for confirmation.

General rules

Drive animations using useCurrentFrame() and interpolate().
CSS transition or animation will not render correctly, they need to refactored.
Tailwind animation class will not render correctly, they need to be refactored.

Use Easing.bezier() and Easing.spring() to customize timing.

Structure your markup according to Remotion Interactivity Best Practices

import { useCurrentFrame, Easing, interpolate, Interactive } from "remotion";

export const FadeIn = () => {
  const frame = useCurrentFrame();

  return (
    <Interactive.Div
      name="Title"
      style={{
        opacity: interpolate(frame, [0, 2 * fps], [0, 1], {
          extrapolateRight: "clamp",
          extrapolateLeft: "clamp",
          easing: Easing.bezier(0.16, 1, 0.3, 1),
        }),
      }}
    >
      Hello World!
    </Interactive.Div>
  );
};

Keep the interpolate() call inline in the style prop. Use scale, translate, rotate CSS properties over transform.

// 👍 Inline editable keyframes and transform shorthands
style={{
  scale: interpolate(frame, [0, 100], [0, 1], {
    extrapolateLeft: 'clamp',
    extrapolateRight: 'clamp',
    easing: Easing.spring({damping: 200}),
    output: 'perceptual-scale' // For `scale` animations, use "output: 'perceptual-scale'"
  }),
  translate: interpolate(frame, [0, 100], ["0px 0px", "100px 100px"], {
    extrapolateLeft: 'clamp',
    extrapolateRight: 'clamp',
    easing: Easing.spring({damping: 200}),
  }),
  rotate: interpolate(frame, [0, 100], ["20deg", "90deg"], {
    extrapolateLeft: 'clamp',
    extrapolateRight: 'clamp',
    easing: Easing.spring({damping: 200}),
  }),
}}

// 👎 Non-inline values and transform strings become harder to edit in Studio
const scale = interpolate(frame, [0, 100], [0, 1]);

style={{
  transform: `scale(${scale})`,
}}
