This is guidance for writing Remotion React Markup. If this is not relevant, load [Remotion Best Practices](../remotion-best-practices/SKILL.md) 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](../remotion-interactivity/SKILL.md)

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})`,
}}

Assets

Place assets in the `public/` folder at your project root. Use `staticFile()` to reference files from the `public/` folder.

Media components

Add video and audio using `<Video>` and `<Audio>` from `@remotion/media`. Add images using the `<CanvasImage>` component. Add animated GIFs, APNG, WebP or AVIF images using `<AnimatedImage>`, use `@remotion/gif` if not using Chrome. Use `staticFile()` for files in `public/` or pass a remote URL directly:

import { Audio, Video } from "@remotion/media";
import { staticFile, CanvasImage, AnimatedImage } from "remotion";

export const MyComposition = () => {
  return (
    <>
      <Video src={staticFile("video.mp4")} style={{ opacity: 0.5 }} />
      <Audio src={staticFile("audio.mp3")} />
      <CanvasImage
        src={staticFile("logo.png")}
        style={{ width: 100, height: 100 }}
      />
      <Video src="https://remotion.media/video.mp4" />
      <AnimatedImage src={staticFile('nyancat.gif')} />
    </>
  );
};

Example scene

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

export const Empty = () => {
  const {fps} = useVideoConfig();
  const frame = useCurrentFrame();

  return (
    <AbsoluteFill
      name="Scene"
      style={{
        display: 'flex',
        justifyContent: 'center',
        alignItems: 'center',
        backgroundColor: 'white'
      }}
    >
      <Interactive.Div
        name="Title"
        style={{
          opacity: interpolate(frame, [1 * fps, 2 * fps], [0, 1], {
            extrapolateRight: "clamp",
            extrapolateLeft: "clamp",
            easing: Easing.bezier(0.16, 1, 0.3, 1),
          }),
          fontSize: 88
        }}
      >
        Title
      </Interactive.Div>
      <Interactive.Div
        name="Subtitle"
        style={{
          opacity: interpolate(frame, [2 * fps, 3 * fps, 8 * fps, 10 * fps], [0, 1, 1, 0], {
            extrapolateRight: "clamp",
            extrapolateLeft: "clamp",
            easing: [Easing.bezier(0.16, 1, 0.3, 1), Easing.linear, Easing.bezier(0.16, 1, 0.3, 1)],
          }),
          fontSize: 32
        }}
      >
        Subtitle
      </Interactive.Div>
    </AbsoluteFill>
  );
}

Delaying, trimming

Most components (`<AbsoluteFill>`, `<Interactive.*>` `<Img>`, `<AnimatedImage>`, `<CanvasImage>`, `<HtmlInCanvas>`, `<Solid>`, `<Sequence>` from `remotion`, `<Video>` and `<Audio>` from `@remotion/media`, `<Gif>`, and more) support the following props:

from

<Img from={1 * fps} {/* ... */}/>
<Video from={1 * fps} {/* ... */}/>
<Interactive.Div from={1 * fps} {/* ... */}/>

When the element starts appearing in the timelien.

durationInFrames

<Img durationInFrames={20 * fps} {/* ... */}/>
<Interactive.Div durationInFrames={20 * fps} {/* ... */}/>

For how long the layer plays in the timeline. For media, pass the natural duration of the media: `<Video durationInFrames={29.322 * fps}/>`

`trimBefore`

Useful for components whose internal clock should start later:

// Trim away first 2 seconds of footage
<Video trimBefore={2 * fps} {/* ... */} />

// `useCurrenFrame()` for children starts at `10 * fps`
<Sequence trimBefore={10 * fps} {/* ... */} />

Fallback

If a component does not support these props, wrap it in`<Sequence>` from `remotion`, which has them.

• `layout="absolute-fill"` makes the Sequence behave like AbsoluteFill
• `layout="none"` is "headless" mode, no wrapper element is used.
