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})`,
}}

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.
