Remotion Best Practices

## When to use

Use this skills whenever you are dealing with Remotion code to obtain the domain-specific knowledge.

## New project setup

When in an empty folder or workspace with no existing Remotion project, scaffold one using:

```bash
npx create-video@latest --yes --blank --no-tailwind my-video
```

Replace `my-video` with a suitable project name.

## Designing a video

Animate properties using `useCurrentFrame()` and `interpolate()`. Use Easing to customize the timing of the animation.

```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.

Place assets in the `public/` folder at your project root.

Use `staticFile()` to reference files from the `public/` folder.

Add images using the `<Img>` component:

```tsx
import { Img, staticFile } from "remotion";

export const MyComposition = () => {
  return <Img src={staticFile("logo.png")} style={{ width: 100, height: 100 }} />;
};
