To make a video parametrizable, a Zod schema can be added to a composition.
First, `zod` must be installed .
Search the project for lockfiles and run the correct command depending on the package manager:
If `package-lock.json` is found, use the following command:
```bash
npm i zod
```
If `bun.lockb` is found, use the following command:
```bash
bun i zod
```
If `yarn.lock` is found, use the following command:
```bash
yarn add zod
```
If `pnpm-lock.yaml` is found, use the following command:
```bash
pnpm i zod
```
Then, a Zod schema can be defined alongside the component:
```tsx title="src/MyComposition.tsx"
import { z } from "zod";
export const MyCompositionSchema = z.object({
title: z.string(),
});
const MyComponent: React.FC<z.infer<typeof MyCompositionSchema>> = () => {
return (
<div>
<h1>{props.title}</h1>
</div>
);
};
```
In the root file, the schema can be passed to the composition:
```tsx title="src/Root.tsx"
import { Composition } from "remotion";
import { MycComponent, MyCompositionSchema } from "./MyComposition";
export const RemotionRoot = () => {
return (
<Composition
id="MyComposition"
component={MyComponent}
durationInFrames={100}
fps={30}
width={1080}
height={1080}
defaultProps={{ title: "Hello World" }}
schema={MyCompositionSchema}
/>
);
};
```
Now, the user can edit the parameter visually in the sidebar.
All schemas that are supported by Zod are supported by Remotion.
Remotion requires that the top-level type is a z.object(), because the collection of props of a React component is always an object.
## Color picker
For adding a color picker, use `zColor()` from `@remotion/zod-types`.
If it is not installed, use the following command:
```bash
npx remotion add @remotion/zod-types # If project uses npm
bunx remotion add @remotion/zod-types # If project uses bun
yarn remotion add @remotion/zod-types # If project uses yarn
pnpm exec remotion add @remotion/zod-types # If project uses pnpm
```
Then import `zColor` from `@remotion/zod-types`:
```tsx
import { zColor } from "@remotion/zod-types";
```
Then use it in the schema:
```tsx
export const MyCompositionSchema = z.object({
color: zColor(),
});
```
