+description: Make a video parametrizable by adding a Zod schema
+metadata:
+  tags: parameters, zod, schema
+---
+
+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(),
+});
+```
