Then, use `copyTo` to copy the pixel data into the destination buffer:
```ts
const bytes = new Uint8Array(bytesNeeded);
videoSample.copyTo(bytes);
const planeLayout = await videoSample.copyTo(bytes);
```
::: info
The data will always be in the pixel format specified in the `format` field.
To convert the data into a different pixel format, or to extract only a section of the frame, please use the [`allocationSize`](https://developer.mozilla.org/en-US/docs/Web/API/VideoFrame/allocationSize) and [`copyTo`](https://developer.mozilla.org/en-US/docs/Web/API/VideoFrame/copyTo) methods on `VideoFrame` instead. Get a `VideoFrame` by running `videoSample.toVideoFrame()`.
You can pass additional options to `allocationSize` and `copyTo` to extract data in a different pixel format.
