# Screen capture

> A window, tab or whole display as one video stream, chosen by the person each time it starts.

Source: https://docs.tune.toys/nodes/video.display/

Screen capture shares a window, a browser tab or the whole display as one video stream.

## What it does

Each time the Toy starts, the browser asks the person what to share. The output is one stream of frames, newest frame wins. It has no parameters. The Toy stores nothing about what was shared and never records or uploads it.

## When to use it

Use it to bring a presentation, game or another app into a Toy for filtering, compositing or recording.

## Ports

<!-- ports:start -->

| Port    | Direction | Signal | Lanes |
| ------- | --------- | ------ | ----- |
| `video` | Output    | Video  | 1     |

<!-- ports:end -->

## Parameters

<!-- parameters:start -->

This node has no numeric parameters.

<!-- parameters:end -->

<!-- data:start -->

- `label`: text.

<!-- data:end -->

This node has no parameters.

## Tips

- The choice is made by the person every time; it cannot be pre-selected by the Toy.
- Video needs the browser's WebGPU video engine. The Player and exports do not run video yet and report it unavailable. To see a video output, bind a live Screen in the Frame to it.
