# \&greenscreen

Sender-Side Option! ([`&push`](https://docs.vdo.ninja/advanced-settings/setup-parameters/push))

## Details

`&greenscreen` is a shortcut for [`&effects=4`](https://docs.vdo.ninja/advanced-settings/video-parameters/effects). It enables a virtual greenscreen on the publisher side, removing the background and replacing it with solid green (#00FF00). This is useful when you want to do chroma-key compositing in OBS or another tool.

Please enable WebAssembly-SIMD support under `chrome://flags/` for significantly reduced CPU load when using this feature.
