# Video Bitrate Parameters

They are separated in two groups: [source side](#source-side-options) (push) options for the sender of the video and [viewer side](#viewer-side-options) (view) options for the viewer of the video. Some of them are especially for rooms.

Viewer-side `&videobitrate` overrides the sender default from `&outboundvideobitrate`, while `&maxvideobitrate` remains a software-enforced cap. Room-level limits still apply where relevant.

Depending on browser/negotiation, `&videobitrate` and `&outboundvideobitrate` can also be enforced via SDP munging and may act as caps.

## Source side options

You have to add them to the source side ([`&push`](https://docs.vdo.ninja/advanced-settings/setup-parameters/push)).

## **Viewer side options**

You have to add them to the viewer side ([`&room`](https://docs.vdo.ninja/advanced-settings/setup-parameters/room) or [`&view`](https://docs.vdo.ninja/advanced-settings/mixer-scene-parameters/view) or [`&scene`](https://docs.vdo.ninja/advanced-settings/mixer-scene-parameters/scene) or [`&solo`](https://docs.vdo.ninja/advanced-settings/mixer-scene-parameters/and-solo)).
