# Video bitrate in rooms This guide will show you how to control and set up the bitrate in rooms as a director and as a guest. ## Default settings Every guest is viewing video streams in a room with a combined bitrate of 500-kbps. If there is only one video stream, the guest will view the video on 500-kbps. Two video streams: 250-kbps per video. For guest-only room calls, VDO.Ninja may use higher automatic room-only bitrate tiers. These tiers are designed for conferencing-style rooms where there is no director or scene viewer connected to the guest. See [Room-only mobile bitrate tiers](/guides/room-only-mobile-bitrate-tiers.md) for details. ## Director As a director of a room you can control the total room bitrate dynamically.

Open the room settings via this button as a director

The default is (as explained before) 500-kbps. You can increase it up to 4000-kbps by default (the slider max increases if a higher &totalroombitrate is set).

You can control the total room bitrate also with a URL parameter: [`&totalroombitrate=6000`](/advanced-settings/video-bitrate-parameters/and-totalscenebitrate/totalroombitrate.md) (alias: `&totalbitrate=6000`)

Default is 6000-kbps now with &totalroombitrate=6000

When the director joins with `&totalroombitrate=6000`, that value becomes the default for all guests by proxy. You can decrease it dynamically though if the guests have any problems. ## Guest If you add [`&roombitrate=2000`](/advanced-settings/video-bitrate-parameters/roombitrate.md) to the guest's link all the other guests can view the video of the guest with a bitrate of 2000-kbps. So three other guests watching the video stream of the guest -> 6000-kbps outgoing bitrate. [`&roombitrate`](/advanced-settings/video-bitrate-parameters/roombitrate.md) limits any guest viewer in the group chat room from pulling the video stream at more than the specified bitrate value. You can also use [`&totalroombitrate`](/advanced-settings/video-bitrate-parameters/and-totalscenebitrate/totalroombitrate.md) on the guest's URL if you want to have different settings for each guest. So adding `&totalroombitrate=4000` to a guest's URL, the guest can view all video streams in the room with a combined bitrate of 4000-kbps. If `&totalroombitrate` is not set on a room link, `&videobitrate` will be used as the total room bitrate target for that guest. If you use [`&controlroombitrate`](/advanced-settings/video-bitrate-parameters/and-controlroombitrate.md) on the guest's URL, the guest can change the total room bitrate dynamically via a slider. If you add `&controlroombitrate&totalroombitrate=4000` to the guest's URL the guest can change the bitrate between 0 and 4000-kbps (it cannot exceed the `&totalroombitrate` cap). It doesn't affect what other guest's are viewing. ![](/files/RuNvQbiHSfaAodNTWPAv) ![](/files/cMeren4U5rKpUb4iHEll) ## Examples \ When adding `&broadcast&totalroombitrate=5000` to the director's URL the guests can only see the video of the director with a bitrate of 5000-kbps. So they get pretty good video quality. If you have three guests in the room the outgoing bitrate fot the director is 15000-kbps, so it's pretty high. If you want a guest to appear in scenes (for example in OBS) but you don't want other guests to see their video stream you can add `&roombitrate=0` to the guest's URL. [`&roombitrate`](/advanced-settings/video-bitrate-parameters/roombitrate.md) only affects the bitrate in the room, not in scenes. Adding [`&maxbandwidth=80`](/advanced-settings/video-bitrate-parameters/and-maxbandwidth.md) to the guest's URL will allow to them to put 80 % of their available bandwidth into the video stream. This is useful for high quality gaming streams for example. ## Scenes For scenes in OBS or other softwares ([`&scene`](/advanced-settings/mixer-scene-parameters/scene.md) or [`&solo`](/advanced-settings/mixer-scene-parameters/and-solo.md)) use [`&videobitrate`](/advanced-settings/video-bitrate-parameters/bitrate.md) to specify the bitrate per video stream or [`&totalscenebitrate`](/advanced-settings/video-bitrate-parameters/and-totalscenebitrate.md) to get a combined bitrate for all videos in the scene. 3 guests in a scene -> `&videobitrate=3000`\ The bitrate of each guest will be 3000-kbps. 3 guests in a scene -> `&totalscenebitrate=3000`\ The bitrate of each guest will be 1000-kbps. ## Notes and caveats * Screen shares are weighted differently in the room mixer; they can take a larger share of the total budget versus camera feeds. * Hidden, muted, or disabled videos are not counted when the room bitrate is split across streams. * `&minroombitrate` can enforce a per-stream floor when splitting a total room bitrate. * Automatic room-only mobile tiers do not apply when a guest is connected to a director or scene viewer. In those production-style rooms, set `&totalroombitrate`, `&roombitrate`, `&videobitrate`, or `&totalscenebitrate` explicitly depending on whether you are tuning guest-to-guest room quality or scene quality. ## Meshcast If you are using [`&meshcast`](/advanced-settings/meshcast-parameters/and-meshcast.md) on the director's or guest's URL remember that you control the bitrate via [`&meshcastbitrate`](/advanced-settings/meshcast-parameters/and-meshcastbitrate.md) on the sender's side. ## More Parameters There are more parameters to control the bitrate.
