# Video bitrate for push/view links ## The default settings The default video bitrate for simple push/view links is 2500-kbps. \ \ \ By default, both outgoing and incoming video bitrates are set at 2500-kbps. This default setting and parameters are different if using [Rooms ](/getting-started/rooms.md)and explained in detail [here](/guides/video-bitrate-in-rooms.md). There are five parameters we will take a look at: 1. [\&outboundvideobitrate (\&ovb)](/advanced-settings/video-bitrate-parameters/and-outboundvideobitrate.md) -> push side 2. [\&maxvideobitrate (\&mvb)](/advanced-settings/video-bitrate-parameters/and-maxvideobitrate.md) -> push side 3. [\&limittotalbitrate (\<b)](/advanced-settings/video-bitrate-parameters/limittotalbitrate.md) -> push side 4. [\&videobitrate (\&vb)](/advanced-settings/video-bitrate-parameters/bitrate.md) -> view side 5. [\&totalscenebitrate (\&tsb)](/advanced-settings/video-bitrate-parameters/and-totalscenebitrate.md) -> view side ## On the source side ([\&push](/advanced-settings/setup-parameters/push.md)) ### The push link sets the default outgoing video bitrate target [`&outboundvideobitrate (&ovb)`](/advanced-settings/video-bitrate-parameters/and-outboundvideobitrate.md)\ Sets the sender-side default target bitrate for outgoing streams. \ \ \ The push link sets the outgoing default target to 4000-kbps. The view link doesn't need an additional parameter unless you want to override the default. \ \ \ In this case the viewer requests 2000-kbps, which overrides the push-side default target (unless capped by a max). Depending on browser/negotiation, `&ovb` can be enforced via SDP munging and may also cap the maximum bitrate. ### The push link sets a software max bitrate per stream out [`&maxvideobitrate (&mvb)`](/advanced-settings/video-bitrate-parameters/and-maxvideobitrate.md)\ `&mvb` sets a software-enforced cap per stream out. Viewer requests (`&vb`) and sender defaults (`&ovb`) cannot exceed it. \ \ \ Every view link will be capped to 1000-kbps, even if it requests a higher bitrate. ### The push link limits the video bitrate to a maximum defined value [`&limittotalbitrate (<b)`](/advanced-settings/video-bitrate-parameters/limittotalbitrate.md)\ Limits the total outbound video bitrate to a defined value. \ \ \ The incoming video bitrate will still default to around 2500-kbps but permits the viewer to increase it on their end with `<b` telling the push link to not get higher than 5000-kbps total outgoing bitrate. ## On the viewer side ([\&view](/advanced-settings/mixer-scene-parameters/view.md)) ### The view link sets the video bitrate per stream in [`&videobitrate (&vb)`](/advanced-settings/video-bitrate-parameters/bitrate.md)\ The view link is setting the target video bitrate per incoming stream. \ \ \ The view link is setting the bitrate per incoming stream (in this case 2000-kbps). So if you have a view link with three incoming video feeds: `&view=stream1,stream2,stream3` - every source is pushing 2000-kbps as `&vb=2000` and the view link has a combined bitrate of 6000-kbps. Depending on browser/negotiation, `&vb` can be enforced via SDP munging and may also cap the maximum bitrate. ### The view link sets the total video bitrate for all incoming streams combined [`&totalscenebitrate (&tsb)`](/advanced-settings/video-bitrate-parameters/and-totalscenebitrate.md)\ This is similar to [`&vb`](#the-view-link-sets-the-video-bitrate-per-stream-in) but it sets the target and maximum bitrate for all incoming streams combined. \ \ \ So if you have a view link with three incoming video feeds: `&view=stream1,stream2,stream3` - every source is pushing 1000-kbps as `&tsb=3000`. ## Mixing the parameters As doing some testing there were these results: All three push parameters cap the maximum. If you set one of these values, the outgoing video bitrate will never be higher than that limit. `&tsb` always limits the bitrate on the viewer side (total across streams). `&vb` sets the viewer target per stream, but it can be capped by sender-side limits or SDP munging. * `&vb` overrides the default target from `&ovb` * `&mvb` is a software max cap, regardless of `&vb` or `&ovb` * `&tsb` caps the total incoming bitrate across all streams ## Related {% content-ref url="/pages/V1Pj8EBxP8crFyFveJho" %} [Video Bitrate Parameters](/advanced-settings/video-bitrate-parameters.md) {% endcontent-ref %} {% content-ref url="/pages/cmIArVZ1ZIIeKoPAl7As" %} [Video bitrate in rooms](/guides/video-bitrate-in-rooms.md) {% endcontent-ref %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
