&optimize

Video bitrate reduced when the video is not visible in OBS (not active in a scene)

Viewer-Side Option! (&view, &scene, &room)

Options

Example: &optimize=1000

Value	Description
(integer value)	value in kbps
(no value given)	600-kbps
0	disables the video track when not considered visible in a scene (OBS)

Details

&optimize reduces the video bitrate to 600-kbps when the video is not visible in OBS (not active in a scene). This is mainly there to help with reducing load for OBS and for guests. It can take a few seconds for the bitrate to ramp back up after it becomes active again.

Consider using &optimize=0

As of VDO.NInja v26, &optimize=0 will make it so that a remote guest will not connect to a manual scene (&scene=1, for example) until the director manually adds the guest to the scene.

What this means is that you can have each guest assigned to their own scene (eg: 1 to 8) and have each be treated like a &solo link, so long as you never add more than one at a time and wait for the previous guest to disconnect.

Normally, otherwise, if you had 8 guests in a room, and each had their own scene, without &optimize=0 set, each scene would still have each of those guests connected; so each guest would be connecting 7 additional times, without it being needed. This reduces stress on the VDO.Ninja servers, but also avoids connection issues when there are perhaps dozens of users in a room. While adding a guest to a scene this way takes about a second, for the connection to be made, once added you can remove and add the guest back quickly, as they stay connected at that point. &optimize=0 will also, as before, mute the video/audio tracks, lowering the video/audio bitrate of those tracks to 0, when not needed.

Pausing and resuming a video/audio track does take a split second to do, and it may result in temporarily low quality video after being enabled, it you don't intend to add/remove guests frequently to a scene, it is highly recommended you use it. The only time you shouldn't use &optimize=0 is perhaps when you have just a single group scene, and you prefer speed and quality as you add/remove guests to the room. This might also be the case if using the &activespeaker mode, where guests are hidden and removed when not active speaking.

This does not work with iPhone-sourced video streams.
