Currently the limits for vmixcall is 720 at 2500kbps (unless you are vmix to vmix). Technically, 1080 is possible with WebRTC - and so are higher bitrates, so I would love to see a few more options to use 1080 and perhaps double the video bitrate to around 5000. These are possible on other WebRTC platforms - but not many have the simplicity of vmixcall. I understand that pushing the boundaries may lead to issues with those with limited bandwidth, but i'm finding a lot of the time I have everything set to max, and feel that I would like to go a little higher.
