4K is a great way to get extremely high quality video. However, there are reasons not to use 4K in some cases, and we've chosen not to rush shipping 4K in Camo.
When streaming, it's best to tell Camo to provide video in the resolution and format most likely to be used by the apps you're running.
Video conferencing apps such Zoom and Meet do not stream in 4K: consequently, if you provide them a 4K video source, they will have to significantly downscale it on your computer in realtime. This is a much bigger jump than going from 1080p to 720p, and feeding your 720p video-conferencing app a 4K video will:
Look worse for other people on your calls
Give your computer more work to do, making it hotter and slower
At present, Zoom will almost never use more than 720p, and Google Meet won't go over 1080p.
Additionally, whilst many iOS devices are able to provide 4K video, this places a significant workload on both the iOS device and the receiving computer, which can cause slowdowns and generate heat. We do not recommend using 4K on older equipment.
Being able to get webcam video in the right resolution for your streaming service is a significant benefit that Camo has over dedicated webcams, which dumbly send whatever native resolution they support all the time.
