When should I use 4K video?
我什么时候应该使用4K视频？
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.
4K是获取极高质量视频的好方法。但是，在某些情况下有理由不使用4K，因此我们选择不急于使用Camo运送4K。
进行流式传输时，最好告诉Camo提供您正在运行的应用最可能使用的分辨率和格式的视频。
诸如Zoom和Meet之类的视频会议应用程序不会以4K格式进行流式传输：因此，如果您向他们提供4K视频源，则它们将不得不在您的计算机上实时大幅缩减其尺寸。与将1080p转换为720p相比，这是一个更大的跳跃，并且为720p视频会议应用程序提供4K视频将达到：
在通话中让其他人看起来更糟 使您的计算机有更多工作要做，从而使其变热和变慢
目前，Zoom几乎不会使用超过720p的分辨率，而Google Meet不会超过1080p。
此外，尽管许多iOS设备都能够提供4K视频，但这在iOS设备和接收计算机上都增加了很大的工作量，这可能会导致速度变慢并产生热量。我们不建议在较旧的设备上使用4K。
能够以适合您的流媒体服务分辨率的网络摄像头视频是Camo相对于专用网络摄像头的显着优势，而专用网络摄像头始终会发送他们支持的原始分辨率。
