I frequently need to record the screen and edit it into a demo video.
The best software I've found so far is OBSproject.com, free, open-source, very flexible streaming and screen-recording software.
I would kill to be able to record at a higher resolution (ex: 4K) than my physical monitor (only 1080p) and then zoom in losslessly when editing.
Any wizards out there aware of a way to do this? Would be a giant help when creating these software demo videos! If the answer is another capture software or some FFMPEG magic, I'm down.
p.s. I have run across the Nvidia setting "DSR Factors" but, when testing this out, looks like it is a LOSSY UPSCALE, not really 4k.

证明Nvidia DSR因子确实可以从1080p显示器进行真正的4k录制。
我必须确保DSR设置为4x，然后在Windows“更改显示设置”中将分辨率设置为3140x2160，然后重新启动计算机，最后在OBS中将视频输入/输出分辨率更改为3140x2160。
