[Interest] Do Camera.videoRecorder options matter?

[Jason H]

Well file size is the real issue. Which is governed largely by those factors. If there was a way to do it with bitrate alone, I would entertain that.

That is interesting to know. I was initially trying to record using Camera.CaptureViewFinder, but got a message about it not being connected. When I changed it to Camera.CaptureVideo, then I was able to record. But it seems that given the names of the properties you mention, there is some hackery where the video frames to the viewfinder are being recorded?
