People beware, I'm opening the framrate discussion again.
I looked atdifferent footages, both recorder and animated/rendered.
I also took into consideration how our eye/brain processes images.
When we blink we don't see dark and when we move our eyes we don't see blur. Because our brain has a remarkable trick:
It shuts the eye off and repeats previous images. it so to say "holds on" to previous frames.
And similar it is to standard image processing. We might not get information from the eye 60 times a second, but we do see in around that frequency (which is why good fluorescent lightbulbs and monitors are faster than 50Hz, we still see the flickering).
And when talking about VR, I think 50/60fps is important. But when recording, the 24/25/30fps is still ideal because of shutterspeeds, it also imitates how we actually SEE movement: blurry.
I realized that when I was recording at SPECIFIC apertures, so I set the shutterspeed to 1/200 for some of the footage and in one clip, two guys on a motorbike where driving past right in from of the camera. While slow movements, like people or trains in the distance seemed normal, this fast movement seemed hella unnatural, because the bike was in the clip for only a few frames, but hella sharp.
Similar, in the 48fps Hobbit, slight camera-jittering was really noticeable and gave a cheap, home-made feel to the motion, while the 24fps material looked smoothed out.
So I think for VR, RL-Video needs to record at 60fps, somehow blend the frames to downsample to 30fps to get a smooth blurr, and then write the video at 60fps.
Animated Video can just render at 60fps and add motion blurr to objects.
Thoughts?
