Yes, cinematographers do vary the shutter angle for artistic purposes, but that just confirms the fact that the amount of motion blur present in a film is a deliberate artistic decision rather than a side effect of using an "antiquated" frame rate.
As for downsampling, I believe your math is off. 120 fps at 360° means each frame is exposed at 1/120s. Conforming that to 24 fps gives you the same exposure duration per frame (you're just throwing out 4/5 frames), so you're effectively at a 72° shutter angle - less than half of what's considered "normal".
- mrob 7y agoI only said that 144° effective shutter angle is possible, not that you can achieve it by deleting 4/5 frames (which does give you effective 72° shutter angle). You actually need to delete 3/5 and blend 2/5 (and the 360° shutter angle of the 120fps source needs to be accurate enough that you don't see the join).
