Pans looking juddery no matter what you do in 24 fps is a very well known issue. Motion blur’s ability to help (using the 180-shutter rule) is quite limited, and you can also reduce it somewhat by going very slow (using the 1/7 frame rule), but there is no cure. The cinematographer cannot fix the fundamental physical problem of the 24 fps framerate being too slow.
24 fps wasn’t chosen because it was optimal or high quality, it was chosen because it’s the cheapest option for film that meets the minimum rate needed to not degrade into a slideshow and also sync with audio.
Here’s an example that uses the 180-shutter and 1/7-frame rules and still demonstrates bad judder. “We have tried the obvious motion blur which should have been able to handle it but even with feature turned on, it still happens. Motion blur applied to other animations, fine… but with horizontal scroll, it doesn’t seem to affect it.” https://creativecow.net/forums/thread/horizontal-panning-ani...
Even with the rules of thumb, “images will not immediately become unwatchable faster than seven seconds, nor will they become fully artifact-free when panning slower than this limit”. https://www.red.com/red-101/camera-panning-speed
The thing I personally started to notice and now can’t get over is that during a horizontal pan, even with a slow speed and the prescribed amount of motion blur, I can’t see any details or track small objects smoothly. In the animation clip attached to that creativecow link, try watching the faces or look at any of the text or small objects in the scene. You can see that they’re there, but you can’t see any detail during the pan. Apologies in advance if I ruin your ability to watch pans in 24fps. I used to be fine with them, but I truly can’t stand them anymore. The pans didn’t change, but I did become more aware and more critical.
> 60fps will always look like cheap soap opera to me for movies
Probably me too, but there seems to be some evidence and hypothesizing that this is a learned effect because we grew up with 24p movies. The kids don’t get the same effect because they didn’t grow up with it, and I’ve heard that it’s also less pronounced for people who grew up watching PAL rather than NTSC. TVs with smoothing on are curing the next generation from being stuck with 24 fps.
