What do you think about this one?
GM was filmed in 120fps.
When trying to interpolate the 24p version of Billy Lynn, I noticed the way the movie itself was shot lent itself to being shown in higher frame rate.
I also don't know if the frame rate that it was shot in (192fps) had something to do with the motion in 24p.
Trying to interpolate other war movies, like American Sniper, Black Hawk Down, Green Zone, did not result in a acceptable outcome.
A movie with fast moving objects, like the F&F series, while it does improve fluidity during car chases, it ruins the cinematic aspect. The first one in particular looks more like a proper movie, while the latter ones could work with CFI/being shot in HFR (only tested 1 and 2).
LE: just tested stealing the vault scene in Fast Five, and the CFI improved the visual aspect.
LE2: seems like Mad Max Fury Road also benefits from CFI.
The aspect that's trying to be improved is not (just) judder, but making the image smoother, more fluid. It doesn't work with everything. Some scenes may look great, others not so. Since it's ackward to enable/disable/change type of CFI during the movie, you're stuck in one mode, so a compromise has to be made if enabling CFI or not.
It wouldn't bother me if 24 frames were used in some scenes and 60/120 in others.
