I think it's a bit unfair comparing a live action film with what is pretty much all animation.
And also, I didn't notice the weirdness in this film but noticed lots of 'stuttering' pans in the 2 last Matrix films. Is this a similar sort of effect?
Film runs at 24fps . If certain scenes in OUATM were shot30fps there are a couple fo options to get it on film. Leave it alone in which case it will look slowed down.
Cull 6 frames out of it every second in which case it will stutter. Remap the entire action from 30fps to 24fps using motion analysis to basically build you new frames by warping/morphing (using tracked vectors) the original frames to give new frames which portray the same action in the same time with less frames . ( although this sounds far fetched it is actually quite common practise these days to do speed changes without introducing stutter)
There is plenty of live action in AOTC to compare with OUATM and AOTC looks a lot better if you ask me.b This could be down to a number of things , better lighting , higher spec capture format and even less craziness at the final grade.
Stuttering pans in the Matrix could be down to a number of things , if it was non-effect shots then it could be down to the shutter speed interacting with the speed of the camer move ( does happen with any progressive capturing system unless you up the frame rate: temporal aliasing in effect) if its effect shots they might have decided to more closely match the optical flow generated shots in the original film which have a slight jitter to them ( this can be rectified by introducing more appropriate camera motionblur but they may have preffered the otherworldly sharp look with no moblur.
The lack of motion blur is also the same mechanism that makes the live action pans look stuttery , dropping the shutter speed and introducing more motionblur fools the eye into seeing smoother action even though the relative time and postition of the frames relative to the action hasn't changed.
