I made a project file for you that is setup to maximize the smoothness but it will probably have some artifacts. Read below how to remove in exchange for quality of motion.
It’s a good idea to never warp lower than 50% or you can start getting artifacts easily. If you need more quality, increase the vector amount. Make sure extreme filter is on too.
Unfortunately, going from a lower fps to a higher fps is actually harder to do because you have to warp 10x more. So you will have to choose between smoothness and artifacts.
You can play around with the global and local modifiers(detects moving blocks and smooths the tweening), the vectors(motion detection threshold) and filter extreme(high quality). The main thing that will determine your quality will be how much you slow down the video. If you warp down to 18%, you’ll get the maximum
possible smoothness, but you’ll probably get some artifacts.
Simply determine the “start” comp fps and divide by 99 will be the number for timewarp speed and timestretch. I strongly recommend trying out different timewarps higher than 18%, it will make artifacts a lot easier to manage.
I also forgot to mention that you have to precomp the footage so that AE will see all the footage and not truncate the “23.976 output final” comp.
(fyi) the original reason I put the 29.97i into a 59.94 is because timewarp can’t see fields, so you have to turn each field into a whole frame that gets warped. It’s what the engineers said you have to do for better quality But you don’t need to do that for non-interlaced.
