This the first time that I'm departing from a basic 29.97 fps scenario and delving into different frame rates. I need some confirmation from professionals that have experience with it. Pardon me if my questions seem foolish.
Here's what I've got.
I've created a number of animations, all CG, all in AE, no footage, and I need to composite them together at different speeds, but I ran into choppiness when applying time remap and stretch that frame blending didn't fix.
Q1: If I render the animations out at 90fps, drop them into a 29.97fps comp and time stretch to 300%, will I essential have every frame played out over 3x the time?
Q2: If I choose to time remap at varying speeds within the same animation, will I run into the same choppiness?
I think I know the answer without asking it but in this case I don't know what I don't know, so any advice from the experienced would really help. I've got to crank this one out fast and I don't have time to experiment.
Thanks to the COW in advance! You've never failed me!

It all depends on the ORIGINAL FRAME RATE of any video footage in your 90fps animations, if there is any. Got video in 'em? You're opening a rat's nest of problems. No video in your 90fps animations? You're good to go!
"Q2: If I choose to time remap at varying speeds within the same animation, will I run into the same choppiness? "
You most certainly will encounter choppiness, especially if you VARY the speeds, and most especially if those speeds are something off the wall, like 247% or 16.2%. You'll see less of it, but it will still be there. You'd want to use AE's Time Warp feature to minimize it.
