anyone know how to do this in premiere, combustion, or afterfx? I've got a scene rendered out in pics at 24 fps, but would like to re-render it at 30 fps, while maintaining the same speed. Is this possible, or do I need to re-scale my animation and re-render?

well, the simplest way to do it is by doing a 3-2 pull-down.

in this process, every 4th frame is printed twice, but to mask this effect of blatantly duplicate frames, a process called field integration is used. if it's possible, the 3-2 process can take one field from the 4th frame, and the opposite field from the next frame, and make the extra in-between frame instead of making a direct copy. it makes it much smoother.

i'm not sure how to do this yet in premiere. i haven't had to deal with 24 fps before, yet. everything's been for video. but, i'll open up premiere and look around a bit. if i find anything i'll post again.

Thanks very much Lyon; appreciate the info thus far. I'll look into it myself too.

maybe it's not that simple.

well, all i can suggest until i can ask the digitial video instructor here is to search for how to create a 3-2 pulldown and see what you find. but it may be better to adjust your timeline and rerender at 30fps.

why did you animate/render in 24fps?

Why? Because it was what I was used to/trained to do. :) On my school's equipment, we could animate/render at 24, and use a seperate piece of software to do a film speed/30 fps conversion that worked flawlessly. Oh well..

In premier if your Project settings are the correct frame rate for your images (24) then when you export select the new frame rate (30) I think that will do it.
