Here's a comparison of a 60 frame per second render (top) vs a 24 frame per second render. (from iClone's native renderer)
With 60fps, there are 60 equal intervals.
With 24fps, the intervals are not equal - the cube jumps according to a pattern (sometimes 3 intervals, sometimes 2)
This maybe the reason native 24fps rendered outputs don't look very smooth - although the 'average' distance moved is the same as the 60fps, the 'momentary' increments aren't uniform like the 60fps.



Rendering out of iClone at 60fps in PNG and then importing into a non linear editor for setting the *final speed* - gives the best results.
The NLE has 60 frames to choose from so if you want 30fps - it will simply discard every second frame. If you want 24 fps - it can make the best choices from the 60 available frames.

Please be patient with me ..... I don't always 'get it' the first time 'round - not even the 2nd time! :(  - yikes! ...
