You must have a really beefy system if you can capture 960fps!
Revision’s Reelsmart motion blur can add blur to any framerate. it’s used for animation and re-blurring green screen objects.
It’s possible that you’re just seeing repeated frames of no motion which would appear as stutter because there’s only so many discrete frames that the game engine clock uses. It’s also possible that the recorder isn’t accurate in its fps information versus actual targa dropped frames.
And finally the bug thing. In both Cs3 and Cs4 you can’t interpret image sequences or create any compositions larger than 99 fps. I know, because I use this averaging trick to smooth out motion from timewarp interpolating.
In a nutshell, use one of these 3 options.
1. live with 99fps frame blended then decimate to 60 or 30 fps
2. use avisynth to decimate
3. get reelsmart motion blur
