Jumpy can be a problem with the codec used. What format did you save the animation to and which compression codec?

You could try converting it to another codec.

I'd love to see the animation, by-theway, and try converting too. Do you have it as a numbered image sequence? or AVI?

Did you do it on a Mac or PC?

When you slowly scrub through the animation in a movie player like Irfanview do you see any jumping forward or back or anything abnormal indicating there's a rendering problem with camera moves etc or do the frames look just about right in sequence without erratic moves frame to frame?

Note also that some movie players can be configured for full acceleration, but sometimes it's better to try without, or if there's a problem in your graphics card's video driver, or a spyware that steals frames to an IP address it will cause interference like stop and go jumpiness. on and off.
