I've created an animation in Inventor 2011. I've played around with settings and file types and have seen that the following criteria give me what I'm looking for:
* 75% AntiAliasing, Fully uncompressed avi file, at 25 frames per second.
I tried this for a 3 second clip as a test and it looked and played great.
The actual length of the video is 36 seconds though and the file is 2.9 gigs and won't play on my computer.
