output animation all jumpy/jerkey in wrong order...

[rfollett]

I have logged this in animation forum but not sure many people look there!

Working with 4.0.74
A client sends me a KSP file. I import ok.
I then setup a simple animation.
The frames are output all out OK, in correct order but the animation (Quicktime MOV) is all wrong. Jumps around like frames are all in the wrong order?

Have you seen this before?

Thanks

Can anyone help with this issue?
