In the graph editor there is a nice straight line in between the two keyframes, yet it deviates from the y-axis (in the animation not the graph)

Thanks for the response. My situation is a little different than you described. The goofiness is happening between 2 key frames in which there is a change in value. The animation starts correctly and finishes correctly but even though it is a linear movement, it is doing it own swooping and scaling in between, just making up its own movement. This is entirely frustrating and nonsensical.

It is just a position movement (with rectangular mask movement as well) on the X axis. For some reason around the middle of the 2 key frames it drops on the Y axis.

Thanks a lot. What I am experiencing isn’t exactly what you described but I’m sure they are related. I will check out your links, try what you said tomorrow and post back.

Thanks again for the quick reply!
