Am learning and gnashing teeth at the same time.

In P4/5, I have a 30 frame animation where I have a figure jumping in the air and landing. I set beginning, middle and end pose. Poser 'graciously' sets in-betweens but elements (feet/ hands/ arms) will wildly fly out in an attempt to fill in the gaps.

I'm starting to play around with the different types of interpretation (Linear, Break Spline, etc.) but am unsure where to begin.

Do I:

A. Break the spline after a pose or before?
B. Use Linear interpretation to avoid these wildly over-emphasized in-betweens?
C. Break down and weep?

Any help would be appreciated.

Best,

JG
