Poser 6.0 jittery animation

Simple down on hands and knees anim with back and forth rocking motion (Yeah I know! Don't ask. heehee).

Used 100 frames at 15 fps, used break spline on 2nd keyframe and also used inverse kinematics on all four limbs. Inverse Kinematics makes it simple, grab and move hips back and forth, head up and down, keying every 10 frames. Exported to BVh and uploaded but the arms and shoulders are distinctly kinda vibrating. Looking back in Poser and it is doing same thing there. Any suggestions?

I was not be albe to follow your trouble. Can you explain what you did step by step?
Refer to "The usage of Inverse Kinematics" on the Animation Guide.

Actually I figured it out. I had been lazily moving the hips and head from the side. This was actually twisting the shoulders some. That was translating into unwanted movement in the arms. Now I have learned to use the memory dots and carefully pan around after a movement checking back and forth until all is perfect between the two keyframes.

As a side note I have also used AVimator and Daz. OMG AVimator rocks and hats off to him for selflessly putting so much work into a product for others to use and enjoy. Hope this brings many more good animations into SL. AVMator is much easier to learn the fundimentals with.

I will continune to use them but also slowly learn and grow with Poser. SLOWLY learning the advanced tools which once learned become indispensable.

Aha, you soluved it. Congrats.
