Animation glitch

Hello… I have a very annoying problem… and it’s difficult to explain.

I was animating one of my characters when, watching carefully I realized that it was making little jumps throughout the all the animation, kind of like shaking, like glitching.

All of the other characters are functioning normally.

I thought it could have been the curves, but no, checked all mi animation keys and there is nothing there. can some one give me a hand on this please?.


do you have a lot of constraints – track to’s and IKs and stuff? Sometimes they don’t refresh correctly

or funky knee/elbow pole targets? they sometimes tend to let the legs/arms jiggle when the pole targets are too close to the joints they control.
