Animation twitches/jumps between Keyframes I'm currently working on my first 3D animation and stumbled upon this:
Blender animates the movement between my keys, but here and there there is weird twitching between them.

It's like there are invisible keys that the body parts just jump to instead of smoothly animating.
My F-Curves are set to Bezier (even though I tried Linear without any changes) and I used the middle mouse button to go down in the timeline to see if there were any keys I missed.
I used the blender rigify addon for the armature.
Blender 2.91
The Project:
If you activate foot_ik bone &quot;Toggle Pole&quot; button will be shown in the
side bar. - tetii

That was it! After toggling I saw that there was something seriously wrong with my legs. I deleted the key-frames and redid them, now everything works fine.
Thanks.
