I apologize because I guess I’m not understanding you. From 1:03 until 1:11 in the video I posted I am clearly moving the bezier handles of the offending keyframe, so I’m not sure why you’re telling me to zoom in so I can “get a good grab” on the handles. I’m clearly not having any issues in the video with “getting a good grab” on the handles, so what would I gain by zooming in?
Further, after I grabbed and moved the bezier handles, the only thing that changed about the unwanted movement was the angle of the movement as shown at 1:12.
I should also mentioned that I did try grabbing the handles and moving them until they they were essentially over the keyframe (which basically makes it linear movement and defeats the entire purpose), and the unwanted movement was still there and was basically unchanged.
So I have no problem grabbing handles and manipulating those handles doesn’t really change the unwanted movement at all, so what am I missing?
