I found if I nudge one of the keyframes just a tad in X, the flipping goes away. It seems that if I have two keyframes with only a difference in Y (on a 3d layer) I get flipping.

I'm not sure how using a null is going to prevent the gimbal lock. The layer just has a few keyframes on it. I tried copying the keyframes over to a null and it is twisting as well. Maybe it just can't handle keeping the roll intact when traveling in Y.

Byron,

 

I too always use nulls for controlling 3D camera – it’s just not reliable without nulls especially auto-orient layers.

A film is – or should be – more like music than like fiction. It should be a progression of moods and feelings. The theme, what’s behind the emotion, the meaning, all that comes later.
