Hey guys,

I'm having some weird problems. Whenever I rotate my image on the Z-axis (while having 3d mode applied), the image is distorted. I posted some pictures below. Does anyone have any idea on how to fix this?

I see that the comp's resolution is 1280x720, which is 16x9 in SQUARE pixels. But the comp has a pixel aspect ratio of 1.33. You probably made comp-sized solids, so they too have a pixel aspect ratio of 1.33. But when you rotate them, they're deforming.

The fix: work in square pixels.

I'm still not sure if I totally get how the rectangular vs square pixel dilemma works, but I managed to get it working. I kept the 1.33 aspect ratio for the comp and the footage itself, but changed the solid's interpretation to square pixels. After switching the pixel correction on it all looked perfect.

Thank you for your advice Dave, it was much appreciated!
