Motion Vectors, Camera translation and animated FOV

[henning]

Hi!

So I'm getting slightly strange results from doing motion blur in post with an animated camera thats also changing its FOV.
Has anyone figured out how to (mathematically correct) tweak the Velocity Element to compensate for the FOV-change in every frame? Can it theoretically be done?

Perhaps you could motion-blur the Z pass in a separate comp before using it for the focus?

Oh no, I had "ignore z direction" checked! Thank you!
