I agree. All we can do right now is speculate till we see the shot.

I haven't actually tried a legit matchmove with a lot of motion blur (usually, given I have one computer and stupid short turnaround times, and very little experience, I do tricky directional post blurs for my 3D matchmoves instead). And, of course, the closer the object to the camera/the slower it moves, the less it'll be affected by this particular issue. Anywho, I've really gotta get better at matchmoving. Just got a shot in today that I had to opt for a 2d track and scaling the values to get the shot because I just don't have time to relearn boujou
