Kronos or RSMB ?

[stevesideas]

What do you guys think ? I currently use RSMB. I'm trying to motion blur a scene that has a camera zooming in plan view onto a car but the prediction looks very strange ending up with odd results.

I tried using velocty RSMB but I get artifacts around the car. Maybe I need to separate the car from the main scene ?

I'm very happy with the detection that kronos does, it never fails to surprise. worth giving the trial a go, we have a few licenses here.

You do need to separate them, even with kronos, you would have to provide it some alpha (mask) for the car. With zooms though, no motion vector will do good job. 3d mb only.

RSMB for us. With VRayVelocity it looks great and performs even better.
