Your screenshots aren't labeled so I don't know which is which.
I also don't understand the problem you're having. You previously stated you were getting no VRayVelocity channel but your last screenshots imply both are returning colors.
Only thing I can think of, regarding your last screenshots, is that it's possible velocities in the VRayVelocity channel are not being calculated at the correct time scale. The VRay SDK is a bit confusing in that regard and once I confirm the problem you're having I can talk to the devs about it.
