Optical flow and resizing crash

I have been thinking this thru, however, having two differently sized images in sequential frames is an invalid scenario to calculate optical flow, and the user probably wants to know about this in the form of a warning/error, which is already happening.

What would be the ideal solution @azeno ?

Long time ago. In the forum thread I wrote that vvvv beta also crashed completely, that was probably our main concern. I think I also wrote that the exception on the optical flow is fine.
