Hello guys,

I need some help with tracking. I have a shot where an object is entering the scene from one side and exiting on the other. I need to replace the banner on that object. Right now I am using 4 corner tracking. The problem is that as soon one corner of the object exits the frame, that tracking point goes crazy. Now what do I have to do in order to have a smooth motion of the banner. Do I have to move those tracking points manually as soon they go crazy?

Thanks in advance

cheers

Either you're going to need to hand animate the points once they leave frame, or else you're going to have to sort of cheat it and switch your tracker from Absolute to Relative once your tracking point leaves the frame and grab a new tracking point that is still in frame, but is exhibiting similar motion.
