Highlight the way of passage of an object
on Feb 12, 2013 at 4:35:41 pm


I can't find how to do this (without a full roto...):

I have a simple object moving on my video (like a square : a sweeper), I want to "highlight" the path covered by my object.
(This effect is to emphantize the cleaning produced by the sweeper on a surface !)

I have no problems to track each corner of my object. In my idea I want to attach the two tracker to a thin mask (of the same width as my object) and use it in an adjustment layer.

But it's not the good way !

Anyone have an idea ? to connect tracker to a mask or a "line" brush between two point ?
