I am new to motion and I have been trying to blur the license plate on a moving car. I anylized the motion but after that I am lost. I am also wondering how to blur out a logo on a tshirt and hat. I am on a cruise ship and the Internet is to slow to download QT tutorials and the apple supplemental documentation does not work either. No After FX here either.
The down and dirty explanation is to place two copies of the clip into your sequence, one on top of the other. On the lower clip add a gausian blur and on the top track at a matte over the license plate or t-shirt logo. Do a motion tracking on the matte to follow the car or t-shirt. Feather the edge of the matte a bit and you should have a good effect.
