Applying a track motion to a mask
Hello. First of all I want to say that my English is bad, So I hope you will understand what’s my problem.
I have video over 10 second with man moving on the street. I want to remove background and make it green. So I made mask for removing background but it’s very difficult, because I have to transform mask on every frame which needs very long time. I just want to track motion to a mask. Can someone help me with this? BIG THANKS and sorry for my disgusting English. :)))) -

From your description it sounds that you want to isolate the man in the shot. Since the man is waking there is no way of just applying a track to mask – you need to cut him out Roto brush may work but Mocha will help you for sure to cut a mask for him.

mocha commits to tracking masks by default. The mechanics of mocha are such that you draw a mask/spline over the tracking area and mocha then tracks the area, bringing the mask along as it tracks the area.
