As part of a video promoting a companies video department, they want to show they use green screen technology. They are having a presenter speak to camera with green behind them, and then when she clicks her fingers, a photograph appears as the background instead. However, the green screen behind them has some creases on it and they would like to replace it with a matte green.
I know how to do this using FCP and chroma keying, but I want to get in the habit of using Motion. Is there a way of using Motion Tracking to select the presenter and delete everything else, then adding a layer of matte green behind them?
P.s I have never used the Motion Tracking before, so may need it quite step-by-step if this is okay.
Thanks in advance and I look forward to suggestions
You woul not track this. You just need to create a mask that would be slightly bigger that the areas you want to cover, then you would animate the mask. This can be done every 5 to 10 frames depending on how much movement is in the shot than you would use a keyer to remove the rest of green screen. After that export your footage to FCP using apple pro Rez 4444 or animation codec with alpha.
