Re: Using a clean frame instead of greenscreen

hey good question! ive been experimenting with this today and there are a few good plugins you could use. First i would suggest motion stabilizing your footage if you haven't already and line up your clean plate frame. Use the difference matte effect in the keying section of the effects panel. IF you want to generate a clean plate throughout your footage, i might suggest getting the boris continuum 5 plugins pack and it comes with a great motion key plugin to extract moving objects from your footage. Use this o generate a clean plate along with the remove noise and grain effect applied before it. copy and paste the remove noise and grain effect to another copy of the footage without the motion key plugin and you should have two perfect candidates for the difference matte plugin. Make sure you precomp the motion keyed footage before applying the difference key to the other footage because the difference key cannot 'see' effects. then you can use this as a track matte for another piece of footage if you want to keep the grain. I would suggest rendering this out before using it in a project because it will take a very long time to render.



Let me know how this goes and if you made any changes because my method isn't perfect but it should work.
