    I have a window that I shot through and then later added glass so I could put a sun in and clouds so it looks like it’s outside. My question is how to I make the masks smooth to the window pain and how do I get them to change perspective with the camera?

    I was thinking track motion, but I read on here that track motion won’t make the masks conform…

    if that makes sense…

    thanks…

    Have you considered doing this manually by setting keyframes for Mask Shape. Sometimes that’s the easiest way if it’s not a long shot, and being a window it would be a pretty simple mask shape.

    I’ve got the positions keyed, it feels like the mask is floating…it’s not smooth enough…could be my keyframing skills…, it doesn’t feel like the clouds were shot with the same camera…

    You may need to add more keyframes. It’s a little hard to tell without seeing the shot… can you post it somewhere? or email me ([email protected]).

    If you can get a good motion track on the window corners, you should be able to apply the tracking to a
    black solid layer and use that black solid layer as a track matte (Alpha Inverted Matte). You can then see through the window, and if the Sky, Sun and Clouds
    are on layers below, you will see them through the window. If there is a lot of camera movement you’ll have to compensate by moving the layers below (Sky, Sun and Clouds, maybe better if precomped) in opposite directions to the camera.
    It should work.

    For details on tracking and applying that to a layer, see the Adobe tutorial below:

    I haven’t seen the footage, but if the camera has a handhled feel then sometimes it’s easier to stabilize the footage so your window doesn’t move, do your masking and the de-stabilze the shot.

    here’s a link to a post I did a few months ago with an expression:
    De-stabilizing footage
