    Okay, due to a bit of bad planning on my part, I’m in a bit of a jam. I have this scene I did in AE:

    And this rough stop motion scene:

    Now, my goal is to some how amalgamate these two scenes together. I’d like the camera to pan down through the trees, and then have the cabinet shuffle in through the front door.

    So, I essentially need to somehow meld this angle
    IMGP1128
    And this angle together
    layer

    Im pretty sure I’ll just have to cut out the cabinet for the last bit when it comes through the door.

    As for the rest, I was thinking of doing some kind of 3D skew?

    Any suggestions and/or ideas would be greatly appreciated.

    if you have one frame of the stop motion scene w/o the cabinet, you could try difference matte on the stop motion scene, setting it to use a separate still of the stop motion scene w/o the cabinet.

    if you shot this with a still camera, i think you’ll have a good shot at pulling this off.

    It is, in fact, in a series of stills made into a quicktime.

    Are you saying to set the stop-motion scene to difference and try to lay it over the comp? I do have a few frames without the cabinet in it. What is it that I’m doing with it?

    no, not the blending mode… there is a and effect in the keying effects called difference matte. what it does is looks at the pixels from one image/footage and removes any similar pixels from the image/footage that it is applied to. so if your shot was locked down well and your lighting stayed consistent, you may be able to use this effect to remove the similar pixels from the footage with the cabinet, by using a still shot that does not have the cabinet.

    so bring your stop animation footage in to a comp and bring in a still w/o the cabinet (you can hide the still), then apply difference matte to the stop animation footage. set the still shot as the difference layer, then you can make tolerence, softness and pre-blur adjustments as needed to key out the cabinet.

    ohhhhhhhhh! okay, ha ha.

    I didn’t catch the difference “matte”. Sorry, more coffee is needed.

    That’s a good idea. I’ll try it out.
