    hi guys…
    i have a little problem on this project i’m doing for work…and i MUST learn how to resolve it 🙁
    can ya’ll help?

    here’s the deal:

    we had to do this slowmotion shot of this guy.
    we bought TWIXTOR (by the way, the plug-in rox).
    anywho…the general rule is NOT putting the plugin directly on the clip. u have to make a SOLID, then put the plugin on the solid and assign it to the clip.

    so with that being said and done, i have the clip of the guy and a clip of the same thing but it’s a matte so it can just be the guy.
    i also had to obviously put TWIXTOR on the matte as well so it could follow the original clip.

    so now that i got the slowmotion guy with a black background, how the heck do i put something in place of the black background?

    here’s a pic of what i’m looking at:

    see….i have the clip and its solid, and the matte clip and its solid.

    NOW i gotta put stuff behind the guy.
    the highlighted layer in the picture is a layer i wanted to put behind the guy just to see if it’ll work, but i couldn’t figure out how to do it.
    it’d either go behind EVERYTHING or in front of him.

    is it a certain way i have to set the “MODES” or something?

    please let me know, someone…it’s really important.

    thanx so much,

    _chris

    So it’s late, and I’m not quite sure I followed everything… but can you do some sort or precomposing and then set the mode for the pre-comp to something that will drop out the black and place your backround under it?

    And if you’re worried about the guy being somewhat transparent, you could always turn a copy of your guy footage to a solid white and use it as an alpha matte instead… right?

    Maybe someone else has a better idea.

    peace,
    Michael
