    I just started using AE yesterday, and am still trying to wrap my head around it. I used to do all my compositing directly in FCP, and am trying to learn to do it the "right" way now :confused:

    So I am created a TV in photoshop, and have a really long film strip type thing that I want to run behind the screen part of the TV, horizontally. I no that in FCP I would open up the nested TV psd and put the film strip behind it, and make the screen of the TV not visible.

    In AE, I am wondering how to do this. I have a feeling I would use a mask or an alpha channel, and am still trying to figure it out in AE. Any tips would be awesome!

    Hi Matt!

    In After Effects, when you import your PSD file, you should have the option to import it as Footage or as a Composition. Choose Composition, and it will import your footage as a new comp, with layers (and their transparency) still intact, similar to the way FCP handles them.

    Good luck!

    Ok, great

    Thanks for the answer. I actually just made a mask with the pen tool and reversed it, reversing it was what was giving me the grief.

    Thanks again!
