Using Premiere Effects in After Effects (Colour Balance)

    Is it possible to use the 'Colour Balance' effect from Premiere 6.5 in After
    Effects 4.0?

    ie. in Premiere, the colour balance effect lets you change the R,G or B
    values within 0-200 range.
    In After effects it gives you Shadow, Midtone, and Hilight R, G & B values
    (within -100 to 100 range).

    I want to use the simpler, Premiere version of the colour balance effect in
    After Effects.
    (The reason I'm using After Effects is for the mattes with keyframable
    shapes which isn't really possible in premiere).


    - If it's not possible, is there a way to export just the mask's Alpha
    channel in a format that won't be uncompressed RGB (file size to big) but
    not DV (because of problems with not enough chroma sampling) - so I can use
    it in a video track in premiere and chromakey the masked part.

    I don't think so. Premiere supports certain AE filters, but it doesn't seem
    to go the other way. However, AE supports certain Photshop filters. If
    there's a good Photoshop color corrector that you like, you should be able
    to get it to work.
    Use the Quicktime Animation codec. It supports Alpha channel and is lossless
    at 100%. This way, you don't have to export the Alpha channel as a mask.
    Keep it in the footage.

    If you *do* export the Alpha as a mask, use the HuffYUV codec. It's usually
    about half the size of "uncompressed" and looks as good (lossless).

    I assume you are using the color correction to replace what the key might be
    taking away from the remaining footage? If so, you could also export the
    whole thing with Alpha from AE and perform the color correction in Premiere
    (but then the whole "taking the simpler route" is out the window and you
    might as well just use the AE filter).

    Yeah, that can be a problem in Aftereffects. You almost
    get too much control sometimes. A couple things you
    can try are curves or levels. They both default to controling
    the gray-scale, but you will notice that there is a little box
    at the top that says "RGB". If you click that box you can
    select RGB, Red, Blue, Green, or Alpha. If you select any
    of the channels you get to adjust that channel individually.

    Grabbing the button in the middle of the levels pallet, or the
    middle of the line in curves will give you gamma adjustment.
    While grabbing the nodes at the end of the lines in either will
    allow you to adjust the peak white or black (depending on the
    end you choose).
