    >If that’s not separate code base, what is?
    It’s a different compile of the same codebase, using a different compiler and a different target.
    CINEMA has an own abstraction layer, very much like an own OS that allows for complete independence from the host OS.

    If you can tell me how Motion as a 32 Bit app with a GUI can use more then 4 GB i might be able to give you an answer. In Apples own documents given on this it is clearly stated that it is not possible to have a 64 Bit app with a GUI on 10.4.

    >BTW, why doesn’t Cinema use more than 2 gigs of RAM? Thanks!
    It does, it’s just that Windows XP does not allow an application to use more then 2 GB by default. The /3GB option in the boot.ini changes this limit to 3 GB. On OS X this border does not exists and CINEMA can use the complete 4 GB that a 32 Bit OS allows.

    Again, tell me how Motion does it.

    This is what Apple tells on this
    > Got boatloads of RAM installed in your system? Motion 2 can use it.
    > With Mac OS X

    Thanks for answering the questions.

    I don’t know how Motion 2 does it. It’s clearly a 32 bit binary, but it can utilize more than 4 gigs of RAM for things like RAM preview, which is displayed in the main application to the end user.

    In this case i have no idea why Apple utilizes a technique to do this for their own products without offering it to other parties. Either there are some still unknown facts on how Motion 2 does it without using 64 Bit in the Interface or the available options for developers outside of Apple are different to what they use internaly (which i doubt).
