How do I go about creating a Clip Alpha Matte in Motion 5?  I have the Quicktime clip and Quicktime clip wipe matte.  Can I invert the wipe matte? Not sure how to go about that and save outside of motion.

    First, if you want an alpha channel, you'll have too export as ProRes 4444, and in the export window set "Color" to "Color + Alpha" and turn on "Premultiply Alpha".


    Not sure what you mean by the wipe matte.  Where are you getting it from?  No clue what the Wipe Matte is in Motion 5.

    I'm sorry, I simply do not understand what you're doing, but let me try.


    First, are you making a transition for FCP 7 or FCP X?  This is the Motion "5" for FCP X forum.


    You seem to be trying to make a transition for FCP 7, using Motion "4", that requriered all three elements.  You should post in the "Final Cut Stuido" section.  Basically you can do an invert of your wipe matte and export that as a QT movie.


    If you are trying to create a transition for FCP X in Motion 5, that is quite simple and I can help you with that. 


    But let's clarify what versions of FCP and Motion you're working in first.

    OK, let us clarify this first.  In FCP X with Motion 5 we do not do things the same as with FCP 7 and Motion 4.  Totally, 100% forget everything you know about making alpha transitions for FCP 7.


    You don't need those three elements like you did in FCP 7.  In fact, it isn't going to help at all.  Use mask shapes, cropping, etc, in Motion 5 to do it all.  Much more simple.  You're going to work a whole different way now.


    Here is a simple wipe transition I did specifically for my students to learn with.  Check it out and let me know what questions you have after following the included instruction.  It comes with a finished project file, and an instruction document showing how to build it from scratch.

    Motion 5 project files are not compatible with FCP 7.

    No clue about Compressor 4.


    Working with FCP X is totally different, totally new, and faster and easier than 7, once you learn it.


    I'd not bother trying to pull transitions over from 7 to X.  It is going to be a ton of PITA work, if they even work.  Simply building them from scratch with Motion 5 is very easy.  Thrid party plugins for X are way cheaper than they were for 7.


    If you do want to pull "transitions" form 7 to X, do it in Motion 5.  Start with a "Final Cut Transition" template to pull all those QT files into and work from there.


    IMHO, plugins are not a reason to not move forward.
