FCPX Effect from Motion with two sources

Sorry, not sure I understand what you mean. Are you asking if you can create a motion effect for FCPX with two video sources? Can you explain what you are trying to achieve?

Yes. Just add a drop zone (Object menu or Shift-Cmd-D), it will automatically publish an image well to be used in FCPX. Create your effect and save it. When you are in FCP X, drop the effect on your clip in the timeline, then apply the second clip to the drop zone image well in the Video Inspector.

Hey Leo,

OK, with the added detail of what you are trying to build, I've got a few ideas.

If it's a fake anaglyph effect (looks like a Red/Blue anaglyph, not really 3D)
-Create a new Motion effect.
-Clone the Effect source layer twice.
-Apply the channel mix filter to each layer. Set the top layer so only the red-red value is at 1. Don't worry about the alpha.
-Set the second clone layer to red-red zero and both the Green-Green and Blue-Blue to 1.
-Set the top clone layer blend mode to screen.
-Offset the layers slightly on the X and give each layer a bit of rotation to fake some perspective. This may also require publishing scale controls to handle visible edges from the screen blend mode.


If you are actually trying to merge the left and right eyed of an anaglyph, I'd just make a left eye and right eye Motion Effect with a rig that could select the correct colors (incase someone gives you the wrong settings.

Glad you found a solution that worked! If I might add one last suggestion, I'd recommend screen over add. It will prevent you from blowing out any whites when the two images are combined (unless that's what you want ;) ).

Cheers

Hey Mark, are you sure? Every time I add a new Drop Zone to a project and check the Project layer the drop zone is already automatically added. I even checked on two systems to make sure I wasn't crazy. ;)
