I’m disappointed in it after I spent two days trying to get a layered Photoshop file to work. After saving and rendering, any subsequent edits to the motion file caused all of the layers to get mixed up (not the order, but the actual content in the layers). I searched the posts here and at Apple and the consensus seems to be that this feature is not well implemented. I concur.
Now I’m trying to create a simple text build totally in Motion (I’m using reveal from left effect). After render a glitch frame appears as each motion layer is revealed.
I had to resort to exporting the file from Motion instead of rendering in FCP. So much for the round trip concept.
But hey, it does a great job of animating stills and for creating lower third supers.
