I've been trying to figure out if it is posssible to mask a filter applied to a clip in Motion 2 or in FCP, so as it only effects a selected portion of the frame. For instance, say I just want to darken or blur a specific area. Thanks for any advice.

If you're going to be applying any complicated moves on the layer, you might want to nest the original & masked layers together, then apply the motions to the nested layer. That way, when you make changes to the move, you only have to apply them to one object.
