I've been trying to make the jump from a layer based compositor, After Effects, to a node based compositor, BMD Fusion.  So far it hasn't been easy, I've been running up against a lot of basic issues like "How do I move something?"

One issue that really drove me crazy was Fusion's built in tracker.  It's confusing, and it's crappy.  I just don't like.  I was happy to find out that Mocha Pro integrates with Fusion very well, so I don't have to use their crappy tracking system.  I can use the system I know and love.
