I too had output problems with Motion on both a Mac Pro and a new MacBook Pro.
In the case of the MacBook Pro, I had upgraded to Lion over an existing Snow Leopard installation. On the Mac Pro, I was still running Snow Leopard.
Since my laptop was new I decided to experiment and I zero’ed the drive and installed Lion. Then used Software Update to insure Lion was up to date. Then I installed FCPX and Motion 5. Nothing else. Now, Motion output is perfect. On my Mac Pro, still running Snow Leopard, Motion 5 still has faulty output.
Draw from that what you may. It appears that some other app is interfering but I can’t be certain. Just telling you my story on the way it happened on how I got good output.
I left a message similar to this in another thread and asked others with the problem to share with me what other apps are running to see if we could identify the culprit but have had no takers. I had Adobe CS 5.5 Master Collection on both computers and haven’t yet put it back on my laptop with its clean Lion installation, but that’s my next step, although, I think it’s unlikely that CS 5.5 Master Collection is the conflict.
