What I do is create my graphics in 720×486 and then use those in the 720×480 offline. When you put the bigger graphic in the timeline. FCP should automatically put a -1 in the vertical position value in the motion tab. The pain is when you of the online you will have to manually go through and adjust each one up back to a 0,0 position. You can do this easily by selecting all of the graphic clips in the timeline and control clicking one clip and selecting remove attributes and then select basic motion, but BE WARNED if you have moved or keyframed anything this will blow those moves/keyframes away. Then you are stuck doing those clips one by one. This should only effect anything with video in it. Stills shouldn’t make a difference as they are not interlaced. When you put a 720×486 video graphic in a 720×480 timeline, you are essentially reversing the field order until you shove it down a pixel, that’s why it won’t look correct. If you can’t recreate your graphics for the online, then simply do the same thing. Shove your 720×480 video graphic down a pixel and all should be well in 720×486 land. You will of course need to render everything. I have always wished and wanted capture card companies would devise their own offline/online codecs so that we could work easier without going through this rigamarole, but I digress. I am just keeping hope alive and thinking that this will be addressed in some future version of FCP.
Make sense?
