Hey Adam,
If you happen to check back into this thread, I have a question about the 1 pixel y-axis adjustment:
Using the method you suggested, I first put my 720×480 sequence into a 720×486 timeline, but then I need to bump my media up one y-axis pixel to account for the new interlacing pattern. This would mean I’d have to go into each clip and change the motion settings one by one. To avoid that, could I export an FCP movie out of the 720×486 sequence, reimport it, and then bump the whole movie up by 1 y-axis pixel?
Thanks very much,
Ella
