Trying to remember here:
-Put 1080i on timeline
-Project properties 720 60p (so set your project to your desired final output).
-I think I right clicked the timeline event and selected "smart resample" on the switches options
Test each frame by going one-by-one on the timeline. I verified that each frame was a unique picture. I believe it essentially converted each field into a frame.
Since no DVD format would be compatible with it, I assume you will be outputting for Web. It worked, but not sure of the value I obtained?
