Hi Chris,
We are trying to do almost the same thing at the moment. We have some Varicam footage 720p/60FPS which I want to edit on Premiere Pro 2.0. We have not tried to capture it directly into Premiere rather we captured the footage into FCP and then exported the file as a quicktime in the H.264 codec. This file format opens fine in premiere however I have a blackmagic (SD) card and so far have been editing it as a Motion JPEG 720p Varicam project. I am able to output from Premiere to a 1280 x 720 AVI file that will play on the computer via Windows media player and it looks great. I also have the Mainconcept Pro HD plug in for PP2 but have not had much luck with it on this particular task.
Do you know anyone with a Mac and FCP? Please let me know if you do have success as I would like to capture varicam footage directly into Premiere as well.
Good luck
George
