I imported my footage from P2 ( format DVCPRO 576i) into Cs3 and started editing. I setup a custom project with DV settings but with upper field first. Everything played fine until I added an effect on a clip and rendered it. The resulting render had interlacing issues when played back via DV deck to a monitor. I reversed its field dominance, rendered again, and then it looked fine. It's a hassle to go through all the clips on my timeline to reverse the field dominance. Does someone here has a solution please? Is this an issue with the way CS3 deals with .mxf files (which I think are upper field) and DV (lower field first)?
