Thanks for the advice Dave.
I think I do have the field order nailed at the moment for after effects/premier ads when there is no actual filmed footage, I just always render everything upper field first and seem to go through the system ok.
My question now is when I next do a commercial (or any video project) that has filmed footage on my dv camera, do I create a upper field first project in premier and capture my footage this way or do I capture it in a lower field first project and drop it into an UFF project?
To many options???
As for just using progressive, this seemed to create problems with the broadcaster as it’s only a SD broadcast snd dubsat also are not yet accepting high def files, and although a great service, when asked for mpeg setting they were VERY breif!
