Thanks for the info. I figured it out for now. Basically, cut in a 1080i workflow then bring it into a 720p workflow when I’m completely finished and render accordingly. When you bring 1080i footage into a 720p workflow it scales the picture down by 75%. This means if I bump it up to 100% I’m getting a close-up in post. That was the original idea but I didn’t anticipate the rendering.
As for 720p 24pn footage into DVD I’ve been shooting quite a bit in that format and making DVDs without any problems. I use compressor to handle the compression and I don’t take any extraordinary measure because of the 24pn. Just make sure you’re shooting in 24pn not 24pa which you’ll need to do a pulldown removal in order to edit in a 29.97 sequence.
