Thanks for the explanation. I think I understood what you're saying but I have another question about "pulldown"....what is that? I know there are diagrams explaining it about the fields and I understand the 2:3 and 2:3:3:2 but you mentioned "removal?" Why or how should it be removed? I think Vegas can edit in 24P. I need the final product to be on DVD and viewed on a progressive scan DVD player.
