i have the new sony hc3 hd cam. been recording footage in the 1080i aspect and it looks great. i have the new creative prodution studio (pp2, ae7, etc...). i capture the footage off the tape in hd as a mpeg with pp2. 1 hour hd seems to be about 10gigs. now i want to edit the footage off of several tapes and makes dvd's to watch the footage on. I have a HD-DVD player but dont have a burner yet. plus my customers will be watching this on regular DVD anyway. so my question is after capturing and i have these 10gig mpegs to work with, what format should i convert these movies to to edit and burn to dvd's? should i edit them in hd format then convert and burn the final project or should i just convert the files to something first then edit and play with the smaller files?
