Ok I understand. So is it safe to assume that the preferences for exporting were altered from the default so they compressed to a much smaller size when i was getting 3 gigs for a video over 1 hour a week ago? So it may also be that the QT movies that I exported a week ago may be lower quailty because they are in fact compressed more than usual. But your reply makes perfect sense, I’m just wondering about those other videos that are over 1 hour but only like 3 gigs in size.
