I am using Sony Vegas Studio 10 Platinum to edit video taken from a Sony Handycam(avi video I think) in 480p(max).When I edit the video in Vegas and the save it as either an AVI or WMV file, the quality looks a bit worse; however, more importantly their is a fairly unacceptable amount of letterboxing on all sides of the video(kind of like watching a 480p content on a HD tv/channel). I tried everything to remove it, but that is a no go there. The setting shows that it is in 480p. Any ideas? Thanks.
