I have been reading alot on encoding and authoring a VIDEO_TS for burning a dvd. I don't have any problem burning a dvd, but have questions on resolution settings and quality/time settings. I want to fit about 5 hours of mpeg1 video on a dvdr. I know that you need to encode audio into 48khz, and I am probably going to check out some TMPGENc templates off of www.kvcd.com. My tools I use are, TMPGENc, Ulead DVD Movie Studio. My question is... The mpeg1 video I have is I believe 352x240. I have made a dvd with about 400 minutes at 352x240, and successfully created the dvd, but quality was low and there was quite a bit of artifacting. Should I encode the video to 352x480? Is there a quality loss when converting to a higher resolution? If I use a template and make sure audio is 48khz, and resolution is 352x480, should the quality be alot better? Any help would be greatly apprieciated!
