1080p is not a measure of quality, but simply a measure of the frame size. Data rate is the main arbiter of quality. So, you may be losing ‘quality’ on your initial transcode to MPEG, and then another transcode when Encore transcodes again to MPEG-2 to burn onto the DVD. It would be helpful to post some info such as your transcode settings in both Adobe Media Encoder as well as those in Encore. Also, what’s the runtime of your full program? If it’s long, Encore will adjust the data rate for your encode to place the most amount on a single DVD with the highest quality(data rate). That data rate will be a lot higher for a 30 minute program as compared to a 90 minute one.
Why do the initial MPEG transcode? CS5 should be able to handle NXCAM footage from what I read.
