Using Sony Vegas Pro 9 to create mpg 2 for DVD, Sony DVD Architect Pro to author the DVD. DVD Architect always tells me it's going to recompress the file. Is it possible to do this so DVD Architect doesn't recompress the audio or video?
The post-VPro 10 webinar notes article is not on the SCS site any more, but it included the following note. Recompression only takes place when you’ve imported media that doesn’t properly match the requirements of burning the disc. If you import MPEG-2 video for DVDs and MPEG-2 or AVC (H.264) video for Blu-ray discs as well as AC3 audio (or PCM) for both types, the only compression DVD Architect will have to do is for the menus or any multiple video angles.
