          MPEG is an inappropriate format for editing and compositing. Export from Vegas in a lossless format for the best results: Quicktime Animation (100%) or Uncompressed AVI are suitable options.

            But with which settings? Elementary stream? Program stream? Transport Stream? What is the GOP interval? Data rates? There's so many sub-formats and derivatives of MPEG, it's nearly impossible to cater for them all, so unless you stick to the specs, there's no guarantees. And then of course Andrew is right - since you have access to the source files in your editing program, why not simply use a more suitable format? Uncompressed is of course ideal, but if you are tight on disk space (which, considering that harddrives are rat cheap, is still no good excuse), you may also use CoDecs such as Foto-JPEG with about 95% compression.

              I use Vegas a lot, and it sort of sounds like the poster may be somewhat
              new. Likely he is exporting using the standard Mainconcept MPG2 and
              probably a default present for an NTSC DVD compliant video. As was
              mentioned in the post before yours however, MPG in any flavor is really
              not appropriate. The QT Animation codec with millions of colors plus is
              probably the best choice, or, if the really easy button is desired, just
              the "Render to New Track" function will put a AVI DV format rendered
              copy onto a new track, and a file of that name will be in the project
              folder as well. Heck, no point rendering anything out for use in AE that
              does not keep the alpha channel.
