Hi, I recently bought sony vegas movie studio platinum edition. I made a slideshow for a dvd I'm making in vegas movie studio and then rendered it as mpeg 2, DVD architect NTSC video stream. I then put it as the background for my DVD menu and burned the DVD as I watched it I was quite disappointed at the quality I am not sure if there is a way for better quality or not but it was pretty bad for some of the slides I had the moving across the screen using Track Motion and when I looked at them on the TV they would flicker as they moved and the edges were out of line and the overall quality was pretty bad!
I already set the video options for the highest amount of pixels and 29FPS and set the quality to BEST Whats wrong? I need software with quality I hope Vegas will be able to do that.

One problem you have is that when you use an MPEG file as a background it has to be recompressed to MPEG again. Recompressing MPEG to MPEG always suffers a quality hit. You should render the slide show as DV or even as uncompressed AVI if it's short enough. That way when DVDA prepares the menu it will be the first MPEG compression.

There is also an option to "reduce interlace flicker" in the property settings in Vegas. You'll want to use this whenever you move a still image around.

I had this problem a long time ago and everyone said I was nuts. It nice that Cheinworks could explain it and I was right.

What I do now is to render all files with Cineform. Since everything I was doing was 4:3, I set up Cinform to render a custom 960 x 720p size which saved alot of space and still gave you a HD image. The nice thing is that anything you render with this method will look absolutely beautiful on your computer. The experts will tell you I'm full of bull, but I swear the movie conversions on DVDA will look much better also.

I believe the Cineform files process faster than the DV files, and DVDA runs them just fine with only a small increase in processing time when you start to burn. The files are a little bigger but it is the only file you ever need from start to finish.

One other Tip. If you're making a shorter movie using DVDA and you go to prepare, the automatic optimize button will not set the MBPS rate over 8.00 no matter how much spare room there is on the disc - push it on up to 9.80.

Audio: 48,000 Hz, 16 Bit, Stereo, PCM Uncompressed.
Video: 29.97 fps, 960x720, Progressive.
Pixel Aspect Ratio: 1.000, using CineForm HDV codec. OpenDML compatible.
