Hi, I used to use that program pretty frequently. I usually use these settings: Video Settings - Disable re-sample, Studio to computer RGB. Rendering - Mainconcept AVC MP4, 20 Mbps (for 1080p, 15 for 720p), Dual Pass, 30/60 FPS. This method is pretty lengthy but usually has good results. For quicker rendering times I would use Sony AVC, CABAC, 20 Mbps (for 1080p, 15 for 720p), 30 FPS. With these settings you can allocate your GPU to do the rendering, but I think thats only Vegas Pro 10.
