After I render and few seconds to test the hairingbone is very bad. I have set the video as directed by tech support. Render out video and then the 5.1 audio. The pix is set to ntsc widescreen,,,, 1.21. I am working with a new SONY BlueRay videocamera. When I play back from PBM the video is super fine,,, GREAT! Love this camera..... After Vegas it is very bad. It is set to the sorce,,, 1920x1080 and I am doing a DVD of a wedding.. Did some testing: interpolation,,,, blend,, and none... See no change between interpolations and blend.. None give me a beautiful video.. What I need is DVD for TV for the bride and groom...Will this hairingbone show when set to blend show on the fnished DVD for TV? Thank You
