I have a stock close of about 10 seconds in SD that I tag our productions with. It is in an uncompressed AVI format. All I have to do is drag it to the timeline at the end of a show and that's it. Now, I have re-created it in HD in 1920x1080 with 5.1 surround. What would be the best format to render it in so I can do the same with an HDV production?
