Actually, NTSC frame rate is 29.97 fps, but you can render in Carrara or RDS at 30 FPS and your editing system will convert the frame rate (if you're using Premiere, FCP, Media 100, AVID or any of the bigger NLE's). If you're mixing your footage with DV acquired footage -- say Mini-DV, DV-CAM, Digital-8 or the like -- you will likely want to render using non-square pixels (I seem to remember that Carrara has that option, though I don't have it open in front of me at the moment) at a resolution of 720x 480 or 720 x 486. Again, if you render at 640 x 480 (which is American TV's standard aspect ratio in square pixels) and drop the movie onto a Premiere timeline, Premiere will automatically convert it to whatever resolution you're outputting. I use Carrara (and used RDS for years before) to produce broadcast graphics. I always render at 640 x 480 at 30 fps and let my NLE convert it as necessary. Hope that's helpful. - Dex
