If someone were going to film an all greenscreen film, which hopefully would be screened at film festivals (on big screens), using CGI backdrops, at what resolution should the images be rendered?

Generally at whatever your output resolution is. So I am guessing miniDV, but HD or Film, or some other high end format would definatley be prefferable. Especially when working with greenscreen footage

Maybe I wasn't too clear. What I want to know is what the pixel size of the CGI backdrop should be in order to look good. If the image is going to be shown on a big screen, I'm assuming the image would be pixellated if not rendered large enough. Just wondering if anyone has done this and seen the results on the big screen.

Well im guessing your video output will be around 720x480. To have the backgrounds composite better, you should keep the same resolution or higher for your backgrounds than your fottage

As long as the resolution of the background is above or exactly the pixel size of your movie, there shouldn't be any more pixelation than what you would experience using the footage shot with your camera. Since your NLE will scale down the imported backdrop to your project settings it wouldn't really matter that much what the pixel size of the backdrop is. Although make make sure it's at least the size of your project.

To 'dumb-it-down' for you after you render the movie you can right click on the file and check the pixel size in the properties what ever the Heigth and Width is thats the size you want to render your animation/CGI.
