I have two videos, an animation, and a greenscreened interview on a image background. I want the final export to be high enough quality that it will look clear on a large screen. The video file is going to be played off of a dvd that is going to be made through idvd. What Composition and rendering settings should i using including formats,codecs, etc?
If you're making a DVD video, then you don't have a lot of choices. The DVD specification is very strict. Use the composition settings preset and output module settings preset for MPEG-2 DVD (NTSC DV).
ok thanks. So what should all the options/settings be for for the comp and output/render?
I just told you which presets to use. Presets are collections of settings. If you don't understand this answer, then you really need to read the basic documentation.
I again recommend that you work your way through all of the basic getting-started materials.
