If you are going to put it on a DVD and use a video projector then 720x480 for 4x3 or 720 x405 for 16x9. Even though video projectors have a higher resolution 800x600 or better, if the source is not a computer but a DVD player then there is no point to render any higher. Full frame are nice, but it will eat you hard drive of space. Any encoder that is 100 percent will be fine. Most have adjustments to change it from 100. Make sure the settings are at 100%. Dale
