Standard North American NTSC DVD-video is 720x480 mpeg2 at 29.97 fps. You will need a DVD authoring software that allows you to override 480p if you want to encode as 720p or 1080p. But that will mean that most standard DVD players will not be able to play the video. Some newer players (and computers or course) can handle higher resolution mpeg2, or use a scaling algorthm to upconvert 480p to 720p or 1080p (mine does a fair job scaling for my 40in 1080p LCD). Otherwise, you need to go go Blue-Ray for HD. As for the text, you will have to choose a font and font size optimized for 480p NTSC display with consideration of what TV or screen size will be used (CRT, LCD, projection etc etc). Keep text simple, don't crowd too much text, use sans serif, for example. A discussion of TV display fonts is a large topic with many opinions. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
