640x352? 720x400? 768x432? 1280x720? 1920x1080? There is no universal 'widescreen' resolution, since 'widescreen' (or 16:9) only refer to the basic shape of the image - i.e., that it's much more rectangular than square. So the dimensions can change based on what you want either your horizontal or vertical resolution to be.Senvae wrote:Thanks, that's what I was planning to do, but I thought the widescreen res was something like 600x300 (roughly, don't remember the exact numbers). I will try that 848 resolution then.
Generally, a 'Letterboxed' DVD is 4:3 (Fullscreen), but the video has been proportionally resized to fit in a 4:3 frame and then black mattes are added to the top and bottom; usually the actual picture is 640x368, 640x360, 640x352. 'Anamorphic widescreen' (Enhanced for 16x9, etc.) DVDs, like AMG!, are stored in the same 720x480 dimensions, but they've been horizontally squished because it makes compression more efficient, and the file has a flag telling the player that it's supposed to be 16:9. On playback, the DVD player basically resizes it to 848x480. Even 4:3 content has those flags, since 720x480 is actually 3:2 ratio, and to display the content correctly it needs to contract the image back to 640x480.
The 'mod16' thing I mentioned before is simply an easier way of saying the dimensions are multiples of 16, since adhering to mod16 resolutions helps with the compressibility of video in formats like MPEG-1/2, MPEG-4 ASP (Xvid), H.264, etc.
