Output resolution

[Nasty64]

I've looked throughout the forum and haven't been able to find anything on this:

I have DVDs that are 720x480 and I'd like to specify an output resolution of 720x480. Is there a way to do that?

Thanks...

1) Are you using Gordian Knot or AutoGK?

2) Are you aware that many .vobs are anamorphic widescreen, and if you try to set 720 x 480 the output won't look right?

DVDs -- commercially produced ones, anyway -- have a fixed resolution: 720x480 if NTSC, 720x576 if PAL. These pixels are not square, unlike the pixels of a PC monitor. (And if .avi files are played back on an .avi-capable standalone player, it expects square pixels as well.)

DVDs will be flagged with a Display Aspect Ratio (DAR) of 4:3 or 16:9. GK/AutoGK will recognize this and resize to square pixels for you.

A "widescreen" movie should have a DAR of 16:9, but there is no reason it must. There are plenty of "widescreen" DVDs out there with DARs set to 4:3. It just means there's less pixels for the movie, and more for letterboxing.

EDIT: Yes, you can encode DVDs to .avi with no resizing ... but, you must use a player that resizes on playback.
