Gknot vs flask

[yjeep93]

I have a 16:9 NTSC anamorphic DVD 720x480

I want to have an output resolution of 720x480. Gknot won't let me do this. Because of that damn slider bar, the highest I can go is 720x416 with an aspect error of 2.7%. Also the H-Zoom is only 87% (I want the damn thing to say 100%)

I have a friend with Flask, and he can encode at 720x480, no problem; and it's still in a 16:9 aspect ratio.

I rip all my movies to at 1.4 gig, so 99% of the time my bits/(pixel*frame) is never a problem. How can I get Gknot to encode for me at 720X480? I use gknot 0.27 release.

thanks,
jonathan

If you want to keep it just as it is ... just edit it when you save the avs. Comment out (aka. put '#' in front of) the crop and resize.

Kind of...it gives me an output of 720x480, but my AR is not correct. The 1:1 stretches my picture vertically.

When I save my avs it doesn't have the crop and resize stats in the file name.

Why can flask keep it at 16:9 (1:1.185) with 720x480, while Gknot doesn't? Am I missing something here?

The settings are not stored in the filename. You have to either push edit button before you save (or save & encode) and it will show you the text script that you made. Or you could open the avs in notepad after you save it.

I should warn you, that commenting out those lines will give you the video as it is stored on the hard drive. If there are resize flags set inside the video they will be ignored and the video will not look right.

Also, (just to make sure) make sure that in the video window part of Gordian Knot make sure to check View/Resize to see what it will be like after resizing.

If you want to retain the original unresized resolution of a commercial DVD's video stream, be aware that: All NTSC DVDs are 720x480.

With square pixels, that is an aspect ratio of 1.5:1.

Display of the finished AVI will need to be in a player that can resize to 4:3 or 16:9 -- the Display Aspect Ratio.

Players that can do this include BSPlayer and Zoomplayer.

Without cropping, you will be encoding letterboxing along with the useful content for video streams that are not 1.33:1 (4:3) or 1.85:1 (16:9), such as Cinemascope (2.35:1).If this is at all confusing, see Doom9's Aspect Ratios Explained (http://www.doom9.org/aspectratios.htm).

I thought NTSC also came in 640x480?
