Question about using input resolution of source file with gknot

[Sgt_Strider]

I need someone here to double check on my method of encoding with the resolution of my source files. Anyway I rip a NTSC DVD (Black Hawk Down) and its resolution is 720x480. I want to reencode the movie at the resolution of the DVD or the source's resolution. Since there is no option that I can tick like in WM9 Encoder(Same as video input's resolution), I use tick the following in Gknot's resolution tab: Input resolution: NTSC, Input Pixel Aspect Ratio: 1:1, Crop: Disable, W-Mod: 16 and H-Mod: 32. By choosing those settings, I can safetly move the slider to the right until I get to choose the resolution 720x480. The thing that troubles me is that the output .avs file from gknot seem to enable cropping and resizing.

#
# CROPPING
crop(0,0,720,480)
#
# RESIZING
BicubicResize(720,480,0,0.5)

My basic question is am I doing this properly and what should I do about the avs script? Disable resizing/cropping? Or both? Also will the final video look just like the original DVD, meaning same resolution with nothing look squish/squash. Thx

If you're goal is to leave the resolution exactly as the input (why?) then you should simply comment out those lines in your script. Add a # before the crop and bicubicresize commands and they won't be used.

All the settings under the resolution tab are useless in this case and you needn't bother with it.

This is not the recommended way to make a DVD-rip, but I guess you've got a special reason.

I want to preserve as much detail as possible.

Hi-

I want to preserve as much detail as possible.

OK, I can understand that. But what are you doing about the black bars? Are you leaving them in? Many, if not most, DVDs will have some on top and bottom, and sometimes to the left and right also. And then what are you doing about the incorrect AR? Will your player be doing the resizing? And then because of the large number of pixels you're encoding, you're doing many of these for 3 CDs so that they'll look halfway decent?

But assuming you're aware of these issues, N_F gave you the answer. You have to edit the .avs to either comment out or erase the Crop and Resize lines.

I have done this in the past; usually for short featurettes, not for entire films. The primary reason was to preserve as much as possible, and my encoding method was single pass 100% quality; so Gknot was only used as an .avs creation tool, not a bitrate calculator. (Though you can now use Gknot 0.28 for this purpose).

As Manono, said, you will need an AVI player capable of producing 1.85:1/16:9 DAR or 1.33:1/4:3 from your 1.5:1 video source Possibilities include BSPlayer and Zoomplayer, two popular choices.

imo it's all about compressing as much as possible usually 700-800 for a movie, if you don't want to loose quality maybe better not to recompress at all...
