video is stretched sideways when DVD>xvid with GK

[_N_]

I took a DVD with a VOB,
I need to convert it into xvid so it fits onto a CD.

I believe that this error is caused by croping the picture a bit (because it had black around it, I cropped it by 2 pixels around the edge in GK)

This is what the VOB looks like:
http://onlygod.orcon.net.nz/before.jpg

http://onlygod.orcon.net.nz/before.jpg

and this is what it looks like after,
http://onlygod.orcon.net.nz/after.jpg

The thing is, in GK, when I went to save and encode, and then you do a final preview before letting it encode, it looked ok,
so, does anyone know what this error is?

I'm guessing that you've violated some cropping or resizing restriction, but that's just a wild guess. To get closer to the real problem:


:logfile: :logfile: :logfile: :logfile:

and don't forget your AviSynth script (.avs file):

oops,
I don't really understand much of the avs file,
but here it is:

LanczosResize(708,522)
AS jggimi said. Try to resize by a multiple of 16 at least.(Both aren't!) (GK is 32x16 by default, for a very good reason). I should say it should look good then :)

[jggimi]

708 is Mod 4, and 522 is Mod 2. YV12 colorspace (used by DVDs and by GKnot) requires Mod 4.

But you'll get better compression if you go no lower than Mod 16, due to the way MPEG-4 macroblock technology works, and some video cards need Mod 32 width, which is why Gknot's defaults (32/16) are recommended.

ok, thanks, I didn't know that,
