Problem with cropping numbers...

[OBcecado]

Hi, can someone please explain-me what can I do so I don't get this error message ?
Avisynth open failure :
Crop YV12 images can only be cropped by even numbers (top).
I'm using newest avisynth version with the plugin pack...
The script is the following:
mpeg2source ("c:\stuff\stuff.d2v")
crop(0,3,720,569)
BicubicResize(576,320,0,0.75)
Convolution3d (preset="movieHQ")
dup(copy=true, maxcopies=20, blend=true)

Umm, you can't use odd numbers for your crop.
crop(0,3,720,569)

Because you are cropping 3 pixels from the right and 3 is no even number ;-)
Edit: I have to learn how to type faster and error free :P

Change that to an even number or use croping directly in BicubicRezise (please read the docu or search the forum, i'm not sure how to do this exactly)

CU,

Thanks, gotta check numbers better next time, I got those numbers from gknot, which were wrong, but if i choose a higher resolution, then a lower it gives me numbers, that are multiples of 8.

Best regards.

Well, 569 isn't even multiple of 2, so multiple of 8 will still be better ;)

Short Answer :-

mpeg2source ("c:\stuff\stuff.d2v")
BicubicResize(576,320,0,0.75, 0.0, 3.0, 720.0, 569.0)
Convolution3d (preset="movieHQ")
dup(copy=true, maxcopies=20, blend=true)

Seems like we finally found a use for the crop settings in resize. Since UV is already being interpolated (or filtered if you like) it seems safe to use - even quality-wise.
