mg262's CompareVersions
Code:
Function CompareVersions(clip A, clip B, bool "copy") {
# (c) mg262, http://forum.doom9.org/showthread.php?p=679687#post679687
A=A.ConvertToYUY2()
B=B.ConvertToYUY2()
copy = default(copy, false)
halfwidth = A.Width()/2
left = A.crop(0, 0, halfwidth,0)
right = copy ? B.crop(0, 0, halfwidth,0) : B.crop(halfwidth, 0, 0, 0)
return stackHorizontal(left, right)
}
EDIT: By the way, the vectorscope images on ColourLike thread, I think the upper two images
are the source images (eg dvd and vhs) and the lower two are the two images produced via
ColourLike when converting eg dvd->vhs colors and vhs->dvd colors.
EDIT: There is a native Avisynth version of VectorScope on WarpEnterprises, modded by Wilbert.
EDIT: Updated ColourLike helpfile
EDIT: ColorYUV2() now available here, with Graffers:
