AviSynth Fix analog capture color problems
#1
A very simple but effective way to eliminate cross colors, rainbows, and other "nice gifts" we can find in our analog captures, in particular from composite formast, like the darling VHS and our beloved laserdisc.

It reduce chroma at 1/4th of the original; don't worry, because even the best Super-NTSC encoded laserdisc will barely suffer using this function; just try and let me know! Thanks to antcuufaalb!!!


Code:
function lowchromanoise (clip clip) {
clip
SeparateFields
Spline16Resize(clip.width/4,clip.height/2)
Spline16Resize(clip.width,clip.height/2)
Weave
MergeLuma(clip)
}
