Hey, just a quick OT thank you.
I was working on another project today and the source had some unpleasant aliasing. I remembered a line in this script about it:
########## anti-alias
NNEDI2(dh=true, field=0)
NNEDI2(dh=false,field=1)
I've never seen that done before, I'm not sure HOW it works, but it does a beautiful job. Thanks.
