Edit: Updated - See Post # 157

I've written a script that I think is pretty interesting. I should clean this up, but I'm away from my normal computer and I'm very used to using AVSPMod.

Requirements are:
defreq
Masktools2

Using the latest script, will update this post later.


Edit: Updated to the latest version. A note: this is for colorization, don't expect miracles! Sorry if I was misleading in the beginning of this thread, it wasn't on purpose. I was confused as well!

Edit: Sorry folks, as davidhorman pointed out this needs to have a call to greyscale! Code updated.
