Thanks. I've updated the first post to mirror your function. Avspmod adds some text formatting which shouldn't affect functionality but obviously if you can't run the function then it should be laid out so that it will work for everyone. If that's even possible with a program like avisynth lol. I'm using avisynth 2.58 btw.
It's good that you had the knowledge to make it work :)
EDIT: I also named it LDdenoise at first but then I thought dnoise sounds the same as denoise and there's one less character to type. I'm a lazy bastard lol.
