Request for help to convert some Avisynth functions
I'm trying to make the switch from Avisynth 2.6 to Vapoursynth as Avisynth has become very unstable ever since I got an i7. I'm currently trying to get the hang of the syntax and convert the stuff I always use to process videos.
I'm having some difficulties in converting the predenoiser helper functions that I use. Could someone please take a look at them and show some magic? There could be some native alternatives in Vapoursynth that I don't know of so feel free to customize if needed Code:
function Prefilter (clip c, int "th", bool "chromamotion") { chromamotion = default(chromamotion, true) output = Flux5framesT(c,th=th,chromamotion=chromamotion) return output } function Flux5framesT(clip c, int "th", int "thC", bool "chromamotion") { chromamotion = default(chromamotion, true) th = default(th, 2) thC = default(thC, chromamotion ? th : 0) med = chromamotion ? ytouv(c.utoy8().median5t(), c.vtoy8().median5t(), c.median5t()) : c.median5t().mergechroma(c) avg = c.temporalsoften(2, th, thC, 24, 2) output = interleave(c, med, avg).clense(grey=!chromamotion).selectevery(3,1) return output } function median5t(clip src) { function min(clip a, clip b) {return mt_logic(a, b, mode="min")} function max(clip a, clip b) {return mt_logic(a, b, mode="max")} src last + trim(framecount()-1,-1).loop(5) bcmin = min(SelectEvery(2, -1), SelectEvery(2, 0)) bcmax = max(SelectEvery(2, -1), SelectEvery(2, 0)) demin = bcmin.SelectEvery(1, 1) demax = bcmax.SelectEvery(1, 1) x = max(bcmin, demin) y = min(bcmax, demax) a = SelectEvery(2, -2) f = SelectEvery(2, 3) Interleave(a, x, y, f).Clense(grey=true).SelectEvery(4, 1, 2) trim(0,length=src.framecount()) }
