Hi
Ich hab andauernd Blockartefakte bei meinen HD2DVD
und deshalb wollte ich einen Deblock filter benutzte.
(Brother-John hat mir den Deblock_QED vorgeschlagen)
doch leider weiß ich überhaupt nicht was ich mit dem Skript machen soll damit er die Blocks von meinem film entfernt.
Das ist mein aktuelles skript um von meinem *.h264 film eine m2v zubekommen:
avcsource("C:\....dga")
assumefps(25)
lanczos4resize(720,576)
und das hier ist das skript von dem DeBlock_QED:
Code
function Deblock_QED ( clip clp, int "quant1", int "quant2",
\ int "aOff1", int "bOff1", int "aOff2", int "bOff2", int "uv" )
{
quant1 = default( quant1, 24 )
quant2 = default( quant2, 22 )
aOff1 = default( aOff1, 2 )
bOff1 = default( bOff1, 4 )
aOff2 = default( aOff2, 4 )
bOff2 = default( bOff2, 8 )
uv = default( uv, 1 ) # uv=3 -> use proposed method for chroma deblocking
# uv=2 -> no chroma deblocking at all (fastest method)
# uv=1|-1 -> directly use chroma debl. from the normal|strong deblock()
ox = clp.width()
oy = clp.height()
xmod = 16-(ox%16)
ymod = 16-(oy%16)
clp = (xmod==16) ? clp : clp.pointresize(ox+xmod,oy,0,0,ox+xmod+0.01,oy)
clp = (ymod==16) ? clp : clp.pointresize(clp.width(),oy+ymod,0,0,clp.width(),oy+ymod-0.01)
# With avisynth scripting, there is no information available about the position of the currently
# processed pixel ... there simply is no such thing like an "actual" processed pixel.
# So first I've to build up a grid covering the transitions between all 8x8 blocks,
# and make some LUTmania with it later. Yes, this is cumbersome.
block = blankclip(clp,width=6*4,height=6*4,color=$000000).addborders(4,4,4,4,color=$FFFFFF)
block = stackhorizontal( block,block,block,block)
block = stackvertical( block,block,block,block) .pointresize(32,32) .mt_binarize(upper=false)
block = stackhorizontal( block,block,block,block,block,block,block,block)
block = stackvertical( block,block,block,block,block,block)
block = stackhorizontal( block,block,block)
block = stackvertical( block,block,block)
block = (block.width < ox) ? stackhorizontal( block,block,block) : block
block = (block.height < oy) ? stackvertical( block,block ) : block
block = block .crop(0,0,ox,oy)
block = (uv!=3) ? block
\ : YtoUV(block.crop(0,0,ox/2,oy/2),block.crop(0,0,ox/2,oy/2),block)
block = block.trim(1,1) .loop(framecount(clp))
block2 = mt_lutxy(block.mt_expand(U=3,V=3),block,"x y -","x y -","x y -",U=3,V=3)
# create normal deblocking (for block borders) and strong deblocking (for block interiour)
normal = clp.deblock(quant=quant1,aOffset=aOff1,bOffset=bOff1)
strong = clp.deblock(quant=quant2,aOffset=aOff2,bOffset=bOff2)
# build difference maps of both
normalD = mt_makediff(clp,normal,U=uv,V=uv)
strongD = mt_makediff(clp,strong,U=uv,V=uv)
# separate border values of the difference maps, and set the interiours to '128'
strongD2 = mt_lutxy(StrongD,block,"y 255 == x 128 ?","y 255 == x 128 ?","y 255 == x 128 ?",U=uv,V=uv)
normalD2 = mt_lutxy(normalD,block,"y 255 == x 128 ?","y 255 == x 128 ?","y 255 == x 128 ?",U=uv,V=uv)
# interpolate the border values over the whole block: DCTFilter can do it. (Kiss to Tom Barry!)
# (Note: this is not fully accurate, but a reasonable approximation.)
strongD3 = strongD2.mt_lut("x 128 - 1.0 * 4 * 128 +","x 128 - 1.0 * 4 * 128 +","x 128 - 1.0 * 4 * 128 +",U=uv,V=uv).dctfilter(1.0,1.0,0.0,0.0,0.0,0.0,0.0,0.0)# .yv12lut("x 128 - 2 / 128 +")
# apply compensation from "normal" deblocking to the borders of the full-block-compensations calculated
# from "strong" deblocking ...
strongD4 = mt_lutxy(strongD3,normalD2,"y 128 == x 128 - 4 / 128 + y ?","y 128 == x 128 - 4 / 128 + y ?","y 128 == x 128 - 4 / 128 + y ?",U=uv,V=uv)
#strongD4=maskedmerge(strongD4,strongD4.removegrain(19),block2,U=3,V=3)
# ... and apply it.
deblocked= mt_makediff(clp,strongD4,U=uv,V=uv)
# simple decisions how to treat chroma
deblocked = (uv < 0) ? deblocked.mergechroma(strong) : uv < 2 ? deblocked.mergechroma(normal) : deblocked
deblocked
xmod==16 ? last : last.crop(0,0,-xmod,-0)Hoffentlich weiß einer wie ich das in meinem skript einbinde
damit endlich diese blockartefakte verschwinden.
-danke
