Tweak Color

[stej4u]

First I'd like to thank doom9 for helping noobs like me with our questions.


I have this [indian] source with horrible colors I was hoping if anyone could help me with it. I only got this far: tweak(0,1.2,0,1). I'm sure there is a better way to do this, please help.

crush the blacks :). levels(x,1.,255,0,255) should do it, just start "x" at 0 and raise it until the black level is low enough.

there's a little bit more green in the black than other colours, but if you were to handle each channel individually you'd then change the overall colour balance which is not really in the spirit of the movie.

from the look of it, the green lifted black is pretty consistently though the whole film (at least the sample given), but i'd check through the whole film with histogram() just to make sure. if you can get away with one setting for all of it, then it'll save problems.

btw, i'd be more worried about the standards-conversion that seems to have taken place... you might want to consider throwing one of the deblending scripts at it.

Thanks, I got the black that I wanted. what would you prefer for deblending? my script:

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\MT.dll")
SetMTmode(mode=2,threads=2)

DGDecode_mpeg2source("Z:\Vaada MCCE\Part 2\VideoFile.d2v", cpu=2, info=3)
ColorMatrix(hints=true, interlaced=true, threads=0)
Load_Stdcall_Plugin("C:\Program Files\megui\tools\yadif\yadif.dll")
yadif(mode=1,order=1).srestore()
crop( 2, 48, -8, -46)
tweak(0,1,-10,1)
levels(2,1.,255,0,255) #for black level
addborders(0,60,0,60)
LanczosResize(720,480)
FluxSmoothST(7,7)
LimitedSharpenFaster(Smode=3, strength=40)
