  1. Hi there, i have one footage, is source was ripped from vhs i don't know, but i got it on dvd (.vob). I'm trying to restore in AvsPmod code and wondering what else could be add? I wanna say that time is no matter, the main aspect = most better restoration quality/color, so if i can run it for 1 week on my cpu - that's no problem.
    My avspmod code:
    PHP Code:
    MPEG2Source("Cutted.mpg.d2v")
    AssumeBFF()
    Tweak(sat=1.2,coring=false,dither=true)
    ColorYUV(off_y=-4)
    QTGMC(preset="Placebo"SourceMatch=3Lossless=2MatchEnhance=0.75EdiThreads=1NoiseProcess=0ChromaNoise=false )
    PreFetch(7
    Some screenshots of original file:

    That video is fubar, not even worth correcting.

    - the interlace was ruined, the video is just blurring mess now. it needs to be properly recaptured.
    - darks are crushed.
    - timing wiggles (no line TBC used)

    ^ None of that can be fixed.

    - chroma noise exists, somewhat fixable in VirtualDub and/or Avisynth
    - color actually isn't terrible, but buried behind a bad signal

    Sadly this is the only version that exist. I'm working with Avisynth, found this plugin for Chroma noise http://avisynth.nl/index.php/Cnr2 is it good or there are something new and better?
    Also tried it

    MPEG2Source("Cutted.mpg.d2v")
    AssumeBFF()
    Tweak(sat=1.2,coring=false,dither=true)
    ColorYUV(off_y=-4)
    QTGMC(preset="Placebo", SourceMatch=3, Lossless=2, MatchEnhance=0.75, EdiThreads=1, NoiseProcess=0, ChromaNoise=false )
    Cnr2(mode="oxx", scdthr=110.9, lm=192, un=111, um=255, vn=166, vm=255, log=false, sceneChroma=true)
    PreFetch(7)

    Bu i don't see any difference, am i calling variable Cnr2 wrong in the code?

    Perhaps try Temporal soften
    https://avisynth.org.ru/docs/english/corefilters/soften.htm

    For example:
    Code:
    TemporalSoften(3, 4, 1, scenechange=15, mode=2)

  5. One way to see small differences is to interleave before and after versions.

    Code:
    Interleave(last, Cnr2(mode="oxx", scdthr=110.9, lm=192, un=111, um=255, vn=166, vm=255, log=false, sceneChroma=true))
    Another useful tool is to view the U and V channels directly (as greyscale):

    Code:
    Interleave(last, Cnr2(mode="oxx", scdthr=110.9, lm=192, un=111, um=255, vn=166, vm=255, log=false, sceneChroma=true))
    StackHorizontal(last, StackVertical(UtoY(), VtoY()))
    Open the script in an editor (like VirtualDub) and you can use the arrow keys to swap back and forth between the the two.

  6. My settings for CNR2:

    Cnr2("oxx",8,16,191,100,255,32,255,false)

  7. I might do something like this:

    Code:
    Mpeg2Source("cutted.d2v", CPU2="xxxxxx", Info=3) 
    ColorYUV(levels="TV->PC").ColorYUV(gamma_y=30).ColorYUV(levels="PC->TV")
    TFM(d2v="D:\Downloads\cutted.d2v") 
    TDecimate() 
    vInverse()
    
    BilinearResize(width/2, height/2)
    luma = MCTemporalDenoise(settings="medium").aWarpSharp2(depth=5).Sharpen(0.3)
    chroma = MCtemporalDenoise(settings="very high").aWarpSharp2(depth=15).Sharpen(0.5)
    MergeChroma(luma, chroma)
    nnedi3_rpow2(2, cshift="Spline36Resize")
    aWarpSharp2(depth=5)
    This leaves some out of gamut colors. Reducing the saturation a bit should help with that.

  8. Here's a radical idea, go to You Tube and search for Tupac videos, you'll probably find a much higher quality version in a few minutes.

    I highly doubt that.

    This music video is called "Toss it up beach version" and sadly there is no better quality because this is unreleased. Also there is no music vids in good qualiy, because yt compressing video and ppl don't know what is it interlaced video

    This version of video was shoot on 35mm film, ofcourse there is somwhere a film reel in Interscope records archive of this video which can be digitized to 4k hdr, but I mean this is the only version (vob from DVD) which is exist for the fans 😭There is also somewhere vhs copies which I think has better quality, but to get it, this is the "mission impossible"

    First thing that pops up when you type in "Toss it up beach version" in YT:

    https://www.youtube.com/watch?v=cl_mSH6ZCqw

    https://www.youtube.com/watch?v=IuVkfFFuSfw

    Here's a version in 720p60:

    Yes there are videos on yt, but they are interlaced and without properly color correction sadly, what i need, is the source file

    All those videos look like they were sourced from ep speed VHS. The color in terms of saturation and hue do not seem that bad.
    What are you trying to do?
