    I have tried using Avisynth with despot and descratch. I create the script, load it into Virtualdub then save as with full procesing and the output is untouched.

    Here is my clip:

    Can someone create a script to clean this up? I don't know how to use Avisynth at all. I tried in the past and gave up but want to learn it for advanced filtering. Time to switch to the dark side.

    A 28M file at 28.9kbps? You must be joking.
    ICBM target coordinates:
    26 14' 10.16"N -- 80 16' 0.91"W

    Yes, it's a very small file for 90% of the people. Who uses dialup????

    It's not me. I'm on a T-10 line hookup. The low tranfer rate is from YOUR end.

    OH! oops. My bad. It wouldn't take that long anyway. You want a smaller segment?

    I moved it to another server which is faster. It only took 12 minutes and 13 seconds to download on the slow one.

    You could just post your Avisynth script and you might get more responses.

    I tried the example scripts from the Despot site which did nothing to the footage.

    I just did a simple load of the despot filter with no settings and it did nothing. Deleted the AVS files I created. Never had much luck with Avisynth.

  9. Here is a script I use for CCE. It uses Despot and DePan together, for motion compensation. You will have to change width/height settings for Despot, to match the noise in your video. This is for interlaced video.


    Code:
    AviSource("c:\filename.avi")
    LoadPlugin("c:\program files\avisynth\plugins\despot.dll")
    LoadPlugin("c:\program files\avisynth\plugins\depan.dll")
    LoadPlugin("c:\Program Files\avisynth\plugins\Convolution3d.dll")
    #
    # Assume Bottom Field First
    AssumeBFF()
    # ConvertToYV12(interlaced=true)
    v=ConvertToYV12(interlaced=true)
    #
    # Separate Fields from Frame
    SeparateFields()
    #
    # Use to show before/after comparisons in VirtualDub
    Crop(0,0,720,288)
    i = last
    #
    # Makes 3 copies of each frame for motion compensation
    d = DePanEstimate(v,range=1, trust=3, log="depan.log")
    DePanInterleave(v,data=d, prev=1, next=1, matchfields=false)
    #
    # Despot - remove noise
    DeSpot(p1=24, p2=12, pwidth=20, pheight=4, mthres=20, motpn=true, dilate=1, seg=2)
    #
    # Recover original frame
    SelectEvery(3, 1)
    #
    # Place additional filters here after SelectEvery() function
    # convolution3D Low Quality
    odd=SelectOdd.Convolution3D (0, 6, 10, 6, 8, 2.8, 0)
    evn=SelectEven.Convolution3D (0, 6, 10, 6, 8, 2.8, 0)
    #
    #
    # convert to yuy2 for cinema craft encoder
    converttoyuy2()
    #
    # Interleave for Convolution3D
    Interleave(evn,odd)
    #
    # Combine both fields back into a frame
    weave()
    #
    # Use to show before/after comparisons in VirtualDub
    StackVertical(i, last)

    I get an error saying :

    Weave: Weave should be applied on field based material: use AssumeFieldBAse() beforehand.

    Line 41.

    This is interlaced NTSC material. Not sure what the error means.
