Despot plugin does not work at all

[Umen Pich]

Hi there,
A quick search shows that there were no discussions on Despot Avisynth plugin recently.
I wonder if there is another method to remove spots or nobody cares anymore.

Here is a link to a clip of mine http://www.mediafire.com/?g9ex0567vtucrgd (22Mb only)

There you can see a lot of white and black spots (mainly white) in almost every frame. Fortunately every spot appears for one frame only.
So I gave Fizick's DeSpot a try, but .. suprise... it seems to not work at all ! Even for small spots on a flat surface (wall) which lacks other details.

here is the line I tried : DeSpot(p1=35, p2=14, interlaced=false, pwidth=20, pheight=20, mthres=25)

(yes, off course I loaded the DLL first

Any ideas ?

Thanks a lot !

This removes most of them:

function RemoveSpots(clip input, bool "_grey", int "repmode") 
{
    _grey=default(_grey, false)
    repmode=default(repmode, 16)
    clmode=17
    clensed=Clense(input, grey=_grey, cache=4)
    sbegin = ForwardClense(input, grey=_grey, cache=-1)
    send = BackwardClense(input, grey=_grey, cache=-1)
    alt=Repair(SCSelect(input, sbegin, send, clensed, debug=true), input, mode=repmode, modeU = _grey ? -1 : repmode ) 
    restore=Repair(clensed, input, mode=repmode, modeU = _grey ? -1 : repmode)
    corrected=RestoreMotionBlocks(clensed, restore, neighbour=input, alternative=alt, gmthreshold=70, dist=1, dmode=2, debug=false, noise=10, noisy=12, grey=_grey)
    return corrected
}

AviSource("example.avi") 
ConvertToyV12()
RemoveSpots()

A modification of RemoveDirt(). Unfortunately, some of the worst ones (frames 63 and 96) are still there.

You should be capturing and compressing as YUY2, not RGB. You have some AGC problems too.

jagabo,
That worked !
Thanks a lot !

My Name Is Firas, I am a new memberand I want your help for the best program or filter to remove
spots of my Video, I have spend All the last time searching for which is the best prorgram or despot filters but i have no results. I was try Spotremover for Virtualdub with (no_dups_with_SpotRemover) Code but it's not work at all. I tried to use the code by (jagabo) but I am not Sure that I have use it Correctly.
please help me by your knowlage to give me advice "whats is the best choise does U use". thanks Alot For you are reading this massage

[jagabo]

Upload a sample of your video.

[the Prodigy]

thank for you reply, my videos quality is same as Umen Pich's video (Example) http://www.mediafire.com/?g9ex0567vtucrgd its an old movies

[the Prodigy]

how I can use the code:



function RemoveSpots(clip input, bool "_grey", int "repmode")
{
_grey=default(_grey, false)
repmode=default(repmode, 16)
clmode=17
clensed=Clense(input, grey=_grey, cache=4)
sbegin = ForwardClense(input, grey=_grey, cache=-1)
send = BackwardClense(input, grey=_grey, cache=-1)
alt=Repair(SCSelect(input, sbegin, send, clensed, debug=true), input, mode=repmode, modeU = _grey ? -1 : repmode )
restore=Repair(clensed, input, mode=repmode, modeU = _grey ? -1 : repmode)
corrected=RestoreMotionBlocks(clensed, restore, neighbour=input, alternative=alt, gmthreshold=70, dist=1, dmode=2, debug=false, noise=10, noisy=12, grey=_grey)
return corrected
}

AviSource("example.avi")
ConvertToyV12()
RemoveSpots()



and which program I have to use?

[jagabo]

What exactly is the problem you're having? Are you familiar with how AviSynth works?

RemoveSpots() got rid of most of the small spots in your sample. It left some big spots in frames 63, 71, and 96. You could try playing with the RemoveSpots() parameters but I used ReplaceFramesMC() instead to interpolate a new frame from the frames before and after:

function RemoveSpots(clip input, bool "_grey", int "repmode") 
{
    _grey=default(_grey, false)
    repmode=default(repmode, 16)
    clmode=17
    clensed=Clense(input, grey=_grey, cache=4)
    sbegin = ForwardClense(input, grey=_grey, cache=-1)
    send = BackwardClense(input, grey=_grey, cache=-1)
    alt=Repair(SCSelect(input, sbegin, send, clensed, debug=true), input, mode=repmode, modeU = _grey ? -1 : repmode ) 
    restore=Repair(clensed, input, mode=repmode, modeU = _grey ? -1 : repmode)
    corrected=RestoreMotionBlocks(clensed, restore, neighbour=input, alternative=alt, gmthreshold=70, dist=1, dmode=2, debug=false, noise=10, noisy=12, grey=_grey)
    return corrected
}

function ReplaceFramesMC(clip Source, int N, int X)
{
    # N is number of the 1st frame in Source that needs replacing. 
    # X is total number of frames to replace
    #e.g. RX(101, 5) would replace 101,102,103,104,105 , by using 100 and 106 as reference points for mflowfps interpolation
 
    start=Source.trim(N-1,-1) #one good frame before, used for interpolation reference point
    end=Source.trim(N+X,-1) #one good frame after, used for interpolation reference point
 
    start+end
    AssumeFPS(1) #temporarily FPS=1 to use mflowfps
  
    super = MSuper()
    backward_vec = MAnalyse(super, isb = true)
    forward_vec = MAnalyse(super, isb = false)
    MFlowFps(super, backward_vec, forward_vec, blend=false, num=X+1, den=1) #num=X+1
    AssumeFPS(FrameRate(Source)) #return back to normal source framerate for joining
    Trim(1, framecount-1) #trim ends, leaving replacement frames
  
    Source.trim(0,-N) ++ last ++ Source.trim(N+X+1,0)
}

AviSource("example.avi")
ConvertToYV12() #RemoveSpots() requires YV12
RemoveSpots()
ReplaceFramesMC(63,1)
ReplaceFramesMC(71,1)
ReplaceFramesMC(96,1)

You'll need to download and install all the filters those function rely on (maybe others):

http://avisynth.org.ru/mvtools/mvtools.html
http://home.arcor.de/kassandro/RemoveDirt/RemoveDirt.htm

You still have a problem with color and brightness wandering around. But that's probably better addressed in another thread.

[the Prodigy]

thanks A lot
but can you tell me from step 1 what I have to do please

[the Prodigy]

after I have Download MVTools v.1.11.4.5 and take code above and compressed it by Avisynth as YUY2. What I have to do then?

[poisondeathray]

It will be uncompressed YUY2, so then you usually feed the script to an encoder. It depends on the final format goal you desire

If you don't know how to use avisynth , read the beginners' guide
http://avisynth.org/mediawiki/Main_Page
http://avisynth.org/mediawiki/First_script
http://avisynth.org/mediawiki/Getting_started

[the Prodigy]

I have not understand any idea can you tell me the step to get a video without a spots please?

[jagabo]

This is not a good project for beginners because of the complexity of the script and the assortment of third party filters used. But here are the basic steps:

1) Install AviSynth.

2) Downloaded the other filters I listed. Open the archives and copy mvtools2.dll and RemoveDirt.dll to AviSynth's Plugins folder. Some other filters may be required but I don't know what they might be. If you get an error message later on it will tell you what filter is missing.

3) Use Notepad to make a text file with the script I listed above. Change the extension of the file from .TXT to .AVS. If your AVI file has a different name change the script to use that name. Or rename the file to match the script. If you don't use the exact same file as your sample the ReplaceFramesMC() lines will have to change to match the frames that need replacing.

4) Open the AVS file with a video editor or encoder. VirtualDub is a good program to use to test your AVS scripts. Use File -> Open Video File to open the AVS script. If all is working properly you can encode.

[lordsmurf]

This is not a good project for beginners

Agreed.

[the Prodigy]

Thanks a lot for your advice.
I did what did you tell me exactly:
1 . I Intalled AviSynth.
2 . I downloaded the filters (mvtools2.dll and RemoveDirt.dll) and many others dll, and I copied them to AviSynth's plugins folder.
3 . I used Notepad to make a text file with the script that you listed above as AVS file, and I did what is the correct for names to match the script as you Explain above.
4 . I opened AVS file, Then I opened VitrualDub Program with Spotremover 355 filter with the video of Course.

But Actualy it doesn't work!... What I have to do?
Here is two samples of my videos.

[jagabo]

Spot removers won't work on those videos because they have been through extremely strong temporal filters. Spot removers work by looking for spots that occur on only one frame. The temporal filter used on those clips has caused the spots to span several frames (ie each frame of the video is a combination of several of the original film frames).

[the Prodigy]

that's meane I have to open AVS File then I have to open VertualDub Program and play the video, then Export it. is that Right?

[jagabo]

First of all, you don't need the AviSynth script if you're going to use the SpotRemover plugin in VirtualDub (although using both might remove more spots).

If you're going to use VirtualDub to encode your video (using an AviSynth script or not) you set up whatever filters you want, set up the compression codecs, then File -> Save as AVI. If you're going to use another encoder you just treat the AviSynth script as if it was a video file and supply that to the other encoder. For example, with the x264 CLI encoder:

x264 --crf 18 --output filename.mkv filename.avs

Finally, as noted, those spot remover plugins will not work with your video.

[the Prodigy]

No, I won't use spotremover filter Any more because it's useless with this videos as all the last time I have been use It, I will only use virtualDub With AVS Script as I see It's results.

[the Prodigy]

I tried this way but also It doesn't work, maybe because of incomplete the (*.dll) plugins Inside AviSynth plugins folder. I have (mvtools2.dll , RemoveDirt.dll and RemoveDirtS.dll). and I'm sure about them, because you tell me to download them. But what about the others (*.dll), Once you tell me there is anothers and maybe you will receive a massage about them but I didn't. Thanks for your kind...

When you open the AVS in VirtualDub (use File -> Open Video File..., not File -> Run Script...) you should get a message about what filter is missing. You use that information to track down what filters you need to download and install.

But once again, you're wasting your time with these particular videos. The AviSynth filters aren't going to remove the spots either.

[the Prodigy]

AHA... Is there another way to remove this spots?

[jagabo]

You need to get back to the original video -- before it's been through the temporal filter. Otherwise, I don't see any way to fix them unless you are willing to paint the frames by hand. Or write a very long script to copy bits of other frames to cover up each individual spot.

[the Prodigy]

there is no original video, the way of scripts is difficult for me, and I'm ready for the manualy way but how?

[poisondeathray]

"manually" means painting frame by frame and cleaning up the spots e.g. in photoshop or after effects

you can copy parts of "clean" frames to cover up spots on "dirty" frames , but sometimes there are areas where there is no "good" frame to derive information from, and you have to reconstruct it almost from scratch

This is a lot of tedious work

[the Prodigy]

Hi Everyone, I have a problem to loading AVS script with Virtualdub for removing a spots, when I tried to run AVS File with the Encoder an Error massage appeared "there is no function of Clense" that's meanes there is a missing .dll, Is That Right? Could any body help me with URLs please?

[poisondeathray]

I think cleanse comes with one of the removegrain filters (there are a few). Unfortunately I can't recall exactly which version is the required one . It might be 1.0b

Unfortunately its not work and there is same Error massage> Maybe because of using this code for spot removing:

function RemoveSpots(clip input, bool "_grey", int "repmode")
{
_grey=default(_grey, false)
repmode=default(repmode, 16)
clmode=17
clensed=Clense(input, grey=_grey, cache=4)
sbegin = ForwardClense(input, grey=_grey, cache=-1)
send = BackwardClense(input, grey=_grey, cache=-1)
alt=Repair(SCSelect(input, sbegin, send, clensed, debug=true), input, mode=repmode, modeU = _grey ? -1 : repmode )
restore=Repair(clensed, input, mode=repmode, modeU = _grey ? -1 : repmode)
corrected=RestoreMotionBlocks(clensed, restore, neighbour=input, alternative=alt, gmthreshold=70, dist=1, dmode=2, debug=false, noise=10, noisy=12, grey=_grey)
return corrected
}

function ReplaceFramesMC(clip Source, int N, int X)
{
# N is number of the 1st frame in Source that needs replacing.

[poisondeathray]

But those functions rely on other .dlls. clense is most definitely part of removegrain . Make sure you have removegrain.dll in your plugins folder (I'm not sure which removegrain version)

I think it's this one
http://home.arcor.de/kassandro/RemoveGrain/RemoveGrain.rar

[the Prodigy]

Yes Now maybe its work because it's appeard a new error: there is no function named "SCSelect" How I could pass it?
