How to fix blurry video on Avidemux

[Sharc]

@satimis
Off the record, if you still don't succeed: Maybe you should just start with a very basic script rather than getting lost in the plugins jungle.

Just use this single line of your script (comment the rest out using # as the first character of each line you want to skip)

Mpeg2Source("C:\....path to your .d2v")

and see whether it opens in Vdub2 (or AvsPmod).

[satimis]

nnedi3.dll is for w7. What shall I do ?

Copy (move) it to the plugins64+ folder.

Already done

[satimis]

Also the Zs_RF_Shared.avsi as seen in your first image in post #106 above is over 700KB.
The real Zs_RF_Shared.avsi is only 100KB. Perhaps you should open that in Notepad also and check it

Here it is

[Sharc]

Already done

ok. Now proceed according post#119.
If it still fails proceed according post #121.

Create a single line script named test_script.avs

Mpeg2source("C:\Users\satim\Downloads\may_home_orig.d2v")

It works

#119
still fail

#121
It works. Pls see #125

[Sharc]

ok.
Now same as #121 but remove the # in front of the QTGMC(....) line of the script and try again.
This will show whether the QTGMC(....) is working or not.

[satimis]

ok.
..... remove the # in front of the QTGMC(....) line of the script and try again.
This will show whether the QTGMC(....) is working or not.

There is no # before QTGMC(....) line

[Sharc]

I said same as #121 or #125, i.e. with all #, except the Mpeg2Source line.
Now remove the # in front of QTGMC and leave the rest with #.
So remains a simplified script like

Mpeg2Source("......")
QTGMC(.....)

and all the rest is still with # (means ignore)

This will show whether the QTGMC is working or not.

If it works you can take the next step and remove the # in front of the SMDegrain(....) and so on. Step by Step, until it fails again.

No complaint

Uncomment following line, popup complaint

SMDegrain (tr=9, thSAD=500, refinemotion=false, contrasharp=false, PreFilter=4, mode=0, truemotion=true, plane=4, chroma=true)

[Sharc]

Very good. So QTGMC is working now, and the remaining problem is with SMDegrain() and/or KNLMeansCL.
Maybe somone else can chime in and suggest a working combo of these.

Edit:
I still don't see the KNLMeansCL.dll in your plugins64+ folder. See my post #119 where I attached it.

[jagabo]

Looks like qtgmc.avsi is bad.
Open it in Notepad and post the top 30 lines to the thread here
The real qtgmc.avsi is not 500KB as is seen in your image above

screenshot attached

For future reference, saving qtgmc.avsi from github is a little tricky. From the web page pictured right click on the Raw button and select Save As (or Save Link As, depending on what browser you're using) from the context menu.

If you do that from the download link at the avisynth.nl page you will save an HTML page that displays the qtgmc.avsi text, not the actual qtgmc.avsi file. You probably made the same mistatke with Zs_RF_Shared.avsi.

I don't see KNLMeansCL.dll in the most recent image of your plugins64+ folder. Or in the call to SMDegrain you can use use PreFilter=3 instead of 4 (so it doesn't try to use KNLMeansCL).

Yes, I attached the KNLMeansCL.dll in post #119. Apparently it did not find its way to the plugins64+ folder, or has been removed .....

I always download packages in following way;

For example;
https://github.com/pinterf/masktools/releases

Right click

masktools2_v2.2.30.7z

-> Save link as

then save the package to my selected folder.

Do you have the requirements for KNLMeansCL?
https://github.com/Khanattila/KNLMeansCL/wiki/Requirements

[jagabo]

Once again, changing PreFilter to a value less than 4 will eliminate the need for KNLMeansCL. The lower PreFilter value won't make much difference with your video.

Did you mean on script.avs

On following line

SMDegrain (tr=9, thSAD=500, refinemotion=false, contrasharp=false, PreFilter=4, mode=0, truemotion=true, plane=4, chroma=true)

Change;
PreFilter=4
To
PreFilter=3 ???

[Sharc]

Change;
PreFilter=4
To
PreFilter=3 ???

Yes.

Also, I think the variableblur.dll is missing in your plugins64+ folder. It is required for BinomialBlur().
Here it is, just in case:

[jagabo]

Ah, yes. I forgot about the use of BinomialBlur() in my UnSharpMask().

[satimis]

Change;
PreFilter=4
To
PreFilter=3 ???

Yes.

Performed following steps:

1)
Change;
PreFilter=4
To
PreFilter=3

2)
Download -> Extract -> variableblur.zip -> copy variableblur.dll -> Plugin64+

Now it works without complaint, showing 2 photos, side-by-side

Remark: PreFilter=4 can't work

What will be the next steps? Thanks

[jagabo]

Did you install Microsoft Visual C++ runtime Redistributable Package for Visual Studio 2015, and the AMD APP SDK v2.6 as indicated in the KNLMeans requirements?

https://github.com/Khanattila/KNLMeansCL/wiki/Requirements

Those are Windows system libraries, not an AviSynth dlls.

As PreFilter=3 is working I would not worry much about KNLMeansCL (PreFilter=4) not working for now. You could tackle this later. It's not critical for your work.

It is now working displaying video on VirtualDub2 screen without problem. I'm waiting for jagabo's advice to run his script.

Meanwhile I'm collecting info and downloading essential packages for learning VirtualDub2 to restore VHS video as well as scripting .

I'll clone a new Windows 10 64bits for this test

6 Packages to be installed on Win10:-

AviSynth+  (AviSynthPlus_3.7.0_20210111_vcredist.exe)
VirtualDub2  (VirtualDub2_44282.zip)
AvsPmod  (AvsPmod_v2.6.9.8_.Windows_x86-64.zip)
WinFF  (WinFF-1.5.5-Setup.exe)
FFmpeg  (ffmpeg-2022-03-03-git-72684d2c2d-essentials_build.7z)
MediaInfo  (MediaInfo_GUI_21.09_Windows.exe)

Any comment and suggestion? Thanks.

The pictures in VirtualDub2 which you see are already processed with jagabo's script! What you see there is your fixed source, fixed by the script. There is no purpose in "running this script" as it is already in effect.
You can just encode it now to produce the fixed video file. See post #74:
https://forum.videohelp.com/threads/403343-How-to-fix-blurry-video-on-Avidemux/page3#post2650088

The script is pretty slow, so encoding will take time. You can experimentally speed it up by changing in SMDegrain(tr=3,..........)

And don't overdo with installing and piling up all kind of SW without a clear purpose.

The path is;
Mpeg2source("C:\Users\satim\Downloads\may_home_ori g.d2v")

orig = original

Before I have trimmed a section on the original video and name the trimmed section as "may_home_orig.vob". I couldn't recall whether later re-named it as "may_home_orig.d2v"

Anyway I can't trim another new section on the original .vob video testing his script

And don't overdo with installing and piling up all kind of SW without a purpose.

I don't think one script (parameter/setting) able to work on the whole .vob video because the video were captured on different scenes. Videos captured outdoor/nature are not bad, quite clear. Only those videos captured indoor are unclear.

I have trimmed the videos on DVD ripped from VHS tapes into 27 sections, running ffmpeg. The trimmed sections are untouched, same as the original .vob. I'm prepared to do the quality enhancement on the newly cloned Win10 VM.

You can't just rename a .vob to .d2v. The .d2v must always be created by DGIndex.
Anyway, good luck with your experiments. I can't help much with W10 VM I am afraid.
