VHS Damage - Dropouts & Jitter

[NASS]

Hi everyone, I hope this message finds you well, An incredible job done on this VHS sequence by Chief Mouse,

https://www.youtube.com/watch?v=gClHbBd05QI

Is there an Avisynth script to get a similar result on Dropouts and Jitter?

Thanks in advance for your answers.
Best regards

Very impressive result by Chief Mouse... :scared:

I am not aware of any AviSynth plugins which can get even close to this. I tried VHSClean and FixRipsP2 from this link:

https://forum.doom9.org/showthread.php?p=1996486&highlight=vhsclean

but both tools could not even get close to the result by Chief Mouse. Who is this guy, and which software did he use?

Do you have a sample of your video ?

The bottom is partially cropped and internals are zoomed. So part of damaged bottom is not restored.

The FM-demodulator noise cleaning is median filtering - see MedianBlurTemporal or vsTTempSmooth(pmode=1) with big enough tr.
The stab may be mvtools - depan.
The denoise may be mvtools - MDegrainN.

Hi all:

Perhaps stabilization has been done with a virtualdub plugin named stabbo. It can be used in avisynth:

Loadvirtualdubplugin("E:\Bibliotecas\Mis_programas\_VIDEO\Virtualdub\Last_vdf\Stabbo.vdf","stabbo",1)

any video source...

....

source .stabbo(1, 0, 0, 75, 6, 13, 15, 1, 1, 8, 103, 0, 1200)

I tried using stabbo alone and in different combinations with VHSClean and FixRipsPS, but I never got results even close to the results of Chief Mouse. Especially the last section of the source clip did not get close to the result of Chief Mouse.

So I think that this is it for me. Unless Chief Mouse is willing to share his approach I will close this topic for me...

Especially the last section of the source clip

You interpolate over the "bad" frames first , using good frames as reference points

There are many examples of this posted using mvtools2 based functions and rife

Ideally you'd start with the original source , not the cropped youtube video
