Hi! First post written here but many read, up till now
I used to work with FCP 10 years ago on Mac and now I am trying to understand Avisynth+ and Premiere pro on Win10 for a project of restoring, editing (noise, color, few titles, audio editing) and archiving old VHS theater shows. This short example was captured from JVC HR-S9850 via IOdata gvUSB2, Amarectv-UTvideo ULY2 loosless. Final file will be MP4 and probably copy of it in ULY2 for a possible future needs.

Most of VHSs are in better quality then this one but I have to do my best on it and I am stuck.
Those horizontal lines and blurry faces are ugly but I don't know how to address them if possible. It seems to me like an copy of copy artifacts but maybe I am wrong, my knowledge of Avisynth+ and filters is very limited (music is my field).. Can someone with better experience give some advice on it?

Working on PAL, 720x576

I tried to do something with this script :
SetFilterMTMode ("QTGMC", 2)
FFmpegSource2("GRode.avi", atrack=1)
AssumeTFF()
QTGMC(Preset="Super Fast", Sharpness=1.0, EdiThreads=2)
Lanczos4Resize(720,576)
Crop(0,2, 0, -12)
AddBorders(0,2, 0,12)
Prefetch(4)

Thank you all!
Svrle

It's more about the noise if you ask me, that's a task NeatVideo V5 will like

Thank you themaster1! I downloaded the Neatvideo demo few days ago and I am trying my best but it is hard to take "the noise" and leave the faces recognizable in this thick capture case. No much detail- free space to set the profile correctly. Pls check the attached video example with this script and neatvideo.

Code:
SetFilterMTMode ("QTGMC", 2)
FFmpegSource2("GRode.avi")
AssumeTFF()
#ChromaShiftSP(X=-2, Y=-2)
QTGMC(Preset="Draft", Sharpness=1.0, EdiThreads=2)
Lanczos4Resize(720,576)
Crop(14,14, -14, -14)
AddBorders(14,14,14,14)
Prefetch(4)
Color advice? Sharpening maybe?.. Thanks

There is an easy trick to get the most out neat. Upsizing x2 before messing with it.
Deinterlace (lossless mode)+ upsize ×2+neatv5+ sharpening
That should be a good formula imo

The first thing I can see is that your VCR doesn't have a built-in TBC.

OK but will a built in TBC deal with this particular horizontal lines issue?

Thanks themaster1, Have to try that one, any particular filters, Avisynth scrypt maybe? For the neat video I go to premiere pro where my demo is.. Thanks

Hi traal. As I mentioned before my VCR is JVC HR-S9850 with a built in TBC and my examples above were captured with it.. I tried many different options (with and without), this one that I post now is WITHOUT TBC but with Stabilizer instead. No processing were made on it, bottom overscan looks better IMO.. Looking for your opinion, thanks

This one is same like above (no TBC, Stabilizator instead + script+ neat video). Lines are now better but faces are blurry..

Code:
SetFilterMTMode ("QTGMC", 2)
FFmpegSource2("GrodeSTABshort.avi")
AssumeTFF()
#vsCnr2_vsCnr2(mode="oxx", scdthr=10.0, ln=35, lm=192, un=47, um=255, vn=47, vm=255, sceneChroma=false)
#ChromaShiftSP(X=-2, Y=-2)
QTGMC(Preset="Super Fast", Sharpness=1.0, EdiThreads=2)
Lanczos4Resize(720,576)
Crop(14,14, -14, -14)
AddBorders(14,14,14,14)
Prefetch(4)
Thanks

-- merged --

Any idea what I can do about the clearness of the faces in this kind of video (and I have to deal with many theater shows like this with old fashion cameras far away). Is it possible to improve it?

Maybe some small avisynth script ?

Thank you very much
