How can I fix Video ?

[Sqlfox]

Hello, I want to fix and Restoration this video, what should I do?


can you help me please thank you

SpotLess+SCUNet:

SpotLess+MCTemporalDenoise:

or other filter can help the 'normal' artifacts somewhat.
About the distortion at the bottom: you need to recapture (I do not see a way to fix it through filtering)

[The_Doman]

If there is so much (consistent) tracking noise and you have no option to recapture it better, you can cut the static away and fill/re-center the picture.

Something like this for example:

Add borders to make the video original size again:

So, which program's progress are you talking about?

[Alwyn]

Here's my attempt, using Virtual Dub2-64bit for resizing to 4:3 (assuming it is that), denoising with Camcorder Colour Denoiser and Neat Video (which is a paid plugin), Mercalli (paid-program) for stabilisation and Magix Movie Studio for per-scene cropping (to remove bottom static) and export. File DAR is 1:1 (1440x1026). Bitrate can be cranked up if desired.

Doesn't seem like there is much improvement?

What improvement specifically are you hoping for? You should be able to articulate it,
at least - for example, It could be sharpness, noise, color saturation, brightness/contrast, stabilization and more

disappearance of space in faces sharpness

disappearance of space in faces sharpness

Not sure what this means.

The source is small, and there are a lot of artifacts. If you have the tape, perhaps you should capture it again.
Any typical attempt at improving it is a compromise, because when you remove the noise and fuzziness,
you start to also remove the details, and there aren't that many to begin with.
Here's a try using Avisynth and Vdub2
Selur's first example above looks pretty good, perhaps he can encode it for you

[Alwyn]

That's not bad Dave, what's your script?

[davexnet]

That's not bad Dave, what's your script?

The script is very simple; I tried a few other things, MosquitoNR, Santiag, etc. but it didn't help

vid=lwlibavvideosource("C:\Users\davex\Downloads\ese.mp4")
aud=lwlibavaudiosource("C:\Users\davex\Downloads\ese.mp4")
audiodub(vid,aud)
a=trim(0,848)
b=trim(1119,0)
a+b
#
spline64resize(640,480)
crop(8,0,-0,-36)
hqdn3d(6.5)

[Alwyn]

Thanks Dave, I'd never heard of hqdn.

[davexnet]

Thanks Dave, I'd never heard of hqdn.

it's a temporal/spatial noise reducer, with separate luma and chroma strengths.
It's fast, quite good for this kind of work

[Alwyn]

Just tried it, looks good. I put VDub CCD on top of it and it is even better.

Interesting, I never tried that, but I've used cnr2 in the past. Isn't it similar, chroma cleaner?

[Alwyn]

Can't tell, but sounds like it. I tried vsCNR2 but had no luck; using "cnr2" in the script as per the wiki but it wouldn't work, "no function named cnr2".

[davexnet]

Yeah I see. Looks like vsCNR2 is the updated replacement, but the old one
is still good
http://avisynth.nl/index.php/Cnr2

[Alwyn]

Arrgh, I think there's a bug in the vsCNR2 wiki. The example shows "cnr2" but you need to type "vscnr2".

CCD is still making an noticeable improvement after vscnr2.

[davexnet]

I see that. I found it in my vdf archive; it cleans up the chroma noise pretty good, and also stabilizes the saturation.
Good find.
It converts to RGB32, but I don't think doing it once is too much of a hit.

fwiw, one more variant

trim(0,848) + trim(1100, 1952)
crop(8,2,-0,-24).spline36resize(400,300)

Dehalo_alpha(rx=2.1, ry=1.6, darkstr=0.6, brightstr=1.0)
SMDegrain(tr=5,thSAD=1000,contrasharp=50,prefilter=3,refinemotion=true,LFR=false)
Adaptive_Sharpen(0.8)
FineDehalo()

Thank you everyone for your valuable information.

This feature is nice, but it starts to blur when viewing from the right or from above

[Alwyn]

Good find.

I'm only a fan of CCD because LS is a fan!

It's just stabilizer - it's either some filler (blur/mirror), black void, or you have to use crop. Or you can choose don't stabilize at all. There is no ideal solution

[Sqlfox]

Can you recommend the necessary filter and program?

I do not recommend hq3dn. I used it for a while until I realized that it made dark videos terribly dark. (E.g. a room with the lights off, dark figures, and the bright spots are small light bulbs).

Then don't apply it to dark areas.

[Sqlfox]

Absolutely very good. If you write the settings program and filter you use, I can start encoding.

Thank you for your valuable time

convertbits(16).converttoyuv444
QTGMC(preset="slower", InputType=1, TR2=3) <-- but may not be useful (check)
TemporalDegrain2(degrainTR=3, grainLevel=2) <-- you can try other values, there is room for improvement here.

Save in VDub as Lagarith 4:4:4 YCbCr 16-bit, limited Rec601.

Next step VEAI, but this is a commercial software. Upscale 2x + Chronos 50fps + Artemis/low quality filter.

Optionally remove shakes with Deshaker v3.1 (Vdub plugin).

The video would be smoother, but there are a lot of duplicate frames. They can be removed in VDub.
