Can I come to restore this video?

[johnmeyer]

Is there a way to make it a real HD?

As others have said: you must be making a bad joke. That video is not even decent standard definition quality.

[jagabo]

You can enlarge the frame while keeping sharp, smooth edges. But there's no detail between those edges. People look like mannequins (or worse), everything else looks like plastic, or a bad oil painting. This sort of technique works for cartoons but not well for real world video. Especially the extreme settings needed for badly damaged video.

LSmashVideoSource("C:\Users\John\Downloads\F1 1994 Highlights.mp4")
Santiag()
QTGMC(InputType=1)
McTemporalDenoise(settings="low", AGstr=0.0) 
MergeChroma(last, aWarpSharp(depth=20))
nnedi3_rpow2(4, cshift="Spline36Resize", fwidth=1920, fheight=1080) 
ColorMatrix(mode="Rec.601->Rec.709")
aWarpSharp(depth=10)
Sharpen(0.5)

Although it's sharper than then original (when both are played full screen) it looks worse overall.

Thank you so much, it seemed like a miracle with the highlights of '94! Now I would have a video even worse, and trying that script, I will not solve anything, would you have any advice?

I used the script settings to the maximum, but still it was very blocking and the colors also need to be improved. Can someone help me?

[jagabo]

You need to use a deblocking filter to remove blocks. LIke deblock_qed() at very high settings.

[ciccioschumacher]

Thanks, and for the colors?

[jagabo]

A little white balance with ConvertToRGB(matrix="pc.601").RGBAdjust(r=0.96, b=1.13).ConvertToYV12(matrix="PC.601"). Maybe turn the saturation down a bit. Convert to rec.709 if you're going to upscale.

[ciccioschumacher]

What are the "very high" settings for "deblock_qed()"?

[LMotlow]

There is no "very high" setting for that plugin. The deblock strength is adjusted with the Quant1 and Quant2 settings. The defaults are quant1=24, quant2=26. The max value you can set for either of those is 60. There are additional offset values that can also be adjusted. Look over the documentation, which comes with the plugin download. The paramaterv are also explained on the download page: http://avisynth.nl/index.php/Deblock_QED.

It's telling you exactly what's wrong and how to fix it. Mod4 = integer multiple of 4. For example, 4, 8, 12, 16, 20...

[ciccioschumacher]

I am going crazy!

Maybe if you used your head you'd see. Look at that line 120 and you see you're cropping by 1. That's a serious no-no in AviSynth unless you're in RGB. It doesn't mean the resulting resolution has to be Mod2, but the individual crops themselves have to be Mod2 (multiples of 2).

[ciccioschumacher]

Can you explain what the hell I should do? The video is in 426x240 resolution, how do I make it compatible with MOD4?

[jagabo]

If you need to reduce the width by 2, and can't crop each edge by 1, what else can you do?

[manono]

Can you explain what the hell I should do? The video is in 426x240 resolution, how do I make it compatible with MOD4?

What I do in such situations is use AddBorders to add 2 more so it's Mod4 and then remove those 2 pixels after the filtering with a Crop line.

AddBorders(2,0,0,0)
Filter
Crop(2,0,0,0)

[ciccioschumacher]

Thank you very much! Is it worth it to restore this video? If so, what could I do? https://www.youtube.com/watch?v=OnyOYHha3fg&list=PL201BFC4EE0185452

[jagabo]

Same shit, another day.

This looks better. Some advice?

[jagabo]

Take a look at all the other scripts you've been given. Experiment with them and try to learn something. Then apply that knowledge to other videos.

[ciccioschumacher]

Thank you very much!

This is my work, what do you think?
This is instead the original video: https://youtu.be/OnyOYHha3fg

[LMotlow]

Please don't use YouTube as a source for analyzing your own work. YouTube re-encodes everything. We don't know what you did to your original and we don 't know what YouTube did to it. There is no way to tell their effects from yours. And by the way, your video is posted in a manner that can't be downloaded. There's no way to evaluate video accurately in that tiny web player at YouTube.

[manono]

And by the way, your video is posted in a manner that can't be downloaded.

I don't know about that, as I got it easily enough using 4K Video Downloader. It looked like crap on YouTube before and it still looks like crap on both YouTube and on my computer. What else are we supposed to say?

[LMotlow]

Wouldn't download for me and I don't propose to install even more bloatware on my laptop. But even on the small screen it didn't look so great. Even the levels are a mess.

Attached my work, what do you think?

[Cornucopia]

Things you need to improve on:

Smoother AR changes
Removing exposed frame edge anomalies
Not applying so much deblocking it makes blurring obvious
Avoiding posterization buildup
Improving edit timing for greater flow and audience interest
...
...

[ciccioschumacher]

Thanks so much. Since I am learning, could you send me a script as I have little con fi dence on AviSynth?

[Cornucopia]

No.

These are things you need to become aware of, and change your habits about. One cannot give you a script for awareness, or a script for habit-changing. Time to learn (sometimes, the hard way). To do that, you must attempt your own trial and error.
