Help Restoring Old Anime to High Definition with comparison video file

[xonathan]

Hello everyone. I've been experimenting with avisynth scripts to restore old anime from DVD's. I need help with one of my projects. I have a DVD from an OVA that I want to restore so it looks like a Blu-Ray remaster as much as humanly possible. I've attached a sample of the anime from the iso using MakeMKV I want to restore in the “test” file here: https://www.mediafire.com/file/3jqtyhsv ... t.mkv/file

The same director from that DVD made an earlier OVA that has a similar look that was remastered into Blu-Ray. I've attached a sample of that anime in the “remaster” file here: https://www.mediafire.com/file/hqrk03oq ... r.mkv/file

In other words, I want to restore through filters the “test” file to look as the “remaster” file as much as possible. Both files contain scenes I've spliced that are representative of the whole OVA's. I've been using TFM, spline36resize, aWarpSharp, Hysteria, Deen, MSSharpen, and LSFmod to accomplish this but I want to know if there are other options. What do you suggest? Thanks

Thank you. I have already reviewed the guides on this page. I guess I was wondering if there's anything else that I'm missing other than the filters I'm already using. Thanks again.

There are a lot more filters out there that the guides don't cover, the guides are just a jumping off point, the rest unfortunately will be searching and trial & error as there is no one size fits all solution for cleaning up old footage. The Doom9 forum might be a good place to start if you are looking for alternative solutions for specific issues.

I have recently been looking into AI upscaling, and it seems fairly promising.
Here are some results I got in just a couple minutes:

The easiest way to get started is to get cupscale and then download some models.
Models can be found on this discord server: https://discord.gg/wnCpXpz
I used the "Big Oldies" model for these examples.

It will be very important to make sure you have good IVTC prior to trying to upscale it. I see there is a lot of frame blends with default settings for TFM, so you will want to spend some time trying to get that aspect of it as good as possible.

By the way... this is really slow.

Thank you. For ITVC I'm using:

TFM(slow=2, pp=5, clip2=(TDeint(src, mode=2, type=3)))
TDecimate()
vinverse()

I've tried everyone combination of mode and pp in TFM but 1 and 5 gave me the "best" combo. I still see blended fields on anything I try. I would welcome any recommendation. I'll give cupscale a try. Thanks
