[Help] "Le Bon, la Brute et le Truand( ("The Good, the Bad and the Ugly") French version

[Beber]

Hey, guys.

I'm currently recreating the French version, international cut, based on the Arrow UHD that I'll tonemap to SDR in Ripbot264 and resize to 1080p.
I already resynchronized the French dts 5.1 from the 4K remastered MGM Blu-ray, except transcoded to PCM stereo. I used the dts HDMA 5.1 from the English version in a few spots for better transitions, also transcoded to PCM stereo. I have a lead on a VHS tape that should include the original mono that I'll try to sync to it as well.
Now for the French parts, I have the opening credits and closing credits from the Arrow bonus section, in fake HD. I also have a French TV recording in fake HD for the credits and characters' nicknames.











Now there's a problem with the end credits: my French recording has a pop-up at the bottom for the next program, and apparently Arrow must have used that same source 'cause they cropped the bottom part and, doing so, the aspect ratio is now wider. So I'll have to zoom in to recover the same black bar thickness as the rest.




Now for the help part: can anybody with the best AI upscale capabilities chime in and try their best at upscaling these fake HD parts? I'll deal with the color matching afterwards so it all blends in the best I can. All I managed to do with built-in AI upscale in Shutter Encoder is this and, although it gives better delineation to the texts, it's seems to smooth the image:





The final product would include the French international version in 1080p with French audio from MGM, possibly VHS and English and audio commentary from Arrow, plus French subtitles from MGM rearranged by myself and English SDH subtitles from Arrow.
