If anyone upscaled a lot of tv series shot on film in 1950s,1960s,1970s from NTSC and PAL dvds (aspect ratio is always 4:3), what Proteus settings do you prefer for batch upscaling? Do you go more than 600p for NTSC and 720p for PAL with Proteus auto/relative to auto? The goal is to cleanup noise/grain and avoid upscaling artifacts. What software do you use for IVTC when NTSC DVDs are hard telecined?
In Topaz do you keep original pixel ratio or choose square pixels when upscaling?
Do you convert mpeg2 to h.264 or h.265 before upscaling?
Try the Nyx model as well. It does a pretty good job at removing noise too. Check out my post here for settings I used to do all my PAL Star Trek dvd’s. You could back off the settings a bit to reduce upscaling artefacts but remember if you are upscaling you are creating pixels that were never there in the first place. Good luck.

Depends on the show, of course.
For a heavy grain 60s show, I found Nyx fast RTA and then Proteus RTA to be the best mix denoising and upscaling without losing too much detail.
I always upscale to FHD with black bars on the sides. Square pixels. Always have Recover original details at 0. Encode to H.265 but software encoded, so not what’s offered by TVAI. I do tiff output in TVAI. I have yet to run into a show that didn’t deinterlace well with the bwdif filter in ffmpeg. Most progressive DVDs just need the -r option in ffmpeg to drop the duplicate frames.
Here’s the settings I used:
“-nyxauto”: “true”,
“-nyxpreblur”: “0”,
“-nyxnoise”: “0.07”,
“-nyxdetails”: “-1”,
“-nyxhalo”: “-1”,
“-nyxblur”: “-1”,
“-nyxcomp”: “-1”,
“-nyxblend”: “0”,
“-protcompression”: “0.25”,
“-protdetails”: “0.01”,
“-protblur”: “0.02”,
“-protnoise”: “0”,
“-prothalo”: “0”,
“-protpreblur”: “0”,
“-protauto”: “true”,
“-blend”: “0”
For another 60s TV show, it wasn’t as grainy so I just used Proteus:
“-protcompression”: “0.13”,
“-protdetails”: “0”,
“-protblur”: “0.08”,
“-protnoise”: “-1”,
“-prothalo”: “-1”,
“-protpreblur”: “0”,
“-protauto”: “true”,
“-blend”: “0”
These were done with a script, so that’s why I’m listing out the settings like this.
Back to what I said at the start, each show turned out best with slight changes in these settings. On newer shows I usually I end up doing Proteus Manual with setting close to these:
“-protcompression”: “0.4”,
“-protdetails”: “0.12”,
“-protblur”: “0”,
“-protnoise”: “0”,
“-prothalo”: “0”,
“-protpreblur”: “0.2”,
But for each show, the setting are good for the whole show usually.
