I finished the project. The attached photo shows the same frame as in my post #1, but with the improved version on the right.

I ended up using Defreq, and got some help with the settings from "jagabo" over in the Videohelp.com forum. Here is the script I used:

Code:
loadPlugin("C:\Program Files\AviSynth 2.5\plugins\defreq.dll")
AVISource("E:\fs.avi").KillAudio().converttoYV12(interlaced=true).AssumeTFF()
tfm()
source = tdecimate(cycle=10,cycleR=2)
TurnRight(source)
defreq(fx=16.6, fy=0.0, dx=2, dy=2, sharp=0, info=false, show=0)
defreq(fx=49.4, fy=0, dx=2, dy=1, sharp=0, info=false, show=0)
TurnLeft()
output = aWarpSharp(depth=5).Sharpen(0.3)
return output

#Alternate output, for debugging
#interleave (source,output)
#stackhorizontal (source,output)
I also did some dirt removal, stabilization, some additional sharpening, and color correction, the last one in order to reduce the reddish hue.

It's not perfect (you'll see some residual banding, if you look for it, but it is a LOT easier to watch.

Impossible for each professional studio in the world to my knowledge. Can only be done with avisynth and always experimenting, developing, learning. Looks really great!

Nice job John/Jagabo, the client will likely be most happy.

StainlessS, the color correction was done with GamMac.

Well done, John! Avisynth once again proved to be the best frameserver to tackle these things

there are one from 2007 https://github.com/realfinder/Univer.../25/defreq.dll I think it's from http://members.optusnet.com.au/squid_80/defreq64.zip

it's work but it's better if someone did update it to new color formats and HBD

Impressive work John, out of curiosity, did you try to remove the residual banding? My impression is that residual is similar to residual combing, which I often see in YT videos and got me irritated & frustrated to remove that residual combing. Sadly those videos are from some official club football youtube channel, I guess they just don't care to properly edit/process their videos. This issue is typically found in some old footage, which I bet they were from interlaced sources.

Confession: I'll have to "blame" you guys for the change of my taste , because the more I follow these avisynth threads, the more obvious errors/mistreatment of those videos and I can't stand them anymore hence I have to do something just to be able to watch the damn video. Thank you guys for this.

There was a LOT of residual banding, mostly at the top and the bottom. This was probably due to the bars not being the same distance across the frame. Also there was a discontinuity in the center of the frame. This caused a slight vertical band of residual "stuff," although as you can see from the frame capture, this is pretty subtle.

If this had been for a paying customer rather than for a friend who does volunteer work for NFL Films (he finds one-of-a-kind old game films) I would have done more work.

The only thing that I was a little disappointed with was the GamMac color correction. It is a very useful tool, but I have never figured out how to tune it. I think the result was just a tad too blue. I probably should have left it with the slightly warm (too red) color.

If exists residual combing vinverse (not vinverse2) maybe is a good solution.

First image here [Bot RHS] : https://forum.doom9.org/showthread.p...ghlight=Gammac
Has BluMul set at 0.95, you can see effect compare to the image above it.
[maybe a tad more reduction would be better for that image].
Theres also a lot of green [the default lockchan] in both images, and both are a bit blue.
[ I'm lousy at color correction, look great when I do it, next day looks awful ]

EDIT:
Some wildlife from around here john, [no cougars in this neck of the woods],
4 remaining out of clutch of 9 [EDIT: Gaggle of 9]
