I was on a videohelp forum, explaining i tried making a video progressive, while maintaining the best quality

The file has combing all over the place. It’s in 29.97 fps. It was filmed in australia, so i’m was thinking 25 fps. I did Qtgmc bob + srestore omode 6, like my previous tv show. And it got rid of maybe 99% combing, but every few seconds or so, there is like a like a stutter. So then i tried deteelcine from 29.97 to 23.976, i’m able to get rid of most of the combing as well, but there are a few areas like in long john silvers face With auick movements that remained.
I think i am missing something. Footage is pretty bad, believe it comes from a poorly encoded dvd of an unremastered Film. My plan was to get it in the best progressive possible and then run it thru topaz video enhancer ai bring it up to 4k or 8k, maybe do further color correcting in resolve, maybe add back in some film grain, and then downscale it via spline to 720p or 1080p.
So a person on videohelp looked at it and said:
That video is basically telecined film. But interlaced frames were encoded progressive so the chroma of the two fields was blended together. The basic fix is TFM().TDecimate() to get back to the original film frames at 23.976 fps.
After that you'll see the blended chroma as horizontal color stripes when colored objects are moving. There might be a way of using the chroma of the previous or next field/frame when the stripes are detected but the easiest thing to do is blur away the choroma stripes, MergeChroma(last, last.Blur(0.0, 1.0).Sharpen(0.0, 0.7). But some ghosting of the colors will remain.
Beyond that there are occasional dropped and duplicate frames. There's not much you can do for that except manually insert of remove frames. Not worth the trouble in my opinion.
So thats why i asked. I dont need to do It the way He suggested. I’m open to better options.
On a side note when i use VIVTC to detelecine
I want to capture the most combing, so despite hybrid saying the sweet spot is 32/32 or 16/16 it offers a smaller box to find more areas of smaller combing during movement.
There is a bug on legacy hybrid 2018 that when i drop block x/y below 16 on the x-axis like 8, 4,2 it crashes.
