I did a new video with 3 versions of my last script :

- One that looks more like a "modern progressive image" and is the smoothest.

- One that reminds more the "old CRT feeling" but without the scanlines. Strangly, I find that the scanlines added more relief with the old Super Nintendo games (the signal was progressive with a resolution of 256x224 in low resolution mode) that on a modern display. But it was just a illusion, because as you know, the scanlines are black So the resolution is the same with and without scanlines.
So I got an idea to imitate this illusion, just in reducing the horizontal resolution with the "nearest neighbor filter" (PointResize), because it's almost like doubling the vertical resolution by the same lines of pixels, but without sacrificing the information brought by the upscaled resolution and especially the one from the vertical resolution.
It's like a reverse logic of the illusion of the scanlines Personnally, I find it's not bad ! It really remember me the image, the speed and so the feeling of the original Super Nes video games on a CRT display. But it less smooth than with the 1st script above and a bit less defined because of the half horizontal resolution, but the illusion suggests the contrary to the brain. For an old feeling, I find it's good !

- One that is something in between the old and the modern style, because I used the Nnedi3 filter which is like "`Orum" said, adapted to a interlaced source, even if in this case, the signal is progressive. But the scanlines of the old CRT display with a progressive signal remember me the same feeling than a interlaced signal on a modern display. So for me, it's between these both old and modern feeling
