basiccly it has a problem that Madvr can fix when its happends in 480p video (jagged zig zag lines) but on 1080p sample there is no more to go up (in terms of upscale)

anu avisyth script to try and fix it? (can use this images for testing)

you can see it very clearlly on the fork and knife at the second pic

Your video is poorly upscaled standard definition, not true high definition. So those jaggies are part of the picture. To reduce them you need to downscale back to SD, then upscale properly. Something along the lines of:

BilinearResize(800,576) # play with different sizes to get the sharpest picture with the least artifacts
# maybe add an atialias filter here, like Santiag()
nnedi3_rpow2(4, cshift="Spline36Resize", fwidth=1920, fheight=1080)
aWarpSharp(depth=15)
Sharpen(0.3)

Of course, if you upscaled this yourself, go back to the original source rather than starting with the badly upscaled video.
