Hello. Thanks for your answer !

Bilinear, it's a bit too sweet.

I tried with Nnedi3 too. But with this filter in first position, we have some deformations of straight lignes.

BicubicResize(b=0, c=0.5, 1408, 1080)

I noticed, when we begin with a filter like Bicubic or Spline16, we haven't this problem.

I know, I'm too perfectionist

But it's not only for Super Nes videos. I want to use this for others low resolution videos later.

I search for a natural renderer. But not too sweet (and not too sharp). It's why I want to upscale my videos

For the transparency of the enlargement, I exactly find that it's not so bad with the upscaling of Intel HD chipset. But I don't know where I can find a similar thing.
