Best way to resize?

[Selur]

Ok I want to encode with x264 and I can only pick lossless with profile high4:4:4 and none.

That is correct, see: https://en.wikipedia.org/wiki/Advanced_V...r_profiles
Ah sorry, just checked and I removed the 0, but enabling lossless is enough, command line will include '-qp 0'.

As for denoising and sharpening I don't want to denoise I want all the grain to remain and as for sharpening I tried aWarpSharp2 and it looks really good, I just want to make sure that I can use sharpening without it creating artifacts or losing details. As far as I can tell aWS doesn't do that though and it reduces those dark shadows around the lines which I think are there due to the low resolution.

Then simply don't use stepped resize and sharpening.
Any filtering will cause some sort of change that could be understood as artifact.

Going to bed now, but your best choice is probably to look at the resizers and use the one that best fits to what you want.
