Hi everyone.
When downscaling UHD->FHD (projector FHD) on test patterns S&M (Chroma Multiburst and Chroma Zone Plate), the Lanczos (tape 4) chroma upscaling looks much better than everyone else (with the exception of NGU AA, I just don't have enough power for it). super-xbr: the test circle looks awful because of the moire throughout the area. Jinc - too very dark edges in the corners. Spline looks a bit darker around the edges than Lanczos. Bilateral is generally terrible. Lanczos visually very similar to NGU AA on all test patterns. I use the SSIM 1D + LL + AR + AB downscaling algorithm.
How to choose the right algorithm? According to test patterns, as I did, I chose the closest to NGU (Lanczos for me), which looks great. Or put the most powerful (super-xbr) and not look at the test patterns?
