Resizing from 4K to 2K with maximum PQ

[Tenaka]

While using the lossless options I was anticipated a file around the same size as the source one.

I think I'll go with a CRF of 10 and leave the rest at the previous settings described in my message.

About your "PPS" are you talking of resize algorithms ?

I'm going for a sharp image and I'm divided between :

• 9 - lanczos (sharp image but heavy ringing)
  
• 10 - bicubic spline (limited ringing but soft image)
  
• 6 - luma bicubic, chroma bilinear (faster than Lanczos and B-spline)
  

When I watch 4K content with madvr as renderer, I'm using the Mitchell-Netravali (cubic(1/3,1/3)) algorithm for downscaling to 2K.
My CPU is rocketing at 100% on all threads though.
