I recall some recent codec or project that addressed anime compression, something similar to the following:

• Av1an

  65 1,356 7.5 Rust

  Cross-platform command-line AV1 / VP9 / HEVC / H264 encoding framework with per scene quality encoding

>The more threads you add into a pool, the more encode overhead you will experience, since every row of encode requires the upper right CTU block to complete before it can proceed.

Nowadays, we don't have to worry about that, since we can use scene-based encoding instead. [1][2] In addition to allowing for full use of all cores, without any loss of encoding or processing efficiency, different encoding settings may be chosen for each scene, increasing potential efficiency.

• vmaf

  41 4,214 8.8 Python

  Perceptual video quality assessment based on multi-method fusion.

  

And the issue with that is that they're using PSNR and SSIM as quality metrics, which are useful for images, but haven't been designed for video, so they cannot take into account temporal factors and how motion masks distortion, etc.

I think for AV1 they're using VMAF too, which is an actual video quality metric (https://github.com/Netflix/vmaf).
