You already have pretty much "the" settings for anime encoding.
Also avoid the "animation" preset for anime, if you thought about it.
Here an excerpt from kokomins:
TL;DR Summary for x265 Encode Settings
Set preset=slow. Then choose 1 following to override the default parameters. These are my recommended settings, feel free to tune them.
- 1 Setting to rule them all: crf=19-20, Code:
- Flat, slow anime (slice of life, everything is well lit): crf=19-20, Code:
- Some dark scene, some battle scene (shonen, historical, etc.): crf=18-19 (motion + fancy FX), Code:
- Movie-tier dark scene, complex grain/detail: Movie-tier dark scene, complex grain/detail: crf=16-18, Code:
- I have infinite storage, a supercomputer, and I want details: preset=veryslow, crf=14, Code:
Here an excerpt from a Reddit poster:
- Use the 10-bit encoder. Not the 8-bit nor the 12-bit.
- Optimally, use the slow preset. Veryslow preset is a luxury reserved for very powerful systems and high crf (22+) encodes.
- aq-mode=3! This sets dark scene aq bias, which is really helpful for anime, as this is where most of the artifacts and banding will be.
- Don't use tune animation. The appended options are: psy-rd=0.4:aq-strength=0.4:deblock=1,1:bframes=(preset+2). These are optimized for cartoon-style animation, anything more complex than slice of life is going to suffer, especially with newer BD releases utilizing dynamic grain to prevent banding. For "Anime" anime, I recommend psy-rd1 to 2 (more complex/action packed/detailed anime = higher value needed, also increases bitrate), aq-strength 0.6 to 1 (more complex/detailed = need higher value, don't go beyond 1 as you may introduce ringing artifacts. You will mostly use 0.8-1. Also raises bitrate.), deblock -1:-1 to 1:1 (depends on source, leave on 0:0 if you don't know what to use) and bframes 4 to 8 (I highly recommend 6, 8 if possible. Encode penalty is only ~5% going from 4 to 8). Additionally, if your source has grain, psy-rdoq should be raised from the default 1 to 3-5 depending on source (note: only combine higher rdoq with crf<18 and no-sao, or you'll end up with grain "blocks" instead of grain "grain").
- Use limit-sao for crf 17-19. Use no-sao for crf<18 if there are fine grain present. Else leave on default.
- Use no-strong-intra-smoothing only for crf<16. This helps preserve fine details. High crf will result in blocking due to lack of smoothing on 32x32 blocks.
- 1 Setting to rule them all: crf=19-20,
