While counter intuitive at first, this is due to the more complex algorithms used to more precisely estimate motion and preserve details. In x265, the slower the preset, the bigger the file size is at the same crf. What preset should I use?įirst, one must understand x265 is fundamentally different than x264. In fact, it is much less supported, and from my tests back in 2018 the 12-bit encoder is actually worse than the 10-bit encoder at high crf likely due to less resources put into developing it. Why not just use 12-bit then you say? Well, to put simply: moving form 8 to 10 bit increases color gradient available from 256 to 1024 to eliminate banding, but going to 4048 in 12-bit really isn’t noticeable. To keep things short and not get into technical details: use the 10-bit encoder (Main 10 profile).ġ0-bit produces slightly smaller files while preventing banding from 8-bit compressions ( this isn’t a joke, quantization and linear algebra is a mysterious thing). Which x265 encoder? 8-bit, 10-bit or 12-bit? Other useful stuff for dealing with Anime (research them yourself):

Guides on how to do this are easily found. (Update: 1.4.0 is still under development but should be updated to use a proper 10-bit pipeline for HDR.) If you want FDK-AAC, you will need a custom compiled version. Hopefully 10-bit pipeline will be supported once HDR becomes common. While it runs on an 8-bit pipeline, this isn’t an issue for Anime. It allows reading Blu-ray disks (unencrypted), and has a pretty UI to deal with. AV1 began major development in mid-2018 so by that logic we got 2-3 more years to go. HEVC took 3-4 years before it was more widely accepted by Anime encoders, and took 5 years until 2018 before I began experimenting with it.
For now, they look promising, and I am excited to see results in a few years. It performs (quality-wise) not as well as libaom, but quality is still better than x265 (SSIM), and encode times are much more reasonable. SVT-AV1 is Intel and Netflix’s scalable implementation. Unfortunately the reference encoder libaom is still in early stages of development and is rather inefficient. IIRC some of its baseline is based on VP10, which Google scrapped and had its codebase donated to develop AV1.

AV1 is a next gen codec with members from many tech giants (Apple, Google, MS, etc.) to create a royalty free codec. Update: Apple now somewhat supports VP9 on some devices for 4K streaming (iOS 14+). VP9 today is mainly used by Google (YouTube) via the webm/DASH format, which Apple refuses to support on iOS devices which is probably why it’s not widespread. HEVC does have a slight advantage in terms of parallel encoding efficiency, though they are both just as slow when encoding compared to x264. HEVC is about the same quality as VP9, a codec by Google. In terms of efficiency as of right now (2019/2020), when properly encoded, HEVC could save ~25% bandwidth minimum compared to AVC (H.264, with its encoder known as x264) from my observations.

Most modern devices support hardware decoding (iOS, Android, laptops, Macs, etc.), and even at 1080p most older consumer PCs should be able to software decode just fine. Despite these downfalls, HEVC does compress much better in higher crf (lower bitrate) and has been a good codec to use since 2018. While most devices now support HEVC in some form or another, adoption didn’t really kick off. While developed as a replacement for H.264, due to early performance and licensing issues, it didn’t gain much traction, especially as a streaming format. X265 is a library for encoding video into High Efficiency Video Coding (HEVC / H.265) video compression format.
