Trying the chroma offsets is also a great idea, at least for those scenes. So glad to have —zones! |

I'm giving up... crqpoffs and its brother also didn't work wonders. The bitrate went up... but even at the maximum of -12 it still didn't reach a detail retention level I liked.
And aq-mode 3 didn't work out for me as well... I went as far as setting aq-strength from 1 to 5, ultimately with a crf of 33 (~6000kbps) but... no. If someone is out for a challenge... grab Aladdin and try to bring it down to a 5000kbps encoding without totally smeared red backgrounds. You'll start to hate the ladies at the window at 0:07:19 - 00:07:24. Personally I'll go on with zones... It'll take hours but it will work in the end. |

Ah. I suggest slower as the fastest preset that really starts exercising HEVC’s more unique features. I might throw in --tskip to see if that might help this weird case. It can sometimes help with sharp and weird edges.
Also, if you have a target file size and are comparing different encoder settings, you really should be using 2-pass VBR. It’s really hard to compare features when both output AND file size is changing. Lastly, Are we sure that negative values reduce chroma QP? I had it in my head it was the other way around. But I rarely use that feature. |

Ok... give up on Dolby Vision encoding now. Question is. How to encode my first HDR10+ bluray with x265 to preserve HDR10+? Can HDR10+ be played from MKV? Or must be m2ts?

@jlpsvk: What do you use for playback on a pc? (For reencoding HDR-10+ data: 1. extract meta data using hdr10plus_parser 2. reencode with x265 while specifying the extracted data 3. multiplex to the container of your choice)

Do you have an HDR10+ compatible TV too?

x265 v3.0_RC+14-46b84ff665fd (32 & 64-bit 8/10/12bit Multilib Windows Binaries) (32bit : GCC 7.4.0 / 64bit : GCC 8.2.1)
Code:
https://bitbucket.org/multicoreware/x265/commits/branch/default Checked with Pradeep (@MulticoreWare) about why the Default Branch haven't been pushed to v3.0 'Stable' and this is the reply/info i got " Our plan is to continue to use 3.0_RC on the default branch and have completed tags only on the stable branch. So we don't intend to merge back. " |

than violet-blue (<<500nm). Red has always been a mess in encoding, especially when encoding in yuv420 where chroma is subsampled and red pictures appear in their glorious blockiness. There's still a lot of work to be done to optimize encoders to accomodate for perception: we should improve quantization both in dark picture and red-dominant picture, but this depends also on the viewing conditions (i.e. not so important in small mobile screens) Not to mention higher order of complexity optimizations like saliency based optimizations or similar. I have developed many times models that change params using zones-like params to improve the performance of a given encoder. This is one of those cases.

Version 3.0
=========== Release date - 23/01/2019 New features ------------- 1. option:: '--dolby-vision-profile <integer|float>' generates bitstreams confirming to the specified Dolby Vision profile. Currently profile 5, profile 8.1 and profile 8.2 enabled, Default 0 (disabled) 2. option:: '--dolby-vision-rpu' File containing Dolby Vision RPU metadata. If given, x265's Dolby Vision metadata parser will fill the RPU field of input pictures with the metadata read from the file. The library will interleave access units with RPUs in the bitstream. Default NULL (disabled). 3. option:: '--zonefile <filename>' specifies a text file which contains the boundaries of the zones where each of zones are configurable. 4. option:: '--qp-adaptation-range' Delta-QP range by QP adaptation based on a psycho-visual model. Default 1.0. 5. option:: '--refine-ctu-distortion <0/1>' store/normalize ctu distortion in analysis-save/load. Default 0. 6. Experimental feature option:: '--hevc-aq' enables adaptive quantization It scales the quantization step size according to the spatial activity of one coding unit relative to frame average spatial activity. This AQ method utilizes the minimum variance of sub-unit in each coding unit to represent the coding unit’s spatial complexity. Encoder enhancements -------------------- 1. Preset: change param defaults for veryslow and slower preset. Replace slower preset with defaults used in veryslow preset and change param defaults in veryslow preset as per experimental results. 2. AQ: change default AQ mode to auto-variance 3. Cutree offset reuse: restricted to analysis reuse-level 10 for analysis-save -> analysis-load 4. Tune: introduce --tune animation option which improves encode quality for animated content 5. Reuse CU depth for B frame and allow I, P frame to follow x265 depth decision Bug fixes --------- 1. RC: fix rowStat computation in const-vbv 2. Dynamic-refine: fix memory reset size. 3. Fix Issue #442: linking issue on non x86 platform 4. Encoder: Do not include CLL SEI message if empty 5. Fix issue #441 build error in VMAF lib |

@LigH: Why? Last code change was from 2019-01-25,... 3.0 release was out there since 2019-01-23 -> https://bitbucket.org/multicoreware/...f10364bb232c2c
