smpte 2094 - wistar - 11.01.2019
I wonder if the new standard of SMPTE (smpte 2094) will be added to hybrids in the future.
Smpte 2094 is known as HDR 10+ in the display industry.
Looking forward to your reply.
RE: smpte 2094 - Selur - 11.01.2019
x265 has two direct to HDR10+ related options:
--dhdr10-info <filename>and
--dhdr10-opt, --no-dhdr10-optwhich Hybrid supports through:
"x265->Signaling->HDR-10->Add"
and
"x265->Signaling->HDR-10->optimize"
So to my knowledge Hybrid already supports HDR-10+ as far as it can atm.
If you know of a way Hybrid could improve the support for HDR-10+ I'm happy to listen to any possible improvement.

https：/x265.readthedocs.io/en/default/cli.html#cmdOptions-dhdr10-opt--dhdr10-opt, --no-dhdr10-opt
混合动力通过下列方式提供支助：
“x 265->信号->HDR-10->加”
和
“x 265->信号->HDR-10->优化”
因此，据我所知，混合已经支持HDR-10+，因为它可以自动取款机。
如果你知道一种方式，混合可以改善对HDR-10+的支持，我很高兴听到任何可能的改进。

Thank you for your answer.
I'm surprised that hybrids support HDR 10+,but I don't know how to set up hybrids to get HDR 10 + format when I output video.Can you give me a simple step?
I sent you an attachment explaining SMPTE 2094.
I think it's similar to SMPTE 2084.
thank

--dhdr10-info is a production tool for hdr10plus.
--dhdr10-opt is the hdr10plus verification tool.
I would like to ask you for your comments on what I have suggested.
RE: smpte 2094 - Selur - 14.01.2019
Quote:I would like to ask you for your comments on what I have suggested.I already linked to the description of the options:
--dhdr10-info <filename>Quote:Inserts tone mapping information as an SEI message. It takes as input, the path to the JSON file containing the Creative Intent Metadata to be encoded as Dynamic Tone Mapping into the bitstream.source: https://x265.readthedocs.io/en/default/cli.html#cmdoption-dhdr10-info
Click here for the syntax of the metadata file. A sample JSON file is available in the downloads page
and
--dhdr10-opt, --no-dhdr10-optQuote:Limits the frames for which tone mapping information is inserted as SEI message. Inserts SEI only for IDR frames and for frames where tone mapping information has changed.source: https://x265.readthedocs.io/en/default/cli.html#cmdoption-dhdr10-opt
So with the first option you add your meta data and with the second once you tell x265 to minimize the overhead through that meta data.
Not sure how I could help more.

Hi Selur
I set up Hybrid to output several times according to the suggestion you gave me, and the output was destroyed. Specific settings I added screenshots to the email attachment. Hope to help me solve this problem.

RE: smpte 2094 - Selur - 16.01.2019
You are using a Hybrid version from '2017.10.05.1', x265 didn't support HDR-10+ back then, so I'm not surprised that Hybrid will crash when you add custom options which aren't supported by either Hybrid or x265 at that point in time.
Just looking at the shortened changelog of x265 stable releases over at https://x265.readthedocs.io/en/default/releasenotes.html, shows the last HDR-10+ related changed were in version 2.9 with release date 05/10/2018, which is a year later than the version you used!
As a side note: read the sticky on what data to provide when reporting problems/bugs.

仅看一下https：/x265.readthedocs.io/en/defaul/Relasenotes.html上的x 265稳定版本的缩短更改量，就会发现最后一次与HDR-10+相关的更改是在版本2.9中，发布日期为05/10/2018，比您使用的版本晚了一年！
顺便提一句：在报告问题/bug时，请阅读有关提供哪些数据的粘性信息。

I'm sorry, I didn't see the version information clearly. The screenshot in the attachment below is set to output with the latest version of hybrids, but the result is the same. I don't know if there is a problem with my settings.
