实际上很多人误以为HDR的片子亮度对比SDR会高很多，但实际上并不是。实际上HDR片子平均亮度对比SDR的片子来说降低很多。HDR只是在该亮度的情况下对比SDR来说会亮很多但整体的画面平均亮度对比SDR是降低的。再加上tone mapping对于画面亮度的影响比起SDR时代GAMMA 影响大很多。
还有就是你这视频明显能看出静态映射的局限性。
Youtube 所有的 HDR 视频元信息都会被覆盖为 1000nit，也没有杜比视界。而且 Spears & Munsil Montage (2019) 的调色很烂。不如去B站看 Linksphotograph， 还有真杜比。
这个马的场景我的评价是
那么为啥有三个电视机的棕马变成了黑马？
相机动态范围不足

昨天照你說測試mars後,發現真的影響滿大的,不過shadow recovery開到最強好像比較接近sdr意圖
左邊mars10右邊mars20
shadow recovery:上面ow下面insance

Spears & Munsil Montage 已经发布2023新版本了
不过我不知道youtube上这个片源表现怎么样，但是原盘这个是没有任何问题的，而且提供不同版本

你不能拿HDR转SDR跟原生SDR作为参考去调教的
两者是完全不同的两个概念，前者是亮度坐标系转换下的SDR，后者是蓝关标准下的SDR。千万别去接近SDR效果来调整优化你的HDR设置参数。
英伟达驱动就不支持杜比视界 悲！{:5_185:}
话说有没有文章介绍HDR页面里的各种选项代表什么含义有什么功能作用啊……我似乎没找到有相关教程，想自己调整也无从下手啊……

很抱歉没有
Hi there,
I haven't looked at MPV in a while, but some people I trust recently
compared and said that madVR is still on top (for now), although MPV
seems to be getting close. Do you have a different opinion?
I haven't looked into Dolby Vision yet because my main focus is on the
Envy hardware product atm, and I don't think we can implement support
for Dolby Vision in our hardware device without having a license.
Maybe we will get a license at some point, but even if we do, I'm not
even sure if our hardware device will see the RPU layer/metadata
directly. The Envy receives signals via HDMI, and I think those
signals are already "transformed" into something else by the Dolby
Vision compatible player. Though I'm not 100% sure about how it all
works exactly. In any case, I may look at RPU at some point in the
future, but it doesn't have a high priority at the moment.
Your report about "histogram-based dynamic mapping in MPV" sounds like
you think that MPV looks better than madVR now? That doesn't match
what I've heard from other people. Do you have some links that talk
about what MPV does exactly? Maybe some screenshots that show how MPV
looks better than madVR?
Best regards, Mathias/madshi.
