我现在都用mpcvr了，我没那么敏感，算法不静态AB根本看不出来。mpcvr对hdr支持很傻瓜，也省资源。

感覺效果不一樣，應該是杜比比較接近原始意圖吧。看看madvr往後要怎麼修正
...
懒人包没开 gpu-next，两个结果都不关杜比的事

madvr还是等饱和度问题修复后再说吧。

还有一组对比图，MPV播放器截图
MPC-BE使用MadVR截图
首先告诉你你MPV的亮度过高，建议你换个亮度场景看一下你就会发现问题了。

实际上上面两张图都是错的，别看到画面看上去更亮就觉得是正确的。
而且这部哪里来的杜比世界版本就是一个普通的HDR10而已

Q. Does Envy support Dolby Vision (DV) or HDR10+?
A. DV and HDR10+ consist of a HDR10 base stream with additional scene-by-scene metadata. This added metadata allows a DV or HDR10+ compatible display, that is not using a madVR Envy, to at least have some form of dynamic tone mapping for each scene. With the Envy, there is no need or interest in this metadata. This is because the Envy uses the HDR10 base stream (that is part of each DV or HDR10+ stream) to measure every pixel of every video frame in real time. By doing this, the Envy replaces the DV or HDR10+ metadata with our own dynamically generated metadata, which yields superior results than what DV and HDR10+ produce. As an example, the Envy's proprietary approach actually allows the Envy to dynamically adjust its tone mapping not only scene-by-scene, but even within each scene, going beyond what DV and HDR10+ does.
In summary, while from a marketing perspective some people might fear they are missing out without HDR10+ or DV, with the Envy they are already getting what many believe to be the best-in-class tone mapping, without relying on HDR10+ or DV metadata.

你应该使用use TM CUREVE来调整映射保证整个画面的细节，然后通过FALL highlight 跟detail threshold来增加局部的亮度。
想要亮度建议试试这个

以下一组对比图，这也是为什么一直在强调不要为了亮度而亮度的原因
MPV（hdr toys）tone mapping:dynamic综合起来就这个最好。

同样的设置下

第二组对比图你会发现MPV没有什么问题，这就是为什么一直强调一定要测试不同亮度场景下的表现的原因。如果按照你的亮度表现第一组图这块只会更糟糕。
新版本200似乎解決過飽和的問題了
