我一直以为动态映射对每一帧进行处理

动态映射是可以做到每一帧处理但是完全没必要
还有无论HDR10还是DV都是基于PQ的，PQ是绝对亮度，该是什么亮度就是什么亮度，超过显示设备峰值亮度就进行压缩，在显示设备亮度范围内就按照实际亮度显示（对于动态映射）
而静态映射在于静态映射在一部片子只使用一条映射曲线，但问题是一条映射曲线跟本无法应付不同亮度场景，具体的区别看我上面101楼的对比图

动态映射是可以做到每一帧处理但是完全没必要
我仔细看了101楼的图，确实如你所说：
在 “HGIG+动态映射” 的前提下，低于设备峰值亮度的信息会按照1：1的绝对亮度呈现
而高于的亮度信息会采用动态映射进行重新映射以确保画面的正常和舒适
但是按照目前的结论来看，“杜比视界”是无法被“HDR10+动态映射”取代的，尤其是显示设备自身拥有超过1000nits的峰值亮度时
但是我还是有一点不确定，动态映射真的只有一种吗？不存在把低亮度信息根据显示设备的实际情况往高了拉的情况吗？
根据我的经验，我看到别人在使用LG G系列电视时，G3和G4（10APL峰值超过1000nits），用电视内置的动态映射，那个画面确实是被提亮处理了的（但是并不会整体提亮，因为该暗的地方还是很暗）
当然，我这么问不严谨，因为前提说的是madVR的动态映射

我早就做过无数次的尝试了，也编写过超过十几条的profile，各种动态色调映射方案同HDR passthrough进行瞬间切换对比，madVR的动态色调映射+HDR输出是必定会压缩亮度的，否则我怎么会让hsmms“大神”提供我上面的HDR600的实战证据呢，连300nit都保不住哦！
只有一种情况下，madVR的动态色调映射+HDR输出是好于HDR passthrough的，那就是真正超高亮度制作的影视，目前我只在“海王”和“巨齿鲨”上看到过，这是杜比视界和madVR的动态色调映射明显好过passthough，当然还有些私人草根制作的高亮HDR演示片。
如果你仔细看过我主楼的所有文字和图，你就应该明白，我不是说杜比视界或动态色调映射不好，而是现在的片源情况根本不需要，因为超高峰值亮度的内容往往只占画面的极小部分或是只有极少帧上会有，帧平均亮度20nit都没有哦！假定全片一直有几个像素的峰值亮度是10000nit，而其余绝大多数像素内容的亮度都在100nit以下，你希望看到这几个像素的高光细节而损失掉全片画面的亮度吗？杜比视界和动态色调映射就是做这个的哦！我说的夸张点，否则你不能理解的哦！

我的建议你还是把你这些东西 全部抛掉，先不要把问题想那么复杂。
你只要记住以下几点
1.PQ是绝对亮度，HDR10/DV都是基于PQ的，在设备亮度范围内就按照实际亮度显示，超过就 进行压缩。
2.静态映射是一部片子只使用一条映射曲线，而动态映射是针对不同亮度场景使用不同映射曲线。
3.制作标准亮度是制作标准亮度，不要认为这是这部片子的峰值亮度，就比如HDR10制作标准亮度是1000nit，但不代表你这部片子的实际峰值亮度有1000nit，也有可能整部片子最高亮度就200nit。

动态映射技术原理上都是一样的，但不代表都是一样的，也有好坏的区别
至于LG的动态映射那玩意就是垃圾，建议不要使用，使用后严重偏离标准PQ曲线。

至于你觉得画面更亮只是你感知上觉得更亮，但实际亮度有可能并没有提高甚至被压缩了。

因为同样我还看了一部HDR10的片子（《阿凡达2》的原盘），在手机上，以肉眼目测，峰值并没有超过1000nits
换句话说，如果动态映射不能真的提亮，那么杜比视界还是无可替代的

我本来以为可以通过 HGIG+动态映射 把HDR10干到2000nits峰值，然后在雷鸟U8（峰值2000nits）这种显示器上会有不错的表现
如果按照目前的结论，即使是madVR，使用HDR10片源，依然是峰值只有1000nits，等于这种2000nits峰值的显示器在看片的时候完全是无用的……

苹果手机的HDR播放是可以随时改变亮度的，你手往上一滑，低亮度的HDR视频确实能拉亮，但电视机没有这个骚操作，至少我没看到过，PS: 通常HDR电视机在播放HDR时是自动把所有亮度拉到最高，而杜比视界则会更进一步，把对比度也拉到最高，也就是说你在电视机播放HDR视频时已经无法拉高任何亮度设置了，已经都是最高状态了！
HDR的亮度是绝对亮度，我写过一个科普贴，你有空看看吧：https://www.chiphell.com/thread-2588913-1-1.html

显示设备的硬件能力是固定的，怎么可能让你看到超过其能力的亮度，而杜比视界的色调映射方式是降低画面的整个亮度以便让你看清超过显示设备硬件能力的高光细节，这个解释你看明白了吗？
但凡真实对比过杜比视界和普通HDR播放的人，都会知道：普通HDR播放的整体画面亮度观感要强于杜比视界，因为普通HDR播放基本就是做高光剪切的操作，当然LG oled电视机的早期色调映射算法也是做类似于杜比视界的亮度滚降方式，所以才会被人所诟病！

HDR10和杜比视界只是“制作基准”不一样
但是杜比视界本身就多了动态映射以适应设备，而HDR10本身不带动态映射
所以如果HDR10+动态映射，就跟杜比视界没有任何后续上的区别，区别就只是片源所框定的“亮度信息本身”
而片源所框定的“亮度信息”，没有所谓的HDR10和杜比视界谁更亮或者谁更暗，只取决于片源本身
所以确实可以说杜比视界（单层）和HDR10相比，主要的区别，仅是多内置了一套动态映射
不好意思[傻笑]

你想表达的意思我明白，以硬裁切牺牲掉部分高亮细节的方式（画面占比极少），从而保住整体的峰值亮度，这更符合大多数片源的实际情况，因此动态映射实际意义不大
主要是我一开始理解的动态映射就是错的：
我以为它会额外的让亮的更亮，暗的更暗，从而压榨显示设备性能并增强HDR（对比度）效果
并且这一切的前提是一个画面中各细节的亮度比例关系不变
而且这种映射方式针对每一帧进行处理[傻笑]
也就是如果某一帧的峰值是300nits，最暗细节是0.001nits，然后有一些中间细节是10nits
那么动态映射会让300nits以600nits呈现，最暗细节以0.0005nits呈现，然后中间细节依旧在10nits附近（按照各自比例进行拉伸）[傻笑]
但是真实的动态映射实际就只是针对某些帧，当它们的最大亮度超过显示设备最大亮度时，做一个滚降处理……从而保住细节，但降低整体亮度
当这些帧结束，再返回到标准PQ（如果显示设备支持其亮度范围）
而hsmms的意思，我现在也明白了，其表达的核心：
因为大多数显示设备的内置PQ过于辣鸡，所以需要HGIG+动态映射，从而使得映射变得更加正确
也就是说你的测试结果有一个前提那就是仅限于你的设备（包含了内置PQ的水平），在这个前提下HDR passthrough更加符合你的口味
如果是我的口味：我会想尽办法在保持比例的前提下增强对比度，我才不要什么原汁原味呢，HDR就必须是对比度！[偷笑]

动态映射跟普通映射（静态映射）最大区别是动态映射一部片子根据不同亮度场景使用吧不同的映射曲线，而普通映射只在一部片子中使用一条映射曲线。普通映射你要么hard clip处理要么就是roll off处理，这会导致一个问题如果你hard clip处理你画面的整体亮度是保留了，但是细节会丢失，使用roll off处理细节保留了但亮度会丢失。而动态映射正好解决了这问题，说简单点就是需要保留亮度场景我可以使用hard clip处理，需要保留细节的场景我可以使用roll off处理，因为动态映射可以在不同亮度场景下使用不同的映射曲线。
HDR10（静态映射）记录的是绝对亮度，也就是基于标准显示设备的亮度信息。这会导致一个问题就是：只有当消费者的观看环境与设备跟碟片制作方完全相同时，绝对亮度信息才能还原创作意图，这个条件十分苛刻。
具体多难你看下面的例子就会明白，下面的设备峰值亮度全部超过1000nit，但实际亮度表现呢？中间参考的是索尼的HX3110
还有HDR是绝对亮度，300nit内容只会300nit亮度去显示，无论你 普通映射还是动态映射都不会让300nits以600nits呈现
不存在动态映射实际就只是针对某些帧这种东西，要么一部片子使用普通映射要么就是动态映射，也不存在再返回标准PQ的说法跟本不存在这个步骤。
使用HGIG目的是避免二次映射问题，还有不是PQ垃圾是映射算法垃圾。PQ是感知量化，使用色调映射尽可能贴合标准PQ，但现实是你很难做到这一点，所以才需要动态映射。

但是你之前说过madVR可以按自己口味调映射，然后我又看到这么多参数，想先研究研究
但是如果不能提亮，感觉研究的意义就不太大了，我的想法就是拉高对比度，不需要原汁原味[傻笑]
