可惜 mpv 沒辦法判斷播放的是不是動畫，所以就用最通用的 FSRCNNX 吧。
文件名字里加上”Animation“字样，然后profile写代码抓关键字不就好了

如果是转换SDR可以不需要，但是你输出HDR那就是必须的
HDR直通根本不需要！

HDR直通根本不需要！
Specifies the measured peak brightness of the output display, in cd/m^2 (AKA nits). The interpretation of this brightness depends on the configured --target-trc. In all cases, it imposes a limit on the signal values that will be sent to the display. If the source exceeds this brightness level, a tone mapping filter will be inserted. For HLG, it has the additional effect of parametrizing the inverse OOTF, in order to get colorimetrically consistent results with the mastering display. For SDR, or when using an ICC (profile (--icc-profile), setting this to a value above 203 essentially causes the display to be treated as if it were an HDR display in disguise. (See the note below)
When using an SDR transfer function, this is normally not needed, and setting it may lead to very unexpected results. The one time it is useful is if you want to calibrate a HDR display using traditional transfer functions and calibration equipment. In such cases, you can set your HDR display to a high brightness such as 800 cd/m^2, and then calibrate it to a standard curve like gamma2.8. Setting this value to 800 would then instruct mpv to essentially treat it as an HDR display with the given peak. This may be a good alternative in environments where PQ or HLG input to the display is not possible, and makes it possible to use HDR displays with mpv regardless of operating system support for HDMI HDR metadata.
mpv每次打开都是默认最大音量就很烦，还有字幕渲染我也不是很会调，用4k屏看太糊了

那麼你螢幕會設定多亮？找出靜態對比最大的亮度嗎？還是把亮度調到最大？
像我目前顯示器是設定在 158nits，所以我 --target-peak 就設定在 158？

好方法！但還是希望有可以通用一點的方式，所以就都固定 FSRCNNX 了

校色仪测量，测到多少就填多少

不是，我是說你顯示器的亮度設定
你是會找出對比最大的亮度，還是直接調到最亮呢？
像我 40% 亮度的對比是比 50% 或 60% 還要高的，那麼你會選 60% 還是 40%？
如同這張圖表：https://pcmonitors.info/reviews/benq-ew277hdr/#Contrast_and_brightness
