How to make a video lighter or darker

How to make a video lighter or darker?

There are several ways:

1. You can change the brightness and contrast of the video in the video driver settings. This will work for many video players and many types of video. But once you change it, users often forget about it. We do not recommend this method.
2. You can change the brightness and contrast of the video in the video player settings. You can also set up hotkeys for these actions.
3. For HDR video, you can adjust the gamma using the "SDR display nits" setting in the MPC Video Renderer settings.
4. You can write a pixel shader and add it to the "Post-resize pixel shaders". As an example, see the Gamma shader.
