 Newer versions of mpv now ship with debanding capabilities, so no additional configuration is required. You can enable debanding anytime during playback by pressing `b` (default keybind).
 
+For sources where the default debanding isn't effective enough, you can apply more aggressive debanding profiles such as:

+```properties
+[BrazzersDeband]
+deband=yes

+Keep in mind that stronger settings will cause a loss of detail and should be reserved for situations where the loss of detail is acceptable for reducing banding.

 ### Scaling
 
 Scaling is the process of taking content that does not match your screen resolution and resizing it to fit your display. *See the [Playback Guide](/guides/playback/#scaling) for more information.*
