About video settings
Exposure zones - This settings determines which part of the image is used to calculate the exposure. For most situations, the Auto
setting can be used. For particular requirement, select Defined and then click Edit and select one of the predefined areas.
Gain - Gain is the amount of amplification applied to an image signal. More gain means more contrast and more details but also
more noise. The max gain value is set for all scenes, but affects primarily low contrast scenes controlling the amount of allowed noise
in the image, which in turn also limits the contrast.
