ALC level
Adjust the video output level (-15 to 0 to +15).
Select the range within which the ALC will operate. A positive
value is more useful for low-light conditions; a negative value is
more useful for very bright conditions.
Some ALC adjustment may improve scene content when Smart/
BLC is enabled.
Peak average

(-15 to 0 to +15). At -15 the camera controls the average video
level, at +15 the camera controls the peak video level.
