Automatic Gain Control (AGC) Limit
When recording in dark surroundings, the camcorder will automatically
Increase the gain to try to get a brighter picture. However, using higher
gain values may result in more noticeable video noise. You can select
the AGC limit to curb the amount of noise by setting the maximum gain
value to be used. The smaller the AGC limit, the picture will be darker
but will have less the noise.
