Adjusting the White Balance and Black Balance
To record high-quality video with the AG-HPX370P/AG-
HPX371E, the black and white balances must be adjusted 
according to conditions.
For higher quality, it is recommended that the adjustments 
should be made in this order AWB (white balance 
adjustment)  ABB (black balance adjustment)  AWB 
(white balance adjustment).
 NOTE
If white balance and black balance adjustments are made 
while the video image is distorted due to GENLOCK, the 
adjustments may not be correct. Wait for the video image 
to return to normal before performing white balance and 
black balance adjustments again.
