Chapter 9: Brightness-Contrast-Saturation
The MediaSonic HD Player provides some built in control over the video output. The control is global and applies
to every file and all of the different outputs – including the HDSDI digital output.
The output controls are available from the Channel Properties dialog box
•
Right click over the Playlist and select Channel Properties from the drop down menu. From the Channel
properties dialog,
•
Click over the BCS button. This will produce the adjustment dialog shown here.
Separate control is provided for the Brightness, Contrast and Saturation. The illustration above shows the default
settings, which provide no correction of the output signal.
To change a BCS setting:
Click over the rectangular bar for the required option and drag it to the left or right. Any changes to the settings
will take effect immediately on the various video outputs.
The adjustments are as follows.
Brightness
Brightness affects the intensity of the video level. Dragging the bar to the left causes the brightness to decrease –
i.e. the picture gets darker. Dragging the bar to the right causes the brightness to increase – i.e. the picture gets
lighter.
The range is 0 – 255 with 128 being the default setting.
Contrast
Contrast refers to how far the “whitest whites” are from the “blackest blacks” in a video signal. A picture with
high contrast appears very stark. A picture with low contrast is often referred to as washed out (there is not much
differentiation between black and white and the picture appears dull).
Dragging the bar to the left decreases the contrast (reduces the distance between black and white). Dragging the
bar to the right increases the contrast.
The range is 0 – 255 with 128 being the default setting.
