4.8 Video preferences
The means used to control the camera depends on your work methods. A remote OCP
can be used and a low user level can be selected to restrict the available camera
functions. Alternatively, video functions can be controlled on the camera itself. The
following functions are available on the camera:
• Standard settings
• Test signal
• Gain selection
• Optical filter selection
• Colour temperature
• Auto-white balance
• Exposure time
• Black stretch
• Auto skin contour
Many other video functions such as contour, black, gain, knee, gamma, matrix and
white limit functions are available in the
VIDEO menu.
4.8.1 Standard settings
To ensure that some of the camera functions are not set to unusual values, a standard
file has been defined that contains the default values for most video functions. The
table in the Appendix lists the values that are set when the standard file is recalled.
To recall the standard values for the various video functions, press the green STD
button (6) on the left-front side of the camera and hold it for two seconds. The
standard values only take effect when the camera is not on-air.
The standard file can be selected as either a factory or a customer standard file.
Changing the standard file can only be done in the System security menu if the owner
card or the PIN code is used.
The Non-standard indicator (33) lights when the video settings are not set to their
standard value, for example, when exposure is not set to nominal. It also lights when
black stretch or extended iris is on and if AWC or FL is selected with the colour
temperature selector.
4.8.2 Test signal
The left-front side panel of the camera has a Colour bar switch (9) for switching on a
colour bar test signal. The colour bar is the standard test signal that is used to set up
and check the camera before use.
