Set-up and operation HD video mode 5-11
V-SHIFT
The vertical shift switch (V-SHIFT) at the front of the camera is used
for displays with the same frame frequency as the camera, for
example TV sets. It is an up/down type switch. Pressing the switch
moves the black bar up or down so that it is no longer visible in the
viewfinder. This function is only active when the camera is not
genlocked and when it is not on-air.
If the frame frequencies of camera and monitor are different use the
clean scan function.
CRT Exposure
A third possibility can arise when shooting a monitor whose
synchronization is locked to the camera's. Stripes might be visible
in the picture of the monitor. (This is more usual with 16:9 cameras.)
To remove these disturbing line pairing effects between monitor
and camera lines, select the CRT option with the Exposure time
switch.
