Analog Composite Video Input
Profile Family 35
Status Indicators
These indicators show the current status of the analog composite video input:
VITC Present, Input Locked, and Auto Timed. A green light indicates that a
status is on. These are indicators and cannot be edited.
Video Standard
You have two choices for the video standard of this input board: NTSC with
pedestal or NTSC without pedestal. If you change the standard, restart all tools
that use this channel. The board can serve both standards, but the input can only
accept one at a time.
Renaming the Input Signal
Enter a new name for the input signal in the Name box. For example, if the
signal is a network feed, you could rename it to Network_Feed. The VITC
name, the window title bar, and the configuration tree name change
automatically as you enter the new name. Names can be up to 30 characters, and
can include spaces. To return a renamed signal to the default, delete all the
characters in the text field, and press Enter.
VITC Reader Setting
If you use Automatic VITC detect, the Profile system uses the range set in the
From and To lines to look for the VITC signals. If Automatic VITC detect is
not checked, the system expects to find the VITC signals on the VITC Reader
Line 1 (default 10) or Line 2 (default 12). If the signal is found, the VITC
Present status indicator is turned on.
NOTE: Input must be auto-timed to use automatic VITC detection.
Enable Auto-Timing
Auto-timing determines if the input is synchronized to the reference genlock
signal. The Profile system records time-base corrected video, whether or not it
is also locked to the reference. If auto-timing is enabled and the signal was able
to be timed into the system, then the Auto Timed indicator is turned on.
If you want to use your Profile unit as a switcher and/or have the output video
correctly timed when in E to E mode, the input video must be locked to the
reference and properly timed to the Profile system. To aid in the timing setup,
all video inputs have auto-timing circuits which synchronize input video to the
