dark text over a light background for legibility in bright environments.
Night mode displays the menus in light text over a dark background for
reduced glare in dark environments. Set this according to your
preference.
Timing
Press this softkey to access the Edit Const , Field Motion , and Field Ref
pushknobs. The editor constant is a two digit number that specifies two
different parameters for use with edit controllers. Field motion
determines at what rate a transition or Timeline effect is updated as it
runs. Field reference determines on which field a cut occurs or transition
begins.
Edit Const
Since the 8150 can emulate both SMPTE and Sony protocol VTRs, you
may need to adjust the timing relationship between the edit controller
commands and the 8150’s execution of the commands. The 8150
supports two edit timing parameters, know as Command Delay and
Time Code Delay, although these names do not appear in the menu.
These two parameters affect the 8150 only when you use it to run
Timeline effects from an edit controller by emulating a VTR.
Command Delay is the delay (in fields) between the time that the 8150
receives a command and the time that it actually executes it; the higher
the Command Delay number, the longer it waits to execute the
command.
Time Code Delay actually delays the time code that the 8150 sends to
the edit controller. By delaying the time code to the edit controller, the
8150 appears to be "behind" where the edit controller expects it to be,
forcing the edit controller to advance the 8150 Timeline effect relative to
other devices in the system.
The Edit Const value can be a number up to four digits, but only the last
two are significant. The last digit specifies the Command Delay
parameter: it is a single digit, in the range 0 to 9. This gives a maximum
of nine fields, or four and one half frames, of delay. Enter a Command
Delay value if the 8150 executes editor commands too soon relative to
other devices in the system.
The second-to-last digit specifies the Time Code Delay parameter: it is a
single digit in the range 0 to 9. This gives a maximum of nine fields, or
four and one half frames, of delay. Enter a Time Code Delay value if the
