Duplicate:
forces a second copy of the time code to be inserted on the 2
nd
line following the selected line. For
example, selecting line 14 for time code insertion, and turning timecode duplication
ON
, will result in time code being
inserted into both lines 14 and 16. Note that time code cannot be inserted on lines outside the allowable range, so for
example, if line 19 is selected for time code insertion in a 525 line output, and timecode duplication is turned
ON
, the
duplicate time code which would have appeared on line 21 will not be inserted because the upper bound for time code
is line 20. Thus, the timecode duplication function has no effect when the selected line for time code is 19 or above for
525-line outputs, or 21 or above for 625-line outputs.
