Fifteen seconds of black preroll are automatically recorded before the encoding sequence starts. On
recorders that are controlled via the RS 422 interface, this preroll always starts 15 seconds before the
specified start of the sequence. This means that encoding starts at the specified timecode minus 15 sec-
onds. (On some devices controlled via i.Link, you can change the preroll in the player settings.)
Master Tape TC and Timeline TC
There is a direct relationship between the start of the striping timecode and the start of the Timeline
timecode (see also Set Start Timecode on page 417). To calculate the start timecode for striping, subtract
the duration of the leader from the Timeline’s Start Timecode.
A standard leader is usually 60 seconds of color bars with a reference tone followed by a 30-second black
image.
For example, if your Sequence starts at 00:02:00:00, enter a value of 00:00:30:00 for the leader (or
09:58:30:00 for a sequence starting at 10:00:00:00, for instance).
