Tektronix Grass Valley 3000 - Manual (Page 101)

2-65
Operating Notes
If an Editor or a GPI trigger initiates one of these functions, it will
produce the same effect as a control panel change. That is, the
initiation of any of these functions will be delayed until the
beginning of the selected dominant field.
Summary. If you are recording the output of the Model 3000 on
video tape and will be doing post-production editing of the tape,
it is recommended that you set Field Dominance for a specific field
(either
FIELD 1 or FIELD 2 ), and leave it at that setting. This will
ensure that all changes will take effect consistently on the same
field.
Using the Mask Draw Feature
This section describes some tips and tricks about using mask
draw. See The Mask Store Menu descriptions for how to select/
manipulate mask draw functions.
NOTE: You may want to browse the descriptions below; then
experiment with the brush and screen selections provided on the Mask
Store Menu.
1. Using the STRAIGHT and FREEHAND draw modes (selected
with the DRAW MODE button).
STRAIGHT automatically draws a straight line between two
cursor points. To make the first point, press the pen onto the
tablet; then lift up slightly. Keeping the pen about a 1/2 inch
above the tablet, move the pen to where you want the straight
line to end. Press the pen down for the second point and to
complete the line. (A “temporary” line on the monitor
provides a visual cue as to where the line is going.)
