[MASKS-Display menu] Per ME only one b/w video signal can be selected as
mask signal. Hold down the ”BUS” softbutton while an input signal is selected from
the AUX bar.
CLIP and GAIN for this mask bus are adjustable with the TOP (= Gain) and BOT-
TOM (=Clip) knobs of the MASKS-Box-Modifiers.
This is to create rectangular mask shapes.
Please refer to the Operations Manual (DD5/10–>section 2.10 or DD20/30–> sec-
tion 2.11) for further information.
The masks that are generated with patterns can only have the shapes a Wipe
Generator can produce with its modifiers.
If customized masks are needed they can be created with the help of the MASK
STORE. Therefore select the MASK SOURCE to be the Mask store.
[MASKS-Display menu] –> push MaskStore softbutton (lower center area).
This activates the MaskStore output to be the source for the Keyer mask. Now the
store feeds the mask but it still has to be determined which source signal has to be
fed to the MaskStore.
For the following example PATTERN 1 is used as a brush to paint a customized
mask. Hence, this becomes the STORE SOURCE.
– Set up the MaskStore
– Push the Stores Menu selection button
– [STORES-Display menu]–> In the menu push the Mask button.
NOTE: With more MEs (DD20/30) you have to verify that the autodelegation
had put you into the correct ME.
If you must change:
– Select the destination ME by stepping through with either repeatedly pushing
on ”ME” or ”MASK”.
– Select PATT 1 (or PATT 2)
PAINT A MASK (not possible with DD5 !)
[STORES-Display menu] –> Switch PaintMode ”ON”.
This activates a ”paint cursor” in addition to the mask that is already previewed. At
the same time the MaskStore immediately freezes.
[STORES-Display menu] –> Push Clear to erase all contents
– Move the cursor to the place you want your object and hit Paint.
For CONTINUOUS DRAWING leave Paint active and move
the cursor, when finished, deactivate Paint.
NOTE: All mask placements will be recorded as long as Paint is active. Field-
Flicker can occur when the paint brush is moved too fast. To over-
come that problem switch to Field mode and by stepping through
select either Field A or Field B to be displayed twice instead of a
Frame mode. Of course this results in half a vertical resolution.
