Key Masking
Both upstream and downstream keyers have an adjustable rectangular mask that can be used to crop out
harsh edges and other artifacts in the video signal. The mask consists of left, right, top and bottom crop
controls. Masking can also be used as a creative tool to build rectangular cut outs on screen.
On the broadcast panel the mask is set up for each upstream and downstream key from the system control
mask menu which is available from the EFFECTS KEYS or DSK KEYS menus.
On the software control panel the mask is set up for each upstream or downstream key from the palettes in
the settings tab.
Fly Key
Luma, chroma and pattern upstream key types include a fly setting. If a DVE channel is available the Fly Key
setting allows DVE effects to be applied to the key.
Upstream keyer transitions
The upstream keyers are accessible from the transition control block or the system control. The upstream
keyers are taken on and off the program output using the next transition buttons or ON buttons.
ON buttons
Take the upstream keyers on or off the program output using the ON (on air) buttons as follows:
Step 1. Press the ON button above the corresponding next transition KEY button to immediately turn on
or turn off the upstream key on the program output.
The ON button also indicates if the upstream keyer is currently on or off the program output.
Next transition buttons
Take the upstream keyers on or off the program output using the next transition buttons as follows:
Step 1. Select the elements you wish to transition using the BKGD, KEY 1, KEY 2, KEY 3 and KEY 4 next
transition buttons.
Step 2. Verify the preview output, which will show you exactly what your program output will look
like after you perform the transition.
Step 3. Press CUT, AUTO, or use the fader bar to perform the transition.
