Dig RGB Lock source [Off]
14.1 Dig RGB Lock source
Normally, any RGB Lock source remains as an unprocessed signal with any
Program source simply inserted into it. (For instance, with 'PIP' as the Lock
method, the scaled Program source image would just be inserted into the RGB
Lock source. Underlay would thus be impossible, since the RGB source's signal
is not processed and therefore cannot be compared to any key levels.
When 'Dig RGB Lock source' is active, and the Program source is a CV, YC or
SDI input, the RGB Lock source IS processed and mixed digitally. Thus switching
Program sources would cause the scaled Program source to fade into the Lock
source (instead of fading to black).
It also means that underlay now becomes possible with an RGB Lock source -
i.e. with the Program source being scaled and locked to the RGB Lock source's
resolution, but with the (unscaled) RGB Lock source appearing 'in front' of the
Program source (in other words, the Program source is underneath - hence the
term Underlay).
Notes:
1. This setting defaults to Off to preserve the same functionality as earlier
firmware versions.
2. The On state has no effect when the Program source is an RGB or YUV input.
3. When On and Locking to an RGB connector source, seamless switching
between RGB and non-RGB inputs will have glitches (as the unit needs to switch
between two very different operating modes).
This function is a toggle function so when you press the Menu Select knob, the
feature is turned “On” or “Off” and there are no flashing brackets involved.
