To fix key fill / key source in key drop off mode
In the Edge menu, switch frame delay mode on (see page 347).
Regardless of the fine key and edge type settings, key fill and key source are
fixed in key drop off mode. In this mode key image has a one-frame delay.
Notes
• This function is only valid on the MVS-8000G/8000GSF.
• This function uses the resizer, and therefore the normal effect of the setting
is not obtained while using DME wipe or other effect that uses the resizer.
Edge fill
When a border, drop border, or shadow modifier is selected, you can select a
signal to fill these edge effects.
The edge fill may be either the signal from the dedicated color matte generator,
or the signal currently selected on the utility 1 bus.
In the case of an outline, there is no edge fill signal selection, because the key
fill signal fills the outline, and the rest of the image remains as the background.
For the emboss effect, in place of the edge fill signal, the emboss fill matte 1
and emboss fill matte 2 signals are used.
Masks
A mask is used to inhibit the effect of a key over a part of the image. This
allows parts of the background which would otherwise be keyed to be
protected, or to correct the key if it is not of the desired shape.
For details of masking operations, see "Masks" (pages 351 and 368).
Key mask and background mask
There are two types of mask: a key mask and a background mask.
Key mask: This masks out a part of the key, which will result in the
background appearing.
