BORDERS
FIGURE 9-12
The Edges tab for TriCaster Advanced Edition systems also
provides each DSK, KEY and M/E layer with quick access
Border preset slots (Figure 9-12) to supplement the scale,
rotation, edge and other controls. These powerful border
effects can include full color overlays, backgrounds, matte
layers for ‘keyhole’ effects, and shadows.
This feature allows you to freely scale, position and rotate
various sources, add custom borders, overlays, shadows,
and so-on, over custom backgrounds or even live or
animated sources – all without special skills or resorting to Virtual Set Editor. Since these are per-layer
Positioner effects, you can easily create custom multi-box compositions in TriCaster’s M/Es.
In addition to hundreds of supplied borders, you can easily create elaborate custom effects using Photoshop
®
.
A template PSD file is supplied to assist you to do so. You will find it in the Borders folder, at
C:\TriCaster\Effects\Borders.
You will find it is easy to create a custom border. You need merely define a Photoshop format file with three
(rasterized) layers. The uppermost layer contains foreground elements (such as a bezel). The next layer is
treated as a mask based on opacity, and defines the part of the source image that will appear in the result.
The ‘bottom’ layer supplies a background to appear behind transparent parts of the source (as, for example,
when LiveMatte is applied to a source).
Hint: Since the opacity of the mask layer can vary between fully opaque and fully transparent, you can
create soft-edged effects such as vignette effects. Also, as foreground and background layers can
optionally be empty, a simple opaque shape in the mask layer can serve a variety of imaginative results.
