Applying this effect immediately causes the display on the

Program

monitor to update, showing the content

of the alpha channel for input

A

(

I

nput

B

is ignored).

The current input

A

source is keyed, so the effect displays black on

Program

out wherever transparency exists in the foreground,

white for full opacity, and shades of gray for in-between blends.

With this in mind, it won’t be

hard to guess what

Show Inverse Alpha

does. In contrast, the

Show Color

effect in this group passes the full

color output of

LiveMatte

prior

to being multiplied by the alpha

channel.

(It might seem as though this would be identical to the original
source, but you may notice subtle differences. This is because of the

Spill Suppression

processing.)

Let’s look at another of the effects in the

Utilities

group,

Color Correction

. Replace the current effect with the

Color Correction

effect

. You’ll notice that M/E 1’s o

utput on the

Program

monitor is now rendered in

monochromatic grayscale. Drag the T-Bar down to affect the

M/E’

s color saturation. Click the mouse on the

Position button

below the T-Bar and drag to modify

Hue

.

Finally, the

Make Legal

effect ensures the output of an M/E is within broadcast signal tolerances.

3D

The

Anaglyph (Red, Cyan)

effect found in the

3D

category is a special purpose tool.

The anaglyph method of displaying 3D imagery depends on stereo video inputs that
are filtered and composited into a single output stream.

In turn, this combined stream resolves into 3D when viewed through special glasses
with red and cyan (blue-green) filters for left and right eyes respectively.

TriCaster provides easy access to anaglyphic technology by means of the

Anaglyph

effect. The effect combines

2 video inputs selected in an M/E. 3D output can then be switched easily like any other source. No complex
configuration steps or tricky control surface operations are required.

LEND

The effects in the Photoshop Blend folder apply well-known blending modes to the A layer in the M/E as
these are blended with the B layer. The resulting compositions can serve many purposes, such as adding

animated ‘bokeh’ style overlays using DDR

clips or adding interest to still overlays such as vignettes or titles.

SECTION 14.6

VIRTUAL SETS

We’ve considered the

Default

and

Utility

effects. Let’s move on to a more glamorous species, the

virtual set

,

presented as

LiveSet™

effects.
