(Figure 178).


The result on your

Program

monitor should look much like Figure 179; full motion video appears wherever

the orange card appears in the foreground clip. This is the standard setup for the

Advanced Tracking

effect,

though it’

s possible to use it in different ways too.

Further Notes: Advanced Tracker 2 provides much improved compositing. (The original effect is provided for
legacy purposes, but might also produce a better result in rare cases where a source has embedded
transparency). Among other benefits, the newer effect performs spill suppression at the edges of the tracked
region. Using the size (etc.) parameters of the tracker, the region being tracked can be made slightly larger to
taste, to moderate this effect.

Effects can take other forms as well. We’ve looked

at the

Default

effects group; now

let’s consider

Utility

effects.

If you were following along in the previous section, replace the current effect in

M/E 1

with the

Show Alpha

effect from the

Utilities

group.
