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.

Now would be a good time to test the effect of the

controls in the
Tracker
tab for
DDR 1
(remember you can double-click the

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.
