The result on your Program monitor should look much like Figure 14-9; 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 area 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 Scale, Rotation, and Aspect controls in the Tracker tab for
DDR 1 (remember you can double-click the DDR 1 monitor to open this panel).

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