19. Enable Follow Tracker (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.

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).
UTILITIES
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.
