The tracked region is defined by choosing a primary

Color

using the color picker tool. The

Tracker

follows

this region as it moves and shifts within the frame over time, and outputs the motion data for downstream
application.

Tracker

output from one source can be used to dynamically modify the positioning of other video

sources, when configured to do so in their individual

Position

panels.

A

DJUSTING

T

OLERANCE

Click the eyedropper, and,
while holding the mouse
button down, drag the pointer
over top of the monitor for the
source you want to track (see
Figure 89). The

Tracker

’s

color

swatch updates as you drag,
until you release the button to
finalize your selection.

To assist you while making adjustments, a yellow rectangle is
overlaid on the video to show the effect of the current

Tracker

settings. Watch how this overlay is affected by adjustments you
make to the

Tolerance

value for the

Tracker

. Raise or lower the

Tolerance

value until the result is steady, not jittering or jumping

about.

Hint: The yellow overlay disappears when you close the panel (or
disable the Tracker), but you can show it full-time if you wish. To
do so, right-click the desired viewport, and enable Tracking
Markers from the Overlays options group in the menu.

S

MOOTHNESS

The

Smoothness

setting works just like the

LiveMatte

feature with the same name. Its impact on tracking

data

output may seem minimal, but it can be important when used with the

Advanced Tracking

effect in

M/E

panels (see Section 14.2.2).

L

OCK

At right are controls that permit you to

Lock

certain

Tracker

attributes, preventing them from changing in

the scene.

FIGURE 90

Lock

Scale

to prevent the

Tracker

from automatically compensating when

the scale of the tracked region grows or shrinks during motion.

Likewise, when

Rotation

is locked, the orientation of Tracker output is

constrained.

The

Aspect Ratio

lock forces the

Tracker

to conform to a square (

1:1

), or

rectangular (

4:3

or

16:9

) shape.
