Resizing a pattern box to fit the tracking point on the ray gun.
TIP: The magnified pattern box does not take viewer LUTs into account. When using
Log content, it may make it easier to position the tracker if you temporarily insert a
Brightness Contrast node between the source content and the yellow input of the
tracker. You can use the Brightness Contrast node to temporarily increase the visibility
of the region you are tracking.
Refine the Search Area
A second rectangle with a dotted border surrounds the pattern box. This is the search area.
When progressing from one frame to another while tracking, the Tracker analyzes the region
defined by the search area, which surrounds the last known tracker position in an attempt to
relocate the pattern. The larger the search area, the better chance you have of successfully
tracking fast moving objects, but the longer the track will take. However, there are some ways
to optimize tracking for specific content.
For example, tracking a pattern that is moving quickly across the screen from left to right
requires a wide search area but does not require a very tall one, since all movement is
horizontal. If the search area is smaller than the movement of the pattern from one frame to the
next, the Tracker will likely fail and start tracking the wrong pixels, so it’s important to take the
speed and direction of the motion into consideration when setting the search area.
You can resize the search area by dragging
the edges of the dotted outline.
