Left Pattern Display
The pattern display has two side-by-side image windows and a series of status bars. The
window on the left shows the pattern initially selected, while the one on the right shows a
real-time display of the current pattern as tracking progresses.
As the onscreen controls move while tracking, the display in the leftmost window updates to
show the pattern. As the pattern moves, the vertical bars immediately to the right of the image
indicate the clarity and contrast of the image channels.
The best channel or channels get selected for tracking based on clarity. These channels have a
gray background in the vertical bar representing that channel. You can use the automatic
tracking or override the selection and choose the channel by selecting the button beneath the
channel to track.
Under normal circumstances, the channel selected shows in the pattern display. If the selected
channel is blue, then a grayscale representation of the blue channel for the pattern appears.
The image is represented in color only when you activate the Full Color button.
Override this behavior by selecting the Show Full Color button beneath the pattern display
instead of the Show Selected Channel button.
TIP: Because Fusion looks for the channel with the highest contrast automatically, you
might end up tracking a noisy but high-contrast channel. Before tracking, it’s always a
good idea to zoom in to your footage and check the RGB channels individually.
Right Pattern Display
The pattern display on the right indicates the actual pattern acquired for tracking. This display is
black until tracking the selected pattern for the first time. The pattern display becomes active
during tracking, displaying the pattern that Fusion acquires from frame to frame.
As the tracking occurs, the pattern from each frame accumulates into a Flipbook, which can be
played back in the pattern window after tracking by using the transport controls at the bottom
of the window.
While the track is progressing, the vertical bar immediately to the right of the pattern shows how
confident Fusion is that the current pattern matches the initially selected pattern. A green bar
indicates a high degree of confidence that the current pattern matches the original, a yellow bar
indicates less certainty, and a red bar indicates extreme uncertainty.
After tracking, the pattern display shows a small Flipbook of the track for that pattern to help
identify problem frames for the track.
