To turn tracking on and off for Pan, Tilt, Zoom, and Rotate:
1 Press the P/T/Z/R ENABLE soft key. The middle four soft keys of the Center panel change to
display PAN ON/OFF, TILT ON/OFF, ZOOM ON/OFF, and ROTATE ON/OFF.
2 Use these buttons to toggle any of these checkboxes on or off, then press BACK to go back to the
other tracking controls.
To interpolate between two separately tracked ranges of frames:
1 Use the transport controls to move the playhead to the first frame you want to place a mark, and
press MARK. A Viewer Mark appears on the tracking bar, identifying either the beginning or the
end of the gap in that clip’s motion tracking data.
2 If necessary, use the transport controls to move the playhead to the second frame where you want
to place a mark, and press MARK. A second Viewer Mark appears in the tracking bar, identifying
both the beginning and end of the gap in that clip’s motion tracking data.
3 To perform the interpolation, do one of the following:
– If you marked both the first and last tracked frames that surround a gap in tracking data, press the
INTRPLT BETWEEN soft key.
– If you marked the last tracked frame in the first half of the clip, then use the transport controls to
move the playhead to the first tracked frame of the second half of the clip and press the INTRPLT
REV soft key.
– If you marked the first tracked frame in the second half of the clip, then use the transport controls
to move the playhead to the last tracked frame of the first half of the clip and press the INTRPLT
FWD soft key.
To move the playhead to different “cue” frames:
– Press the CUE START, CUE LOWER, CUE UPPER, or CUE END soft keys on the T-bar panel.
To use Interactive mode:
1 Press the INTERACTIVE soft key at the left of the Center panel.
Additional button controls appear on the soft keys of the Transport panel, including INSERT
(POINTS), DELETE (POINTS), CLEAR (POINTS), and SET POINT.
2 Do one of the following:
– To eliminate all tracking points, press the CLEAR soft key.
– To add a single tracking point, press CURSOR (above the fourth trackball), use the fourth trackball
to position the onscreen cursor over the feature you’d like to add a tracking point to, and then
press the SET POINT soft key.
– To eliminate a range of tracking points in order to prevent the tracking of an undesirable feature,
use the mouse to draw a bounding box around the tracking points you want to remove, and press
the DELETE soft key.
– To add a range of tracking points to a specific feature, use the mouse to draw a bounding box
around the feature you want to track, and press the INSERT soft key.
3 Use the TRACK FWD, TRACK REV, and STOP TRACK soft buttons on the left side of the Center
panel to perform the necessary tracking.
4 Press the INTERACTIVE soft key again to leave Interactive mode.
