After refining your feature points, you may not need to retrack the entire sequence. You can use Update Track to analyze a specific frame range.
| 1. | Refine your features using the controls described previously. |
| 2. | Click Update Track. |
A dialog displays allowing you to set the frame range to update.
| 3. | Set the required frame range and click OK. |
CameraTracker retracks the selected range and combines the tracking data with any existing tracks.
NOTE: You may notice that CameraTracker performs some analysis outside your selected frame range. This can be necessary to extend existing tracks into the update range, avoid creating duplicate tracks, and to combine the new tracks with existing tracking data.
