To decide if you are ready to solve for the camera movement
1 In the Track Summary panel, choose View > Frame All.
2 For each frame, make sure there are at least four points with graphed
tracked data. Experience has shown that four points is the minimum
average you need to solve a shot.
In the middle frames, such as frame 135, there is less track data. However,
on this frame and all frames in the middle, there are at least four.
3 Look for large areas of red in each track points graph.
Small areas of red are okay. A track points graph does not have to be
completely green in order to solve. In general, if you do find a large area
of red for a point, either retrack over the region or select it in the Track
Summary graph and choose Edit > Delete Region.
4 As a preventive measure, look for blue tick marks in the graphs for flower1
and fenceCornerthe track points you created.
A blue tick mark indicates you moved the track box for that frame. You
may have moved it accidentallyfor example, if you clicked on the track
box to select it. Click on the blue tick mark to go to that frame. Then, in
the pointCenteredCamera view, compare the frames next to this frame.
A shift as small as one pixel can cause problems when you solve.
If you see a sudden shift between the frames, go to that region in the
Track Summary graph, select two or three frames (you can simply
estimate), and choose Edit > Delete Region.
5 Look at the Ready to Solve bar at the bottom of the Track Summary.
Its mostly green and yellow, with little red. The red area is mostly in the
middle because there is less track data there. However, since you meet
the minimum number of points, its worth trying to solve. You can always
add more track points later.
