    Motion Tracker Points-Classroom in a Book

    Petezzzz Level 1

      I am following the tutorials in AE Classroom in a Book.

      On page 324 it shows diagrams of Tracker points.

      Here it shows the two squares indicating Search region and Feature Region.

      In the centre there is a cross which it says is the Keyframe Marker.

      In the upper right of the Search region there is a cross which it says is the Attach Point.

       

      When executing all of the different the motion tracking tutorials on p318-337

      the tracking points that appear do not have the attach points.

      At least they do not have a cross in the upper right of the Search region

      There is only the cross in the centre.

       

      Can anyone tell me whats going on?

      Is my centre cross the attach point or the Keyframe Marker.

      (what is the Keyframe Marker - is this the point at which the position keyframes are measured?)

       

      In one of the tutorials it says to place the Attach point over the object (to be tracked) in the picture.

      If I drag the centre cross, the cross moves without bringing the two squares with it.

       

      many thanks

      Pete
