Can individual tracking points be edited in After Effects? I solved a rather long scene in After Effects for camera tracking.  Later, I realized that the tracking point I chose "jumped" out of its stable position for a split second.  This only became apparent after I had attached a graphic to that point.

Re-doing the analyze/solve steps is rather time consuming.  I was wondering if the tracking data for the point I have chosen is accessible and whether it is possible (and easy) to edit out the offending data point/points.

By the way, if I got what you mean you just have to move with the Selection Tool the keyframe on the Composition screen.

For making the path smoother and more accurate the sub-Pen Tool called Convert Vertex Tool.

Finally, on the timeline thanks to Graph Editor, add dynamicity to the animation in-between frames (delay and advance).
