I did motion tracking and have a target layer attached to the motion tracking and it the target is masked. It is working great. I corrected some of the keyframes in the motion tracking and really fine tuned it.
Now, I would like to continue the same motion tracking with the same target for the rest of the clip. Can I continue the tracking? I notice that if put the playhead where I want it to continue and I go to the tracker panel and click on track motion, the tracking that I've already done comes undone and is no longer working.
Is there an easy way to continue the tracking where it left off? If that is not possible, is it possible to use the same target and do more motion tracking with another motion tracker?
I think you're hitting the wrong switch. When you open up the tracking (you have to do it in the layer view, of course), you should be able to use the Analyze Forward button for the tracker.
Here's a boatload of helpful information on Motion Tracking.
