By the way, if you're totally new to After Effects, you shouldn't start with motion tracking as the first thing that you do. It's somewhat complex for a first project. I strongly recommend that you methodically work your way through the getting-started materials here.
I've been through that page - It doesn't work as of step 2.
I've got a single file in my timeline, which is selected. I click track motion, but under edit target I can't select anything.
And I realize it's not a great first step, but it's what I've got in mind for this project. I've used FCP in the past for editing, but this year bought cs5 so I'm learning premiere and AE at the same time. My son's soccer end of year party is in a couple weeks and it is what it is

If you've only got one layer in your composition, and that's the one that you're tracking, what do you expect to be able to change the target to? The point of motion tracking is that you track motion in one layer and assign that motion to a different layer. If there's not another layer to assign the motion to, then you can't edit the target.

I understand your desire to get started on doing something "real", but the truth of the matter is that you have to learn the basics before you can be successful with this program. Please, read this page. All that I've done for the past six years is teach people how to use After Effects, and that page summarizes that experience.
If you insist on starting straight into a project involving motion tracking, at least watch the tutorials that I pointed you to in my previous post (here).
Thank you for your reply again. What I am trying to do is create a track of an animated cartoon (simple stick figure with a circle for a head) and then use that to take another source (video) and put someone's face into that cartoon as it jumps around the screen. I thought I had to create a motion track on the cartoon and then add the video later.
You're right i'm sure I'm in over my head. I've actually watched quite a few of the adobe videos and also I'm a subscriber to lynda.com and have watched numerous videos on AE as well. It's just actually doing that's confusing me.
I've looked at those tutorials you listed (most of them before I asked!) and I'm still obviously missing something so I'll go back and look again.
Thanks so much for taking time to help me.
Did you create the cartoon? Tracking only works on footage that's a movie or on pre-composed animations. A little more detail about your project would help.
Yes, it's in .mp4 format. I've gone through and did all the motion tracking using the boxes, that works fine. it's just I can't select or apply. It's an eztoons creation, very simple.
I think that you may still be missing the point that I tried to make earlier. If there's not another layer in your composition, then there's nothing to apply the motion tracking to. Add another layer to your composition; then you can apply the motion tracking data to it.
Please, watch one of the motion tracking tutorials that I pointed to (such as this one) and follow along with the steps that are shown to you. Then, once you've done this yourself along with a tutorial, it may make more sense.
the answer was:
Layer, create new, null object
Apply to that layer
Parent my object to the null.
I read through quite a few of those links, but actually found it at this video which was VERY helpful:
Thanks to both of you for trying to help me. I will continue to work through the tutorials and learn more, this product seems very useful and fun, but it's also a whole new vocabulary and workflow to learn.

Possibly you forgot to set "Track Type" to "Stabilize". It's probably set (by default) to "Transform". I had the same problem and spent two hours on that... Unfortunately Todd's answer, "RTFM", wasn't very helpful.
thanks for your help mate! :-) i'm using AE CS5.5 and i have a same problem as pprioroh. After you mention about "Track Type" . Thank's again.
that works, thanks man.
For me, I duplicated all my layers and and deleted the track points on my duplicated layer. Then I went back into the tracker and target layers could be selected. Pretty simple, but extremely annoying.
Every problem described in this thread is the result if improper workflow.
To figure out how to use Track Motion, Camera Track or any of the other built in tracking features that come with AE just type the name of the technique you are trying to use in the Search Help field at the top right corner of the app and check out the community resources. They are filtered and in almost every case you'll get vetted training that teaches you the proper techniques for using the tools.
i had the exact same problem when i wanted to stabilize motion of my video layer.
exactly like griestopf has pointed out: the problem was that initially the the tracker wasn't set to "stabilize motion".
SOLUTION is to copy the old tracking points keyframes and paste them to a second "stabilize motion"-tracker
1: select the tracking point(s) from "tracker 1" and copy (CTRL+C)
2: create a second tracker by clicking "track motion" once more, but this time click on "stabilize motion" in the tracker settings.
3. edit target should now work.
4: paste (CTRL+V) the tracking points from tracker 1 to the new tracker. and delete the old ones which are empty of keyframes
5: click apply
6: you can now delete the old tracker 1
I just found a workaround for the problem. I was using a "replace with after effects comp" file generated in premiere.
!!! I opened a totally new AE comp and dragged my clips in from the finder and set the ins and outs. Then added a null. Motion tracked my clip. And tada! The "set target" dialogue was enabled!
I know how to motion track. I've done tons of it.
So it's a glitch, one of several that come out with every update.
