Can we "LOCK" an effect to a relative scene point?

What do I mean by this? Well, let's say I add an effect, for example a still of the Batmobile sitting in a parking lot.
The problem arises when the camera is not on a tripod. When the camera is handheld or during any camera movement like pans, I have to try and match the car's location to where it should be in the frame, frame by frame.
This is not only tedious, but it doesn't work very well since the matching done manually is never perfect.
Well, you might say to simply lock the camera down on sticks for every such shot, but that's not a good answer, since sometimes you HAVE to have camera movement (say, during a close-by explosion).
I think Adobe After Effects can lock an effect to the screen, so if the camera shakes, the effect follows the shake.
Is there something similar in AlamDV?

Actually, i don't think after effects can do that.

I saw a demo of AE at DV Expo in L.A. last December. But in the demo, , the guy added his own camera shake and slight movement (a small pan) from within AE itself, then added the explosion. The camera shake, movement and explosion together became a VERY effective illusion.
I guess this is different than an in-camera shake or movement since if all the effects are in AE, they can easily lock themselves to each other, but locking to an actual camera shake would be very difficult since the program would have to analyze the underlying pixels, and their movement.

AlamDV2 can easily do camera shake as well, using the frame mover.

No, you misunderstand.. I was talking about ADDING camera shake as a special effect then having whatever other FX that were added (i.e., explosions, bullet tracers, etc) all MOVE along with the shake.
But I also wanted to know if the flip side of that was possible. That is, let's say I already have a slight camera movement (handheld shot, say) and I want to add something, like a still of Darth Vader in the background. Well, he would have to "move" along with the slight camera movement or it wouldn't look right. But it seems this part is not possible with either AlamDV or AE.

I'd recommend adding your effect BEFORE you add the camera shake effect
as for adding the effect to the pre-shaken camera, find ICARUS, then track your shot, and use a 3d application to add your still in. . . it's the only way I can think of to do it. . .
aside from manually trying to track it yourself, frame by frame in ALAMDV or AE. . .

Isn't this feature known as motion-tracking? I believe AE Prod. bundle can handle it; I may be wrong though, 'cos I'm a goon

will alamdv3 be able to do this.
you film a wall with a blue spot in the middle with a handheld camera and you shake the camera.Would you be able to have the blue spot as a landmark and lock an effect on the blue spot

No. You need a motion-tracking app for that. Icarus is a free aplication that can do this very well.
It is much, much simpler to lock off you camera, add whatever effects you want, and then add the camera shake afterward. All of that can be done in AlamDV, and it will ensure that the effects are locked in place as the frame shakes, so everything will move in unison. It also gives you much greater control over the shake, 'cause you can fine-tune it to shake exactly how you want.

yeah moebius AE PROBUNDLE can do cam tracking easily
i do it all the time
