Overlaying an object/image exactly on top identical object/image

Hi guyman,

Did you solve this issue yet? Please let us know.

Thanks,

After Effects comes with motion tracking, corner pin tracking, camera tracking, stabilize motion, and Mocha AE. The right tool for the job depends entirely on the shot. More than one tool will probably do the job so the most efficient tool also depends on the shot. Sometimes the best option is to motion stabilize the shot. Motion stabilize means that you pick one or two areas of significant detail to track and stop that part of the move from moving in the frame. You then add your image and use distortion tools as necessary to fit your image to the frame, then you put the motion back in the shot and add the motion to the inserted element using a null, some expressions and parenting.

Another option is to use Camera Tracking to create a camera in AE that matches the movement of the camera in your scene. You then insert 3D elements into the scene that attach themselves to fixed geometry in the scene.

Another option is to use Mocha to track surfaces in the shot and then use that tracking information to insert other elements into the scene.

Without seeing the specific shot you are using in your project or at least having a very detailed description of the shot, it's very hard to recommend the appropriate technique.

Here are a few examples of the different types of tracking that can be used. The first uses Mocha to track the front of a TV and then inserts a video into the screen. You could just as easily insert a still image:

Here's a simple one using stabilize motion and an expression. Sorry - no audio.

You can find more information about tracking and replacing objects by typing Stabilize Motion or Track Motion, or even Replace image in the search help field at the top right corner of AE and check out the community resources. You usually get better results than using Google.

If you show us your shot we can suggest an efficient solution to your problem.

Please show us exactly what you want to do with screenshots so we can offer a specific workflow to your needs. This could be a couple of different scenarios so screenshota would help.
