using mask and tie up underlying layer in the mask
To explain my problem well i try to describe a simplified situation and i hope you can understand. There we go.
First: it´s about pictures (but i think there is no difference with movie).
Main picture: exterior, buildings in a street.
Second pictures, second layer: interiors.
The interiors are not overlapping eachother in the timeline.A slow pan alongside the windows of the buildings.
In 5 windows i made a mask so you can see what´s behind (the interior).
Problem: The moving alongside the buildings (the main layer ) influence the layer underlying, the cut-out of the interiors are moving too, and i don´t want that.
During the time the buildingwindow is the screen, i want to control seperate what is happening in the interiors (y can say i want to fix the underlaying picture of the interior).
I tryed with the “compositing child”, but it didn´t work.
Is this the way and yes what did i do wrong? Or i have to do it another way?
I hope i was clear, so not, please ask me.
thanks, herman.my goal is making pictures in motion

You are really close. What you need are 3 tracks. The top track is the controller. It will act as your camera. The second track is your building with the windows and the third track is the interior scene.
(1) Add three video tracks (Ctrl+Q)
(2) For each of the three tracks enable Track Motion with 3D Source Alpha option.
(3) Make Tracks 2 & 3 a Compositing Child of track 1
(4) Enable Parent Composite Motion on Track 1 with the 3D Source Alpha option.
Your tracks should look something like this:
Here is the key: You need to open the Track Motion for the Interior track (3) and increase the Position Z to move it back in space. This will create room between the windows and the interior. You should also scale the interior up a bit to compensate for moving it back.
Finally, use the Parent Composite Motion of the Controller track to move past the windows. You should get a nice parallax affect between the windows and the interior.

Herman,
If I understand correctly, you mask the window of the upper (street view) track to see inside. The track below must have motion too to make it look like you are passing.
To do this the right way you will need 3D motion. You will have to change the z-axis for the lower track and put the motion on a parent I am not very skilled at this, but John Rofrano is. He will probably jump in and help you out.http://www.narrowroadmedia.com
