Problem witj motion tracking
I have a problem which I cant solve. In the following clip, I want the appearing wall to diseappear in the left corner while the camera zooms. For the moment the wall stays at the same place which gives the impression that it goes forward with the zooming. I followed a tutorial which seemed to give me the solution but in fact it doesn’t work and I don’t where I made a mistake. thanks for your help.
Here is my different layers:
screenshot_wed_apr_20_19.49.51.pngLayer 3 is the clip of the street before the appearance of the wall (layer 1). In track motion I applied the tracking to the Null1 (I had checked in the Edit option that the target was Null1) and then parented layer 1 to layer 2.
And here is the result:

You either need to do a 3d camera track on the clip and then position the layer you want to comp on top in 3d space to match the angle of the wall you’re trying to paste it on
OR
You can use Mocha to do a planar trackTudor “Ted” Jelescu

Thanks Ted. I tried the 3D camera tracking without success but I made another attempt with Mocha and it worked fine. I made a mistake when I followed the tutorial, my picture did not have the same AR than than the comp! Silly of me. Anyway after different attempts to get a nice shot I’ve decided to abandon this one as my original has a poor quality. At least I’ve learned something! Best Claude
