At first I was creating a null and camera and then parenting the layer to the null using the lasso. When I try to parent the second layer to the null it doesn’t take on the properties ie it still moves across the screen instead of staying still.
Then I discovered that you could create multiple nulls and I tried this. But again I got the first element (an imported png of the map marker) to stick to null one, but then the second ( a shape layer) would not stick to any of the nulls.
I don’t know if there is a particular order of doing things that I am missing, but I am creating all of the layers on the video layer, then running the camera tracker then trying to lasso them.
