We used 'track motion' to track the first part of the MOV. selecting 2 bright points on the ground. And then added a null object and then selected edit target, Null 1. I then tracked the second half of the clip and put 2 points on bright houses in the background. I then added another Null object and did the edit target process again, but this time using Null 2. I then took a still at frame 178 and put it into Photoshop. I then added the 1st castle and scaled it down and removed the sky. I also used the clone tool to add more grass, and then feathered the edges using the eraser tool. I then duplicated the layer so that there were now 3 castles and scaled 2 down so that there was perspective. I then put it back into After effects. I then opened it as a new comp and deleted the background layer. I then had just the castles on my original tracked layer. I then made them a 3D layer and adjusted the colouring to match the images up.
