Hello! I have seen this cool transition on this video https://m.youtube.com/watch?v=j48LdlUvyww
It is the very beginning of th video where he transitions the raw footage into the colour correct and blur. I know there are 2 - 3 layers of the same footage with masking over them. However I have no idea how he managed to track it so that the camera "enters" the windows to cross over into a new transition. I recreated a similar footage with stabilized camera. I have access to AE and Vegas Pro, however I am quite new at AE and I certainly do suck at tracking motion (no idea how rotation and scaling works, will figure out later). Thanks ahead for any advices, especially if you could provide me a step by step tutorial based on your analysis.
