The task this week was to change the advertisement on the given video.
To obtain the result I have used planer tracker, which helps in tracking a particular plane or a surface and give a 3-D visualisation or a four point play in two us. The difficult part of planner tracking is that it gets messed up if the point given collides or disappear at a given frame. To solve this problem what I did was I change the reference frame to where the points are clearly visible. After the track is done I have taken the corner pin absolute node in order to get the exact transformation of the track that was taken.
This corner pin track was added to the two advertisement which I transformed colour graded as per needed to match the given plate. After this I pray multiplied it so that I can get the alpha of the images on the advertisement that I wanted to be there. After this step I rotoed the pole and merged it along with the main plate so that it is on the top of the advertisement as I wanted to be.
