The footage that I created is now in After Effects. So far I have done a sky replacement. The first step that I did was feathered out the part of the video I wanted to change. I then added a solid and covered the area i wanted to stay the same. The area i wanted to changed i used the pen tool and masked around it. As the sky was the only part selected i added a null to the project. I then found a high contrast point in the sky and placed the null there. When the null was in place i then motion tracked it and it followed the sky. When this was complete i parented up the null to the footage that i had taken. The sky that i have added is a purple nebula sky.
