Resolving the Box

My aim with this shot was to create the illusion that ghost Georgia was looking at dead Georgia on the road. However, due to the time between changing and doing Georgia's make up, the conditions had changed. Even though only small, the shots didn't line up creating this box around Georgia which made it look unrealistic and fake.

In order to change this, I watched tutorials trying to figure out how to remove this 'box'. After hours of fiddling around on Final Cut Pro, I found the mask tool. After this I outlined Georgia and increased the feathering around her body to make it blend in.

This worked much better. However after watching the clips, the background clip had more movement than the freeze frame of Georgia on the ground. For this reason, i exported it to after effects and tracked the movement in the shot and made both the foreground and background shot have the same path of movement so it looks like one shot.
