Test 4 - Moving footage

I have returned to a moving piece of footage to see if there is any way to fix the problem I had of the light moving with the footage. I came up with this. Although not in anyway perfect or even good, it works, and is the first step in a long road of testing.

To achieve this effect, I shrunk the footage, and moved it as the camera moved, aiming to keep the background static in every shot. I then created the light and made it follow the subject. As these warped perspective, I had to try to warp it back using the warp tool, and setting two key frames, one as the camera began to move, and another at the end. I also copied this effect on the light, although this is not very obvious. To improve on this effect, I need to use motion tracking on a rendered version of the film to track the square of film wherever it goes, and make it static, and center it. This should then look better. However, I could not get the motion tracking to hold, so will hopefully try again later, or find a tutorial off the Internet.
