I have been working with Sony Vegas Pro 9 for a little while now and am working on a project with talking heads, having a person's head overlay a moving and walking Spartan soldier in Halo 3. I have been able to accomplish this by finding "linear" (unchanging speed of motion) for the spartan's head which I can add keyframes - a very slow and tedius process.
Is it possible to apply some sort of "Automation" with track motion by moving the head overlay in real-time along with the spartan's head? For the best precision, I am also looking to do this while the track is playing in slow motion.
