You could create a really fun rig with expressions on the point of interest for your camera.
You could add some expression controls to a null object somewhere. Like a slider whose value goes from 0 to 1.
Then, in the point of interest for your camera, you would put an expression that adds the value of that parameter to (the position of the rocket layer * slider). Then you would start with the slider at 0. This means your camera will just be looking at where the point of interest says. Then, keyframe the slider from 0 to 1 and at (roughly) the same time keyframe the actual value of the point of interest down to 0. Then it will just be looking at the rocket, no matter where the rocket goes.
Awesome! Defiantly sounds like it work, just have to figure out the right expressions lol. Thanks!
EDIT: I actually did it another way that turned out to be way easier. I just created a null and attached the rocket via pickwhip (the entire layer, not just position of the rocket) to that null and did the same thing with the camera(again the whole layer). Worked a treat!
Cool! Glad it worked for you.
