So I made two cameras, gave them some random animation, and then created a new
camera with a user knob to control which camera's animation is given more
weight. 0.5 would be an exact average, but you can slide it around and animate
it from one camera to the other if you'd like. This could potentially give bad
results if your cameras' rotations were very different (like, going the wrong
way about the axis). If the cameras are supposed to be in similar positions in
space, that probably won't be a problem. Give this a try:
