How can I control when a camera starts moving along a curve I am making an animation for my senior project and although I have the actual animation done, I am having trouble with the camera paths. I have multiple camera paths set up (most of which will be following a path) and I wanted to transition between the different cameras as the animation progressed. However, when I start the animation, all the cameras start moving immediately. How can I make it so the cameras wait for a set amount of frames (time) before beginning to move? 

Thank you for any help you can offer.
Just set keyframe where it is still, further in the timeline just before the other keyframes start moving the camera :) 
Like, if you want it to be still in half a second, place a keyframe at frame 12, and then have the other frames placed afterwards. If it is in the middle of a move section, then you need to place a keyframe where you want the camera to be still, and then place the same keyframe at the frame of how long you want the still camera to last :)

If this didn't explain your issue, please tell me, and I will try to understand the issue :)
