I am running into a problem using the Camera layer in after effects cs5.5. I have several images in 3D space that I want the camera to zoom out from and reveal other layers.
The problem I am running into is this. I create a new keyframe with the movement I want the camera to do (zoom out) and when I play it back, it first zooms in then zooms out. I am very confused and cannot find out why this is happening. I have looked at the graph and it does not show any strange movement, but I can see the position values changing as a scrub across time. What is going on?
Most likely your keyframes are set to one of the bezier types. Simple answer, click the position keyframes, right click on one of them and select "Keyframe Interpolation" and change your spatial keyframes to "linear".
To understand this better though, I suggest adobes help:
