Copying and pasting keyframes from a source camera to a destination camera (with no keyframes inside) remove all the keyframes from the source camera I'm trying to copy all the keyframes from the camera 1 (called camera) to the camera 2 (called voodoo_render_cam) that's connected to an empty. What I do is : (in the dope sheet window) I select first all the keyframes of the camera 1 and then the camera 2 (it has no keyframes) and then I press CTRL + L and then "animation data" and happens that both the cameras have anymore keyframes embedded. All the keyframes are deleted. What's wrong ? what I'm trying to do ? I would like that the camera 1 (camera) disappear and that the camera 2 (voodoo_render_cam) take its place. It could also not disappear but I want that the camera 2 is placed on the same position of the camera 1. Maybe there is another way to do that. I have attached a video to show you what happens. 



you can find the blender file here.
What you need to do is simply select the camera you want to copy the keyframes to, then select the other camera which has the desired animation, and hit ctrl-L and select Animation Data.  You have to select the camera with the desired animation LAST
