Translate Z Location of object for every frame? I am brand new to Blender and 3D modeling in general so please bear with me if I use incorrect jargon and terminology.

I got help from a friend making a video in Blender, but as I got further into the project I noticed the camera is to close on every frame. Sadly my friend went on vacation and is unavailable for a while so I have no source for help. To clarify I am looking for a way to change the Z location for every frame at the same time instead of going through and dragging the blue arrow frame by frame.

Any help is appreciated as I am going through multiple websites and only finding words and terms that don't make sense to me.

This is what I see on my screen, hoping it helps
There are a few ways to do this, but essentially you want to parent a camera to the path of the old camera. The easiest way to do this is to:


duplicate the camera SHIFT+D
remove the keyframes on the second camera
parent the second camera to the first camera CTRL+P
change the Transform widget orientation to Local
move the second camera back on the local Z axis
it will still move and pivot with the original camera's orientation.
Select the second Camera and click Set Active Object as Camera CTRL+NUMPAD 0
you can also optionally hide the first camera via the outliner if you find it distracting
