I'm working on a project where I have a camera fly from a wide shot of a world map and end on a specific city. I'm setting this up for a client to use for multiple cities. So fly from the world view to Paris or from the world view into Sydney.
I wanted to have a guide layer that the client can move to the position on the map where the camera move ends and then expression the second keyframe to be the value of the guide layer in x + y position.
Is there any way of adding an expression to only affect the position of the second keyframe?
