keyframing parents

i am animating an aerial dogfight and would like to have part of it spent with the camera following at a constant distance from one of the fighters, i think this would be achieved by parenting the the camera to that fighter but i ONLY WANT THE CAMERA PARENTED TO IT FOR PART OF THE ANIMATION. how can i keyframe the camera’s parentage to achieve this, if keyframing parents is not possible what easy methods could i use to get make the camera follow( that means position and rotation in 3d space) the fighter. thanks.

Child of constraint.


how do i make this change with time so that the camera is only child of the fighter for a part of the video. i cannot seem to find a way.

You keyframe the influence of the constraint.

it appears to be working THANK YOU @AlanK !!!
