why not parent the camera to a null and keyframe it only in the desired places? you can set the null at the focal distance of the camera before you parent the camera if you need to control the POI of the camera.
I could do this, but I'd lose all of the "charm" of the hand-held camera. I know I can use a wiggle expression, but I was hoping to find a way to work with the data I have.
This seems like the only sensible way to move forward, though. Thanks!
Wait a second I now realized you said "locked" ib red. do you mean the graph editor? I am not sure how you wo lose any movement if you are just offsetting with a null. if you want you can share a few screenshots or a video and maybe there is a way to help you get what you want.
