I have imported FBX camera data into the sequencer however it if offset slightly, how can I select the motion path and move the entire camera instead of moving each keyframe one at a time?
These options likely aren’t ideal, but perhaps worth a try:
You could add an actor as the parent of the camera, and move that actor into the right place instead. Afterwards, if you want to get rid of the parent actor, you could bake the camera and unhook the parent actor.
Otherwise, you could select the keyframes in the curve editor and try either the transform tools or adjust the values of the keyframes using the input box in the toolbar. You can type in arithmetic operations in the time and value fields, ie. += 10 or *= 10.
