also you can't name the cutscene "camera.sqs", that is a "hidden" sqs. I ususlly name mine movie.sqs. The scene will bob like that if:
1. you made a "hard target" for the camera, like _camera settarget guy1, and then there is no guy1
2. Your variables don't match, ie:
;this creates the camera
_cam = "camera" camcreate [0,0,0]
_cam cameraeffect ["internal", "back"]
_cam camcommit 0
;this is the first view
;=== 8:37:46
_camera camSetTarget [67425.66,85963.05,27.50]
_camera camSetPos [10220.91,3941.01,8.00]
_camera camCommit 0
@camCommitted _camera
see in the 1st 3 lines it is called _cam and the rest _camera? Make sure they all match.
These are the 2 most common probs I have had that cause what you described. Also make sure you are not trying to run "camera.sqs" and "movie.sqs" at the same time
