Attached camera shakes violently(camera.sqs)

[dcal 16]

I am having some fun with camera.sqs and scripting but when I attach a camera to a vehicle or aircraft the camera or the unit(can't tell which) shakes/stutters violently as if the camera cant match the speed of the unit. All the shots that involve tracking and un attached cams work very well so I am not sure why the attached cams shake so much. If someone can take a look at this code and get me out of a jam I would be very grateful:

titlecut [" ","BLACK IN",1]
_camera = "camera" camcreate [0,0,0]
_camera cameraeffect ["internal", "back"]

_showcinemaborder false;

#loop
;comment "21:21:37";
_camera camSetTarget plane1;
_camera camsetrelPos [-3,6,3];
_camera camPrepareFOV 0.700;
_camera camCommitPrepared 0
goto "loop"

_showcinemaborder false;

~20

;comment "20:51:37";
_camera camPrepareTarget plane1;
_camera camPreparePos [2392.08,3411.32,4.77];
_camera camPrepareFOV 0.519;
_camera camCommitPrepared 30

~29

_camera cameraeffect ["terminate","back"]
camdestroy _camera
end1=true;
exit;
