Here ya go..
cutrsc ["binocular", "plain"]
showcinemaborder false
_camera camSetTarget Tank
_camera camSetPos getpos yourman
_camera camSetFOV 0.231
_camera camCommit 0
And here is the explaining :
cutrsc ["binocular", "plain"] : Makes the screen look like a binocular
showcinemaborder false : Removes the black line at the top and at the bottom during the cutseene
The rest are usual camera commands.
To get the screen look normal again :
CutRSC ["Default","Plain Down"]
showcinemaborder true
Just ask for further explanation if you need ;D
