Well you kinda need to script to do a decent cutscene. You can just use the camera effects in the triggers Effects menu but the effect you can prduce are quite limited and basic. To trigger a cutscene though simply add this into the OnActivation field of your trigger:
[]exec "launch.sqs"
That assumes the cutscene script is in a file called launch.sqs. As for doing the camera scripting read through the tutorials. snYpirs tutorial is good as is the camera.sqs tutorial which makes the scripting a lot easier. If you still find it hard to do though then if you like you can send me a copy of the mission and say what you want the camera to do and i'll script you a cutscene.
