to bad that site is down so much

u can find a better world editor there 2. it has more cinematic options. here is a start for you if site is down for couple of days.
event- (event, like time elapsed is 2 seconds)
actions- turn cinematic mode ON for all players
here u can do things u wanna do in cinematics.
transmission from unit. makes a unit talk (like in campaigns but no voices) with txt you want.
apply camera object makes the camera go to the one you specefied (and made in camera pallete)
and apply filter is that screen turns black,white, shows the panda

or others. great stuff to use!
and to exit just turn off cinematic mode for all players

(letterbox mode is same but cinematic mode sounds better

)
this are the very basics.
