To fade in from black you must make a script called
fadein.sqs and in the script put this line of code.
titlecut ["","black in",2]
~2
exit
that will make the screen fade in from black in 2 seconds
and make the script wait 2 seconds before exiting out with the exit command and now to make the people stay in one spot put this in there init feild.
this setBehaviour "STOP"
that will make them stop moving and stay wherever they are that should work. if it doesnt than im a lot rustier than I thought i was been away from the OFP scene for about a year and thats what I remember hope tha helps.
