Hi April,
There are a couple ways within FCP, but for more advanced stuff, go to Motion or Live Type (though i think LiveType is virtually completely contained within Motion). anyway in FCP…
go into your Effects bin in your browser. then to Video Generator / Text / Crawl (or Scrolling Text). you can do more advanced stuff from right within FCP by going to Effects/Vid Gen/Boris. play around in there for awhile! : ) another way to get to all of the above text thingies is in your Viewer, click on the bottom right button and you’ll access the same stuff.
i hope this helps, or hopefully i haven’t restated the obvious for you!
thanks for helping out a bonehead,
jtn
