First big project with FCP. Music video with 4 camera angles and multiple takes with different wardrobe, all shot in front of green screen. Plus lots of short B roll cutaways (non green screen). What's the easiest editing approach? I can't figure out how to use the Multicam method with green screen and do cutaways. Thanks!

Hi - I've attached a FCP course on Compositing and Visual FX to the thread [More Info, above] -- maybe there'll be something in there that'll be helpful.. I'm an audio guy myself so I can't advise, but pehaps a FCP user/guru will weigh in..

Thanks Joe, Audio guy here too. I do hope a real pro weighs in here. What I want to do may not be possible directly. Maybe it requires doing all the multicam edits first and somehow turning that into a new single video or clip, then dealing with the chromakey (green screen) and B roll cutaways. But I have no clue.

OK, so you film each shot with the music playing along (cameras must all have mics recording the boombox playing the music actors/musicians are lip syncing to), so all clips should be able to sync in a multicam by sound. Then you have your basic multicam. I assume you've gotten this far. Green screen shots should be done the same way. Then apply the keyed to the clips on that angle, in the angle editor. OR if you know what the backgrounds they're going to need, create a Compound with the green screen keyed over its background, add that Compound into the multicam. Or manually add clips as connected clips to the multicam in the Project's timeline.
