I am currently in pre-production for a short film which requires a realistic crowd shot. It's set in a concentration camp so the goal is to populate the empty camp with about a thousand prisoners, mixture of young/old/male/female.
I am a university student and in my toolbox I have Nuke, Greenscreen studios, A Red One and I believe I can get access to Massive Prime and a motion capture studio although my tutors have advised me not to go down that route as it will just look crap without having staff that are trained in that particular area.
So my plan at the moment is to get a group of 10 people, shoot them infront of a greenscreen with about 6 different changes of clothes and simply duplicate them to fill up the field. My main worries are that they will have to remain fairly static as our studio is not huge. Also I would quite like to find out if there is anything to pay attention to as far as matching perspectives between the greenscreen plate and the BG plate.
The thought has occurred to me to simply shoot 10 people in our location, roto them and duplicate them which may be a very time consuming process however they would hopefully sit inside the scene very well and we would also not be confined to a small studio.
I have a team of four Nuke users (including myself) who are available to help with rotoscoping and generally getting the job done.
Would love to hear your advice on how this shot can be achieved.
Thanks a lot
