Hey guys. I recently bought Compostie Lab, and i've only messed around with it a little, but I know it's really powerful and can do a lot! Well, my friends and I have a show called Totally Drama! (check out www.youtube.com/totallydramatv) and I write, film, and edit everything! It's great! Anyways, for our finale episode, were making a number of music videos! So here's where I'm stuck--

I'm filming them behind green screens (I bought green screen paint and am going to paint flats) and they will be acting like their "famous". Well we want to have multiple clones of them, then add it all together with the background picture to make it look like screaming fans! How do I do that??

Also, what is the best way to film green screen outside? We are setting up the flats and stuff outside?

Thanks a bunch!

Hey there

Glad you found Composite Lab and are enjoying it thus far.

Basically for the effect, you'll need to shoot your actor(s) on the greenscreen and then you can duplicate that footage or just take mulitple shots of it, and import them into Composite Lab. With the greenscreen videos, you can move them around your canvas and position siethem the way you want. Then you can simply key out the green footage, and import your cheering crowd video or still. That should do it.

Clab Cloning Tutorial and Cloning Tutorial 2 (not exactly what you want, as you're using a green screen as apposed to a non green screen background)

As far as a Green screen outside, that is one way to do it. After all, the sun is the best light source, and it's free. Just keep an eye on the position of the sun, especially if shooting throughout the day, because, well, it would be in the sun's nature to move a bit. Shooting outside is a good alternative to sometimes expensive and somewhat difficult lighting set ups in studios. For a studio lighting tutorial, please see this one I made.

Hope that helps a bit!

Thanks so much! Especially for the beginners link for green screening! Although now I have a couple other questions:

1. I bought Chroma-key paint, that I planed on painting to some flats to stand vertical. Any tips, tricks, or thoughts to help?

2. Say we shoot the same location multiple times, yet each time we change the people around, and where they stand. How do I mash it all together, then add in a background, to make it look like a ton of screaming fans? Then I would use that as a background for my real videos!

Anyways thanks so much for your help!! smile

1. For painting flats, make sure they are nice and smooth. Not sure what exactly you have in mind, but the smoother the better for keying, so I'd steer clear of just getting some cheap plywood and painting it. the texture will create lots of tine shadows which makes getting a clean key more difficult.

2. The trick here is to group what extras you do have tightly together. Figure out how much area the can cover, calculate out how many times you will have to replicate them to fill your shot, and then mark out the boundaries of each position. Also, lock the camera off if you can, as it will greatly simplify the process of putting the pieces together if the camera is not moving. In addition, if they aren't tightly packed together, then try to randomly space them out in each position, with small groups here and there, rather than evenly spacing them out. More randomness = more realism.
