Duplication / Twins -The Possibilities of Compositing?
I got a funny idea of “seeing double,” of making two of me on the screen at the same time. So many movies these days do it, I thought why not I, I have final cut pro, so can I.
Unfortuantly after my trail I found I can’t, or a least I have not yet learned how that would be done in Final Cut Pro.
What I did:
Took out my camera, filmed one shot of me turning one way and giving the air a high five, then I moved to the other spot and gave the other direction a high five. So my goal is to make it look like there are two identical versions of me giving each other high fives.But it didn’t work:
I thought all I needed for this to work was getting the two shots to match, thus they had to be still. Well the background matched, no problem there.but the two versions of me in frame are ghosts, most likely their opacity is maxed out at 50% (I can see the background through and behind me.), so I have two ghost giving each other high fives.
What I did:
In the timeline, I stacked two clips in Final Cut Pro 5 above another, then went to composite and selected “add.” (Later I tried them all, but I was still ghostly.) Nothing worked.Is there a way to do this in final cut pro, or even motion? Is it going to involve green screens? Is there a cheep way to get the desired results? Am I that far off?
Thank YOu for you future time and assistance,

Don’t do that.
Stack them on top of each other, just like you did. Now CROP each one…load it into the viewer and select the MOTION tab, and use the CROP tools near the bottom.

If the tripod was locked off, lens not touched, camera not moved between takes, then the shots / backgrounds *might* line up nice and clean as you crop … hard to get the hands to meet like this though!

or use a garbage mask. It’s super easy. I just did a short 15 minute film using garbage masks, and it looked great. However, if your lighting was not the same, you might get a bit of a headache color correcting one to look like the other. Also, try feathering the mask a bit for a sure clean shot.

Alexander,
What exactly do you mean by a garbage mask? Would you mind detailing the process please?
Another Question:
How can I use this same technique for moving shots? Is it even worth trying (I.E. if I do all the work, will it even look good?)
Thanks guys,

Look in your EFFECTS tab under MATTE. There you will see 4-POINT GARBAGE MATTE and 8-POINT GARBAGE MATTE. When you apply those, you can adjust the shape of the matte…in a limited way. You have to play with it. And for moving shots, you need to key frame it and make adjustments on each frame. VERY time consuming.
You should look into Kevin Monahan’s book Motion Graphics for Final Cut Pro…Amazon.com

For starters, you’d want to shoot at least ONE of the versions of you on green-screen. This would totally negate the ghosting you were talking about.

(he’s talking about the moving shots only, i assume, because if you have a rock-steady tripod, you’re all good.)
Also, If your characters overlap, you might be in for some rotoscoping in AE or something of that nature.
