Thanks, Arnie.
I will try the way as you told me, too.

You mean on After Effects, or Final Cut Pro?
Yah,,I’m sure green screen is the best way to do this. but Thank you, Shane:)

Thanks.
Yes, I meant green screen. what I wanted to do is both are shots at same location, and both shots are exactly same framing. one is a guy standing in left side of frame, and other one is a guy standing in right side, and 2 guys( a same guy) are shown in a frame as a final image.
this seems too much task for me..
