Alternatives to DH_Box for split-screening?

[lovetrumpsfear]

Hi all,

I'm working on a personal project, which uses a lot of boxing/split-screening, to reposition clips within the frame.

I was inspired partially by Shadowplay's title sequence for Up In The Air:

I know they probably did theirs in AE, but all I have is FCS2, so I was wondering if there is a good/cheap way to achieve a similar look? I found DH_Box by Digital Heaven, but it's a little wonky to get certain slides/zooms to work.

Any suggestions for a (very) budget-conscious filmmaker?

Thanks much!
Paul
