I'm wondering what the cheapest option for achieving a split-screen effect with different video clips is. This is on new iMac hardware with the latest version of iMovie '11, as well as QuickTime Pro 7 and iMovie HD '06 installed. Obviously I know Final Cut Express can do this, but I am hoping not to have to pay so much for what should be a simple thing.
Okay, my first bounty. Fun times. Here's what I know: http://imovieplugins.com/ has some very cost-effective one-off effects for iMovie HD. However, it seems quite difficult to install these on 10.6. If anyone has a way to do so, I'd consider that a good answer.
Also, I am aware that the open-source Blender can do this, though the learning curve there is a bit much for me. An easy step-by-step guide for that would suffice if nothing else comes up.
