Does anyone know of any software that enables you to monitor in HD the output from an HD camera (using firewire), that runs on a mac? I'm not looking to record onto the laptop, I just need a way to check focus/composition.

Thanks
Greg

HD Monitor Pro is software for the HVX200. It recognizes the Canon XH-A1 but doesn't work with the A1.

Also Monitor Magic:

Aren't some people just using Final Cut Pro on a laptop?

Thanks so much James, Monitor Magic was exactly what I was looking for, at a price that I can afford.
