You can stream the footage into the Axio via firewire from the camera. That’s not a problem. I’ve done it and it works fine, looks great! But, the problem arises when you’ve shot multiple P2 cards, and download the cards to a hard drive. Those files on the hard drive don’t stream into the Axio… Only from the camera.
My current workaround is to go thru FCP, use the .mov files into Axio. Until NAB I THINK that’s the only way to do it… get it out of the MXF wrapper and into a file fomat recognized by Axio.
