That's a 4K camera, and MC 6.5 doesn't do 4K. Do you know if they shot 4K with it? or 1080?
That's a VERY new camera format. And you are running an old version of Avid MC. You MIGHT see if there is a Panasonic AMA plugin for that specific camera. The site only lists ones for DVCPRO HD, AVCIntra and AVCCAM.
