The folder...does it have CONTENTS, and then CLIP, VIDEO, AUDIO, PROXY and a couple other folders? If so, it's P2. And P2 can either be DVCPRO HD or AVCIntra. DVCPRO HD only comes in as DVCRO HD...you cannot convert it to ProRes. But DVCPRO HD is a very good codec, easy to edit...and when you import it you are bringing the footage in full quality...it's re-wrapping the original format (MXF) into Quicktime.
