Maybe early days but I was wondering if you utilised the PDWU1 to transfer XDHD 4:2:2 material how would FCP 6 deal with transcoding those files to ProRes? and what sort of processing time would this take?

Would there be any advantage from moving from LGOP format to ProRes?

The PDW-U1 is really just a drive, not a deck. This is fine when you edit native XDCAM video, since all you need to do in that workflow is transfer the files to your editing machine. If you want to transcode video files into ProRes422, and edit with the ProRes files, you will need to use the camera or a deck to play the video, and ingest it into the editing system via the HD-SDI connections through some sort of video card, like a Kona or Black Magic card. But doing that will take away all of the "cool" features of the XDCAM workflow, like file-based editing.

Pro res codec allows realtime dissolves of XDCAM on the timeline, so faster editing. Saw it @ NAB, some great advantages to this codec.

In my FCP system I get realtime dissolves natively. Just using the easy setup for XDCAM HD.

Tim, it's a bit early to tell, but using the current incarnation of XDCAM HD, you would use XDCAM Transfer to bring in the full res material you need. That places QT files on your drive. You can import those files into the media bin(assuming you didn't invoke XDCAM Transfer from within FCP in which case that's where they'll automatically end up). At that point, you can drop them into whatever timeline property you wish. Of course, it will have to render the files at that point. You're not locked into editing the files in their native codec. So I believe you could set the timeline property to ProRes and 'get 'er done'.
