Hi Hans,
I was just trying to make out teh footage on that page. The XDCam and SDI clips looked the same to me.
We are getting a EX1 and I was planning on purchasing a IO HD at somepoint for some superclean keying but am going to have to get by for now with the Mpeg 2 files. It appears to me that you can get very nice results with the Mpeg 2 and the ProRes HQ capture may not be entirely necessary.
The report looks very interesting and would be great to understand more fully.
