Re: KONA FCP WORKFLOW- General questions
by Bob Zelin on Feb 21, 2007 at 11:21:07 pm

yes, yes, yes. First, I have NEVER heard of ANY broadcaster in the US that will even accept a 1080p delivery. All Sony HD VTRs (and I don't know the SRW series) will only record 1080i, not 1080p. DVCProHD is a codec, widely used by everyone, except the most hi end HD delivery products (that demand uncompressed HD). A DVCProHD compression job will record back thru the Kona right onto the Sony HD VTR at 1080i, with NO PROBLEMS.

When you see people saying "this guy is full of crap, you must use uncompressed HD" - remember this. 95% of the broadcasters in the US use AVID Adrenaline HD systems, and these systems DO NOT use uncompressed HD - they use the DNxHD codec, which is similar to DVCProHD. The top DNxHD resolution is called DNxHD220, which is similar to DVCProHD. AND CBS NETWORK uses the AVID Unity ISIS server, which can only operate at the lower compressed resolution of DNxHD145, so dont' let anyone snow you about uncompressed HD.

Uncompressed HD is teriffic, but most people simply don't use it, for cost
and storage reasons. This includes AVID and AVID users. As for 1080p delivery - no TV station that I know of will accept this as a delivery format, and if you rent a Sony HDW-M2000 or HDW-F500 to lay off your job to, it's going to be 1080i, not 1080p.
