Not sure if it will be necessary to "hock the farm", Bill, or at least
not the _entire_ farm.
The PDW-F330 XDCAM HD camcorder lists for $16,800 less lens and
battery and the PDW-F30 deck lists for $9500 although if you need
HD-SDI I/O, you'll instead want the PDW-F70 deck for $15,990. And the
PFD-23 discs are under $30 each, which doesn't impose too much of a
burden even when it's necessary to archive them.
You probably already know this, but the discs are rated for 10,000
read/write/erase cycles and Sony claims an archival life span of 50
years.
Both of the available XDCAM HD camcorders (the PDW-F330 and the
PDW-F350) will do 23.98P, for those times when a filmic look is
required.
I think that the biggest change for most folks will be getting
acclimated to an IT-based, file-based, non-tape workflow. Not to
mention MPEG-4 proxy files, which I understand are time code accurate
to the original footage.
I also think that some purists will be turned-off by XDCAM HD's
long-GOP MPEG-2 (MP@HL - Main Profile at High Level) temporal
encoding, but at least there's four channels of non-compressed PCM
audio to play with. Also, there's a choice of datarates, 18 VBR, 25
CBR, and 35 VBR Mbps.
