Iraq in Fragments was shot in DV throughout to my knowledge and does not
mix SD and HD. From your question I thought you were mixing SD and HD
am I right? I inferred, probably incorrectly, that you intended to
begin shooting with PD150 and then get a HD camera at a later point in
time and then mix the footage by up-rezzing the PD150 footage. If you
intend to go that route the well shot SD footage will look, frankly,
crap compared to well shot HD(V).

PD150s in 16x9 mode have been unacceptable for SD broadcast for some
years now. Even for SD broadcast a PD150 must at least have been fitted
with an anamorphic adaptor or shot in 4x3 and ARC-ed to 14x9 (then
transmitted as 16x9). The mere opinion of broadcast engineers in the UK
is that the PD150 16x9 mode produces unacceptably poor quality images.
The vast majority of ENG and actuality based programming is done using
Sony Z1s and DSR-570 and their replacements. The trusty PD150 has had
its day for serious work...

Of course it is entirely up to you and your client what you see fit to
use on a project and I wish you the best of luck with how it goes. In
my mere opinion if I was shooting a doc now and wanted it to stand the
test of time I wouldn't be shooting in SD at all let alone a bottom rung
quality version of SD.

I suggested the Canon HDV cameras as I thought you had budget
constraints having chosen to shoot with the PD150.. The Canon cameras
are the best (IMO) of the current crop of HDV cameras. Frankly you have
to purchase the F350 XDCAM HD variant and put a bloody good lens on it
to get an appreciably better image than the Canon HDV cameras.
