Guessing, *only*.....;-)
Since it is a digital signal coming off the camera,
and the codec doesn't come into "play" until you want
to change (or view) footage, it should not matter in
terms of requirements for the raw signal. In terms of
processing footage once it is in the computer
environment, a decently-designed (rarer than one might
think...) DV-codec should be able to handle whatever
the raw signal supplies, though codecs may vary in their
ability to modify the signal gracefully... With the
Canopus codec, I have been able to "push" color and
exposure "unmercifully" with good results (though with
an increase in color noise...). Best: try both ways,
and try to match up and compare the results in post
with your particular codec (but the answer may not
apply to all codecs...).
