what parameters can be addressed in saving to dpx format via
nconvert? how is this done? what is the syntax? is there documentation
on this someone could point me to?

Which parameters for dpx??

not sure what to look for for dpx. i mainly know there are
various parameters for different formats, like amount of
compression for jpg, and that in xnview there are at least
a couple of things when saving a file to dpx; something
pertaining to lut and 8 or 10 bit i think.

how would i address these and what other things might i be
able to set for a save to dpx format?

thanks,

For DPX, there is no other parameters

thanks for the reply. are there any plans to support any of these
features of dpx which i got from the graphicsmagick site? would
be much preferable to continue with nconvert rather than having
to jump over to graphicsmagick for dpx conversions. i prefer
nconvert for the native cr2 support, to just mention one thing.
very nice (and thanks so much for the recent fixes)!

also, with all of the various parameters listed below for dpx, which
does xnview default to?

thanks again,
