This chapter explains other DCP related topics, such as how to adapt
the rating agencies, how to merge DCPs or how to deal with keys and
certificates.
6.1 Color Space Conversions
According to the DCI specification a DCP or DCDM should be convert-
ed and saved in the X’Y’Z’ color space. There are several user interface
items available to configure the color space conversion to X’Y’Z’ in
CLIPSTER.
The most important concept about a color space conversion is, that you
should know the source material that you want to finalize. The proper-
ties of clips added to the bin and used in the timeline (context menu of
bin clip » Properties…) must reflect these, i.e. they have to match the
properties of the material on the storage.
Usually this will be sufficient when performing a play-out or finalizing
to another color space: The color space of each clip in the timeline (set
via the bin clip properties) will be evaluated separately and an automat-
ic color space conversion will be applied when the set output color
space differs.
However, when finalizing to JPEG2000 or DC MXF, another setting has
to be observed as well. This setting (the Color Space Interpretation
setting) can be found under the JPEG2000 encoding parameters (see
section “JPEG2000 Options” on page 6-4). When finalizing to
JPEG2000 or DC MXF, it describes the color profile of the source mate-
rial in RGB, and you have to set it to the profile that matches your video
material in the timeline (see also section “JPEG2000 Options” on
page 6-4).
