Import the fi le Cineon.cin from the Images folder in the Media
folder of the exercise fi les if you'd like to follow along with me. I've
also created a comp using this fi le and have applied the Cineon
Converter effect (Fig. 21.1).
The Nature of
CIN Files
The CIN fi le
format is a still
image format. To
playback frames of CIN
fi les as a movie, they must
be imported as an image
sequence.

effect.
Perhaps, the most important option in this entire effect is the
fi rst property, Conversion Type. Selecting Linear to Log will take
a regular fi le and make it more like a CIN version. Adobe sug-
gests that this is useful for applying to 8-bpc linear proxies so that
they more fully resemble the original CIN fi les. Selecting Log to
Linear will convert a regular (non-Cineon) logarithmic 8-bit fi le
for when you're outputting to a CIN sequence.
The remainder of the settings in this effect are almost like a
mini-Levels adjustment. Note that the 10-Bit Black/White Point
values are set to the correct levels for 10-bit color, by default.
Highlight Rolloff controls what happens to bright highlights.
Increasing this value can smooth out over exposure in the
highlights.
CIN and DPX
CIN fi les have
been an industry
standard for a
while now. However, they
are quickly being replaced
by the DPX fi le format.
The DPX fi le format is
very similar to CIN, but it
also contains additional
metadata-type information
as well.
The Color Profile Effect
The Color Profi le effect is what was used before After Effects
CS3, when a color management system was introduced. These
color management settings are superior and preferable to the
Color Profi le effect. The settings available in this effect are similar
to the ones available in the application's color management. You
