The
Cineon Converter effect provides a high degree of control over color
conversions of Cineon frames, but in most cases you should convert
the colors in a Cineon file using color management features. (See Working with Cineon footage items.)
To use the Cineon Converter effect, import a Cineon file and
leave it in its default state; After Effects either condenses the
colors to 8 bpc or expands them to 16 bpc, depending on the mode
you work in. You can then apply the Cineon Converter effect to the
file and precisely adjust the colors while interactively viewing
the results in the Composition panel. You can set keyframes or expressions
to adjust for changes in tone over timeāuse keyframe interpolation
and ease handles to precisely match the most irregular lighting
changes. Consider using other Color Correction effects to perform
these corrections instead. (See Color Correction effects.)
The
10 bits of data available in each Cineon channel for each pixel
make it easier to enhance an important range of tones while preserving
overall tonal balance. By carefully specifying the range, you can
create a version of the image that faithfully resembles the original.
Note: Each
computer monitor has unique display characteristics that affect
your perception of color on-screen. For best results when evaluating
tonal balance, use the Info panel in After Effects to see the true
color values of pixels as you move the pointer over them.
- Conversion Type
-
How the Cineon file is converted. Log To Linear converts
an 8-bpc logarithmic non-Cineon layer that you plan to render as
a Cineon sequence. Linear To Log converts a layer containing an
8-bpc linear proxy of a Cineon file into an 8-bpc logarithmic file
so that its display characteristics are consistent with the original
Cineon file. Log To Log detects an 8-bpc or 10-bpc logarithmic Cineon
file when you plan to render it as an 8-bpc logarithmic proxy.
Note: For
compatibility, obsolete versions of each option appear if you open
a project that uses an earlier version of the Cineon Converter effect.
- 10 Bit Black Point
-
The black point (minimum density) for converting a 10-bpc logarithmic
Cineon layer.
- Internal Black Point
-
The black point used for the layer in After Effects.
- 10 Bit White Point
-
The white point (maximum density) for converting a 10-bpc logarithmic
Cineon layer.
- Internal White Point
-
The white point used for the layer in After Effects.
- Gamma
-
Increase or decrease Gamma to lighten or darken midtones,
respectively.
- Highlight Rolloff
-
The rolloff value used to correct bright highlights. If adjusting the
brightest areas makes the rest of the image appear too dark, use
Highlight Rolloff to adjust these bright highlights. If highlights
appear as white blotches, increase Highlight Rolloff until details
are visible. An image with high contrast may require a high rolloff
value.
