Cineon Converter effect
The Cineon Converter effect provides a high degree of control over color conversions of Cineon frames. In After
Effects, you can convert the color in a Cineon file using controls in the Interpret Footage dialog box or using the
Cineon Converter effect. 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 are
working in. You can then apply the Cineon Converter effect to the file and precisely adjust the colors while interac-
tively viewing the results in the Composition panel. Set keyframes to adjust for changes in tone over time—use
keyframe interpolation and ease handles to precisely match the most irregular lighting changes, or leave the file in
its default state and use the converter.
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.
Adjust the following controls for the Cineon Converter effect:
Conversion Type
Specifies how the Cineon file is converted. Log To Linear converts an 8-bit 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:
Obsolete versions of each option are available for compatibility with projects converted from earlier versions of
After Effects.
10 Bit Black Point

10 Bit White Point
