Supported Color Transform File Formats
In addition to the native CTF format, applications that use Autodesk Color Management can read several
LUT and transform file formats. When imported, these formats are converted to native operators. Autodesk
products that support the export of transforms will export them as CTF files.
Supported formats include:
.lut Autodesk legacy 1D LUT.
.3dl Autodesk legacy 3D LUT.
.cdl ASC color decision list.
ASC .cdl files are loaded as ASC_CDL operators. The style used by the color transform operator is determined
by the SYNCOLOR_DEFAULT_CDL_STYLE environment variable. This can be one of the following values:
v1.2_Fwd, v1.2_Rev, noClampFwd, or noClampRev. If this environment variable is undefined, the default
is v1.2_Fwd. For more information about these styles, see
ASC_CDL (page 1355).
When a .cdl file is applied to the display, a Look switch is added that allows you to toggle the transform on
and off.
.ccc ASC color correction collection.
The first CDL defined in the file is loaded as an ASC_CDL operator. The style is also determined by the
SYNCOLOR_DEFAULT_CDL_STYLE environment variable.
.clf Academy/ ASC Common LUT format.
.csp Cinespace.
.icc, .icm, .pf ICC monitor profile. The PCS-to-monitor-RGB transform defined in the profile is loaded.
.cube Iridas Cube.
.itx Iridas itx.
.look Iridas Look (no mask support).
.m3d, .mga Pandora.
.spi1d Imageworks 1D LUT.
.spi3d Imageworks 3D LUT.
.spimtx Imageworks matrix.
.vf Nuke.
.vlt Panasonic VariCam 3D LUT.
