Converts between common ASC Color Decision List (CDL) formats

Project description

PyPI VersionBuild StatusCoverage StatusCode Health

Converts between common ASC CDL formats. The American Society of Cinematographers Color Decision List (ASC CDL, or CDL for short) is a schema to simplify the process of interchanging color data between various programs and facilities.

The ASC has defined schemas for including the 10 basic numbers in 5 different formats:

  • Avid Log Exchange (ALE)
  • Film Log EDL Exchange (FLEx)
  • XML Color Correction (cc)
  • XML Color Correction Collection (ccc)

Unofficial Formats:

  • OCIOCDLTransform, a Foundry Nuke node
  • Space separated CDL, a Rhythm & Hues internal cdl format

It is the purpose of CDL Convert to convert ASC CDL information between these basic formats to further facilitate the ease of exchange of color data within the Film and TV industries.

CDL Convert is not associated with the American Society of Cinematographers


Currently we support converting from:

  • ALE
  • CC
  • FLEx
  • CDL


  • CC
  • Space Separated CDL

With support for both from and to expanding in the future.


Installing is as simple as using pip:

$ pip install cdl_convert

If you don’t want to bother with a pip style install, you can alternatively grab cdl_convert/, As this file is the script and all the functions and classes needed.


If you just want to convert to a .cc XML file, the only required argument is an input file, like so:

$ cdl_convert ./di_v001.flex

You can override the default .cc output, or provide multiple outputs with the -o flag.

$ cdl_convert ./di_v001.flex -o cc,cdl

Full help is available with --help


CDL Convert is written for Python 2.6 through 3.4. Code is written for strict PEP 8 compliance, with all code being checked on push through Docstrings follow Google code standards.

Development uses Git Flow model.
