Introduction

cdl_convert 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)
  • CMX EDL
  • XML Color Correction (cc)
  • XML Color Correction Collection (ccc)
  • XML Color Decision List (cdl)

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 supports parsing ALE, FLEx, CC, CCC, CDL and RCDL. We can write out CC, CCC, CDL and RCDL.

cdl_convert is not associated with the American Society of Cinematographers

Changelog

New in version 0.9.2:

  • Fixed a bug where ALE's with blank lines would not convert correctly.
  • Fixed a bug that was preventing cdl_convert from being correctly installed in Python 2.6
  • Fixed continuous integration testing.
  • No longer officially supporting Python 3.2, as I've had to remove it from our CI builds. It should still work just fine though, but we won't be running CI against it.

New in version 0.9:

  • Added ability to parse CMX EDLs
  • Fixed a script bug where a collection format containing color decisions will not have those color decisions exported as individual color corrections.
  • Fixed a bug where we weren't reading line endings correctly in certain situations.
  • Added a cdl_convert.py stub file to the package root level, which will allow running of the cdl_convert script without installation. Due to relative imports in the python code, it was no longer possible to call cdl_convert/cdl_convert.py directly.
  • The script, when run directly from cdl_convert.py, will now write errors to stderror correctly, and exit with a status of 1.

New in version 0.8:

  • Added --single flag. When provided with an output collection format, each color correction in the input will be exported to it's own collection.
  • Giving a :class:`ColorCorrection` a non-duplicate ID now works unless the --halt flag is given. This means that incoming collections that contain duplicate IDs will not fail out.

New in version 0.7.1:

  • Fixed bug where ALE's without 'Scan Filename' fields could not parse correctly.

New in version 0.7:

The biggest change in 0.7 is the addition of collection format support. .ccc, Color Correction Collections, can now be parsed and written. .cdl, Color Decision Lists, can now be parsed and written. .ale and .flex files now return a collection.
