  1. '''
  2. FCP XML to Nuke
  3. v1.51 -
  4.         Added lock_range true
  5. v1.5 -
  6.         Added render format selection, to allow the user to set what format the created write nodes are set to. Currently the choices are Prores4444, EXR, JPG (0.9 422), and DPX.
  7.         Rendering from Nuke in Prores 422HQ is not reccomended due to color shifts introduced by Nuke's YUV->RGB color transform. When Prores4444 is selected, the framerate is set to the clip framerate for the current clip.
  8. v1.4 -
  9.         Fixed a bug handling XMLs with multiple sequences.
  10. v1.3 -
  11.     Made support for Premiere FCPXML format more robust. Premiere FCP XML stores all sequences in the project, whereas
  12. Final Cut Pro's XML format stores only a single sequence. I added a box that lets you choose what sequence
  13. of the Premiere XML file to process, and it should work more reliably now.
  14.     Added support for transfer of linear TimeRemaps, Translates, Scales, and Rotates into Nuke.
  15.     Also transfers framerate for each clip, and many other improvements.
  16. v1.0 - Initial release.
  17.  
  18. This script takes a Final Cut XML file with a single flattened video track, and builds Nuke scripts for each clip in the timeline.
  19. It is intended as a simple way to automate workflows between FCP/Premiere and Nuke.
  20. It creates a Nuke script with global first and last frame set, a frameRange node with the proper framerange, and a Write node
  21. set to the output path and the render format that you specify.
  22. There is an option for creating subdirectories for every Nuke script created. Handles are also an option.
  23. It can parse reel number and clip number from Red and Alexa footage, or can use the clip filename as the base naming for the output files.
  24.  
  25. This script was somewhat inspired by compflows.blogspot.com, but has been written from scratch and is a bit more flexible (although it only goes from XML->NukeScripts and not from renders back to an XML at the moment).
  26. This has only been tested on OSX, but in theory should be cross-platform compatible. Comments and suggestions are welcome!
  27.  
  28. # The menu.py example entry below adds this script in a folder called "Scripts" in your toolbar.
  29. import fcpxml_to_nuke
  30. nuke.toolbar('Nodes').addMenu('Scripts').addCommand('FCP XML to Nuke', 'fcpxml_to_nuke.process_xml()')
