Convenient Creation of Supplemental (VF):

How to convert Subtitle File Formats with easyDCP Player+


Imagine the following situation:

  • The original version (OV) of a SMPTE compliant DCP or IMF package has already been delivered to the cinema or a partner / studio.
  • Now the film must be subtitled. However, the subtitle files are in Interop format only, while the OV is in SMPTE format.
  • The delivery should be a smaller supplemental (VF) containing only one OV compliant subtitle file.

Tip: Subtitle files should always be delivered in the same compliance format as the OV package for maximum compatibility.
AND: The use of Supplementals is very similar for DCPs and IMF packages.


To automatically convert a subtitle file to the format of the OV, proceed as follows:

  1. First load the OV into the easyDCP Player+. Your OV does not have any subtitles yet:
  2. Now simply drop your subtitle file onto the composition:
  3. Your subtitle file will automatically be added to the timeline and to the playlist as "external subtitles" (shown in italics):
  4. The converted subtitle file can now be exported to a directory and, if necessary, further processed with easyDCP Creator+. To do this, press the "e" key, select a destination folder in the export wizard and the menu item "Create supplemental easyDCP project with external subtitles":
  5. Close the export wizard and press "Open Project" to open the project in easyDCP Creator+:
  6. Your project will now be loaded as a VF with the new subtitle file in easyDCP Creator+:
  7. Do not forget to change the composition title according to the Digital Cinema Naming Convention (e.g. "OV" to "VF-1")
  8. Finally, generate a new VF as usual.

Please note:
Creation of Supplementals is only supported in easyDCP Creator+. Please use the newest versions of easyDCP. Previous versions may not include this feature.
