easyDCP Creator creates SMPTE- or Interop- compliant DCPs as well as SMPTE-compliant IMF packages.
JPEG 2000 files generated with easyDCP Creator meet all necessary requirements.
However, one has to consider that, importing pre-generated JPEG2000 files as input format and disabling the "JPEG2000 Re-encoding" option, easyDCP Creator does not check if these files are compliant to the current specifications and standards. The software merely copies the files into the DCP. This may end in a DCP being rejected by certain playback devices/digital cinema servers.
Furthermore, not all server systems in the market are able to playback all types of content and may behave differently.
Currently we are not aware of any problems regarding DCPs generated with easyDCP Creator.
