Note: The preparing and copying of DCPs to hard drives is not a component of the easyDCP programs. We provide information about our customer’s experience from their practice
Quality and kind of hard disk are not important but it is recommended to use a powerful interface, e.g. eSATA or USB 3.0. Commonly, carriers from the CruDataPort series are used.
The file-systeme is very important. According to DCI specification EXT2 or EXT3 is required. These file systems are supported natively by LINUX.
Third party drivers/emulations are available for MAC and Windows, but we know from some customers that they had problems with the Windows drivers. It is recommended to install a LINUX system either on a remote or virtual system and have it share the mounted DCP via SAMBA.
The time it takes to copy a DCP onto a mobile hard-drive depends on the DCPs size and on the bandwidth. A 90-minute DCP can take up to 200 GB.
It is highly recommend to verify the DCPs integrity. To do that, you can start the DCP validation (included in easyDCP Creator+ and easyDCP Player+) and run a Hash-check (e.g. with MD5) of the DCP before copying to the hard disc. After copying run the Hash-check again. The results of the hash-check must be identical otherwise the DCP may crash.
This extra work is in no relation to later exchange of the DCP in the cinema.
Copying needs to be done independently from the easyDCP application, e.g. with Finder or Windows Explorer. Customers with macOS like to use the program DCP Transfer.
Also professional mass-duplication software is available and convinient for larger copy batch jobs.
Additional hint: Using of Digital Cinema Naming Convention is higly recommend to ease the workflow in the cinema server. Create correct syntax of Digital Cinema Naming Convention is embedded in easyDCP applications.
JPEG 2000 files generated with the easyDCP Creator meet the required requirements.
You can also import pre-generated JPEG 2000 files. Make sure that the input format "Option", the entry "JPEG 2000 Re-encoding" is disabled. In this case, easyDCP Creator does not check if these files are compatible with current standards. The software merely copies the files to the DCP.
This may eventually lead to a rejection of the DCP by certain playback devices / digital cinema servers. In such cases, we recommend checking the entire DCP with the DCP validation function of easyDCP Player + or easyDCP Creator +.
Currently, we are not aware of any problems with DCPs that are generated by easyDCP Creator.
