Basically there are two different options for running easyDCP Player.


1. Real-time-playback using a fast CPU.

Allows for real-time-playback of 2k/4k DCP and IMF-Packages on a standard PC/Mac. Use this option if you have a sufficiently fast CPU. The software codec will work on Mac OS X and Windows 7 and higher.

Minimum system specification:

    • 6-core CPU
    • At least 4 GB of RAM
    • Graphics device with at least 500 MB memory attached to monitor (primary graphics card)
    • Fast hard disk is also recommended


2. Real-time-playback using a Graphics Processing Unit (GPU) as accelerator.

Allows for real-time-playback of 2k/4k DCPs and IMF-Packages *) on a standard PC.
*) limited to lossy with code block size 32x32

This option requires two graphics cards:

1. GPU: Primary device for rendering (OpenGL) to which the display is attached.
2. GPU: Secondary CUDA-enabled device for the JPEG 2000 decompression.

Minimum system specification:

    • 4-core CPU
    • 1x primary graphics device attached to monitor
      • recent NVIDIA GeForce or Quadro series graphics device
      • at least 1 GB VRAM
      • preferably connected with 16 PCIx lanes
    • 1x secondary graphics device not attached to monitor
      • NVIDIA GeForce with at least 500 CUDA cores
      • least 2 GB of VRAM
      • preferably connected with 16 PCIx lanes
    • At least 4 GB RAM
    • Fast harddisk/SSD is also recommended

The GPU-accelerated codec is only available for Windows, not for Mac OS X.


3D Video output options:

For best stereo video output, we recommend a NVIDIA Quadro device with at least 2 GB memory (e.g. Quadro K600). When using Nvidia 3D vision, the display needs to have a refresh rate of at least 120 Hz (e.g. Acer GD245QH). Alternatively, a 3D projector can be connected via Dual-DVI. This does not require a professional Nvidia Quadro card, but can also be achieved with a NVIDIA GeForce card.

Furthermore, a 3D LCD can be connected via HDMI or DVI to play out stereo in side-by-side/top-and-bottom/line-by-line or other interleaved modes.


HD-SDI output option:

easyDCP Player supports Blackmagic Design UltraStudio oder DeckLink series output devices.

When Option HD-SDI "enable subtitling, color processing and scaling" is enabled, decoded images will first be processed by the primary graphics card, before they get sent to the SDI-output device.

This works best, when the primary graphics card is a NVIDIA Quadro card.

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. 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.

easyDCP Creator/Creator+, easyDCP JPEG 2000 Transcoder and easyDCP Publisher are highly optimized for running on multi-processor/multi-core machines. On Windows, it can also use one or more CUDA® enabled graphics devices.

We recommend the following minimal system configuration:

  • Windows PC (Windows 64 bit, Version 7 or higher) or Intel Mac (Mac OS X 64 bit, Version 10.7 or higher)
  • You also need a minimum of 2 GB RAM
  • Installation occupies 200 MB free disc space
  • Fast hard disk is also recommended

For best performance, opt for the following specifications:

  • CPU with 6 or 8 cores
  • 8 GB RAM
  • Fast SSD
  • A CUDA-enabled graphics device for encoding with the following specifications:
    • Compute Capability 2.0 or higher
    • Minimum of 1 GB memory, better 4 GB of memory
    • Preferably connected with 16 PCI Express lanes
    • The more cores, the better
    • E.g. NVIDIA GeForce 980 Ti
