What is a DCP (Digital Cinema Package) and how does it differ from traditional film?
Simply put, a DCP is as close to a strip of film as it gets in the digital world. In a DCP, a filmmaker’s video track is encoded frame by frame in the robust JPEG-2000 format. This format allows each element of a film to be stored separately in a folder. A Digital Cinema Server utilizes this folder along with other elements to properly project every element of your motion picture on the big screen.
Why doesn’t my DCP hard drive show up on my computer’s desktop?
Digital Cinema Servers run a variant of Linux OS and as such all DCP hard drives should be formatted Linux EXT3. If you wanted to view the contents of these hard drives, you will need to open the drive on a computer running Linux OS or purchase third party drivers.
Can I watch my DCP on my computer?
Several third party applications exist that will allow you to view a DCP on your computer, but most of them are costly and can’t be used to effectively check the quality of your film. The best way to view your film is in a certified Digital Cinema.
Do I need to convert my film to 24 fps before creating a DCP?
The short answer is most likely. While newer Digital Cinema servers are capable of playing back films at many different frame rates, the vast majority of servers can only play content reliably at 24 fps. We advise clients regularly on the best solutions for converting the frame rate of their films and will be happy to assist you too.
If I wanted to convert my film into a DCP, what is the best format to submit to INDO DCP?
For the highest quality DCP, we recommend asking your online editor and/or color correction facility to output a DPX or TIFF image sequence onto a hard drive. This is what is known as a DCDM.
What is a KDM (Key Delivery Message)?
When DCPs are encrypted, they require a special key to open them and this key is encoded into a KDM. KDMs allow you to specify what facilities can and cannot view your film and can be sent out at your discretion.
What is a CRU drive?
A CRU drive is a SATA-II hard drive enclosed in a DX-115 hard drive carriage. Originally designed for the military, the DX-115 is now used by the film industry in D-Cinema for its proven reliability and sturdiness. Certain film festivals and facilities require this drive for DCP delivery and it is highly recommended for feature films formatted in 4K, 3D or High Frame Rates.
What is X’Y’Z’?
X’Y’Z’ is the color space utilized by Digital Cinema to process color data in all of its images. You’ve probably heard of RGB and CMYK. These variables represent the way that color is processed in a digital environment. In this case, X’Y’Z’ works very much like a Lookup Table when filming digitally. Incoming picture data is compressed into a more finite range of colors allowing the video compression to operate more efficiently and record the image with far greater detail. Viewed raw, the colors appear muted and warped, but when processed correctly the colors appear as intended. It is not necessary to deliver your source material in this color space.
Can you turn my DVD or Blu-Ray into a DCP?
Yes, but we highly recommend avoiding this if possible. To see the full benefits of formatting your film as a DCP, we need to start out with the highest quality source material.
I have a Dolby Pro Logic mix. Is this acceptable?
We will not decode or demux any audio mix and require all sound to be delivered as discrete channels of audio. Please arrange for your sound mixer to generate an appropriate mix for a theatrical environment.
I have read about a lot of free tools for DCP creation. Can’t I just make a DCP myself?
Pardon us for not recusing ourselves, but the plain fact of the matter is that the vast majority of these tools simply do not work. From sound dropouts to low image quality to DCPs that simply will not open, the list of woes encountered by film festival managers and theater owners with these tools are consistent and pervasive. More importantly, what may work on one server will very often not work on another using such tools.
At INDO DCP we pride ourselves in delivering the highest quality products in a timely fashion that are guaranteed to work!
