Maximum frame sizes are 2048 × 1080 for 2K DC, and 4096 × 2160 for 4K DC.24 and 48 fps 2K (MXF Interop can be encoded at 25 frame/s but support is not guaranteed).JPEG 2000 is the only accepted compression format. MPEG-2 is no longer compliant with the DCI specification. Each reel contains pictures as MPEG-2 or JPEG 2000 essence, depending on the adopted codec. Picture contents may be stored in one or more reels corresponding to one or more MXF files. The DCP root folder (in the storage medium) contains a number of files, some used to store the image and audio contents, and some other used to organize and manage the whole playlist. 1.5 Packing list file or PKL package key list.While legacy support for Interop DCP is necessary for commercial products, new productions are encouraged to distribute in SMPTE DCP. SMPTE DCP requires significant constraints to ensure success in the field, as shown by ISDCF. SMPTE DCP is similar but not backwards compatible with Interop DCP, resulting in an uphill effort to transition the industry from Interop DCP to SMPTE DCP. In 2009, a specification was published by SMPTE (SMPTE ST 429-2 Digital Cinema Packaging – DCP Constraints) for what is commonly referred to as SMPTE DCP. The original version is called Interop DCP. In practice, there are two versions of composition in use. The encryption used is AES 128-bit in CBC mode. Encryption may optionally be applied to the essence of a track file to protect it from unauthorized use. The Picture Track File essence is compressed using JPEG 2000 and the Audio Track File carries a 24-bit linear PCM uncompressed multichannel WAV file. However, as already noted, it is commonplace in the industry to discuss the title in terms of a DCP, as that is the deliverable to the cinema.

A composition is a complete representation of a title version, while the DCP need not carry a full composition.

The composition, consisting of a Composition Playlist and associated track files, are distributed as a Digital Cinema Package (DCP). Two track files at a minimum must be present in every composition (see SMPTE ST429-2 D-Cinema Packaging – DCP Constraints, or Cinepedia ): a track file carrying picture essence, and a track file carrying audio essence. Track Files carry the essence, which is wrapped using Material eXchange Format (MXF). The composition consists of a Composition Playlist (in XML format) that defines the playback sequence of a set of Track Files. not a complete set of files), a single complete composition, or multiple and complete compositions. The DCP may carry a partial composition (e.g. ) A DCP is a “packing crate” for compositions, a hierarchical file structure that represents a title version. ('You PLAY a composition, You do NOT play a Digital Cinema Package'. However, the industry tends to apply the term to the structure more formally known as the composition. The term was popularized by Digital Cinema Initiatives, LLC in its original recommendation for packaging DC contents. You can easily detect when a device is performing subpar and, and with the spinning disk, you can see is transfer speeds deteriorates over time.A Digital Cinema Package ( DCP) is a collection of digital files used to store and convey digital cinema (DC) audio, image, and data streams.

I have run Blackmagic on USB 2, thumb drives, USB 3, and USB C devices to see if I’m getting my money’s worth.

On an older PC the rates I see are 500 MB/S both read and write, as you would expect. I have tried this on my older mackbooks with SSD and they do scale down as the device is older. On my 2016 PC, I am seeing speeds like 1,000+ MB/s write, and 1100+ MB/S read. Since the “volume” is on your Startup Disk, you will see how fast it drive is. In Blackmagic select the disk image mounted. Mount the volume (if it is not already mounted). Make it big enough for Blackmagic to work with (7+ GB) and name it what you will. Create a disk image (.dmg) using the disk utility specifying file->new image->blank image. I found a workaround that will report the rates of the Startup Disk. When Blackmagic tries to read the Startup Disk, you get the message that the device is not writeable, hence you cannot rate the the transfer rates of the drive. Blackmagic has been updated to adequately report the speed of SSD devices.
