Let’s make it clear.
Original Version refers to the first version of a film. Supplemental or Versioning File (VF) are all the edited or new versions of the Composition Playlist (CPL), which means the different versions of the film.
The term VF refers exclusively to the relation of a DCP with the Original Version (OV) and in particular to the initial CPL and not the type of packaging that could be completed or partial.
Each Supplemental or Versioning files DCPs can be Completed (they can stand alone and playback without the need of any other files) or Partial (they refer to the reference track of other existing DCP that is needed for the playback). In case of Partial VF, the DCP server will recognize which elements are included in the partial DCP and which ones are on the reference DCP. The refrence can be the OV DCP, or another VF DCP. The screening is always smooth without interruptions.
By using partial VF DCP we can logistics-wise reduce the size of files that need to be transferred. When we send partial VF DCP we also include a projectionist letter to help the projectionist select the right files without any problem. Each film can have one OV DCP and multiple VF. This is also a great advantage of D-Cinema support.
For example, we use VF DCPs if we need to add a new subtitle language in an existing DCP, as long as there are no burnt-in sabtitles in the picture. The size of VF could be small including only the new subtitles. We could also add new credits, such as awards or official selection in film festivals before the opening credits. Edit the final credits correction mistakes, or even change or delete a whole scene of the film, or even add new sound mix or dubbing in other languages.
All this is possible with a little help from Supplemental or Versioning Files (VF) DCPs. Versioning and re-packaging is the future of D-Cinema distribution. We can create and deliver multiple versions of your film at low cost.
We can create DCPs that are compliant with both SMPTE systems and InterOP (IOP). We usually choose SMPTE conformity as it is the new standard with great support from cinema venues. SMPTE DCP packaging allows for an expanded set of features, including higher frame rates, immersive sound, 3D subtitle support, and embedded metadata that makes it easier for the theater operator to understand the technical aspects of the DCP. The SMPTE DCP provides a great foundation for further innovation, automation, cost-saving and presentation quality.
If you wish to screen your film in a Digital Cinema with old equipment (more than 10 years) then you should need interOP conformity. Please inform us in the comments field. If for any reason you need an extra backup copy of your SMPTE DCP in InterOP that could be arranged at an extra cost.
InterOP supports 24fps and 48fps at 2K and 24fps at 4K. If your film has a different framerate we can transcode your film in a supported framerate (picture, sound, and subtitles) at an extra cost. Please choose “conform framerate” in the Services page. InterOP does not support OSUB timed-text encryption.
In our lab, we follow all the recommended guidelines of the Digital Cinema Initiatives LLC. DCI was created in March 2002, and is a joint venture of 5 Hollywood major Studios. DCI's primary purpose is to establish and document voluntary specifications for an open architecture for digital cinema that ensures a high level of technical aspects. The SMPTE DCP provides a great foundation for further innovation, automation, cost-saving, and presentation quality.
Using Cloud Storage, you can easily transfer your film at a low cost in most festivals and cinema venues around the world. It is a reliable and modern solution with a lower cost than mailing the physical media through courier services. You can simultaneously support multiple cinema venues which is not possible with a physical medium. It is also a covid-free solution.
Each DCP is delivered in the form of a verified ZIP file and the link is sent to you by email. This is a safe method to transfer files through the web. We can deliver your film via Aspera, upon request. Select one of our packages.
