  • Special Rules for the International Feature Film Award
    94th ACADEMY AWARDS RULE THIRTEEN SPECIAL RULES FOR THE INTERNATIONAL FEATURE FILM AWARD The unprecedented coronavirus/COVID-19 global pandemic mandated the closure of commercial motion picture theaters worldwide. Country-selected films that had a previously planned theatrical release but are initially made available through a reputable commercial streaming distribution service or video on demand may qualify for Awards consideration in the International Feature Film category for the 94th Academy Awards under these provisions: Provide to the Academy documentation (original document(s) and an English translation) of government-mandated theater/cinema closure dates, previously planned theatrical release and streaming distribution or video on demand agreements; Make the selected film available on the secure Academy Screening Room member site within 60 days of the film being officially selected; Meet all other eligibility requirements. When theaters reopen in accordance with national and local specified guidelines and criteria, and on a date to be determined by the Academy, this exemption to the rules will no longer apply. All films released thereafter will be expected to comply with the standard International Feature Film category theatrical qualifying requirements. In order for films to more easily meet theatrical exhibition requirements, the Academy will allow films to qualify outside the country of origin, provided the film is theatrically exhibited outside of the United States and its territories for at least seven consecutive days in a commercial motion picture theater for paid admission. The International Feature Executive Committee will evaluate all matters of rules and eligibility. Film festivals have been impacted by the coronavirus/COVID-19 pandemic. Participation in an impacted festival’s online/virtual platform will not affect a film’s eligibility for Awards consideration provided the festival has a transactional pay wall or password-protected entry.

  • EIDR in Digital Cinema Using EIDR in Digital Cinema
    Using EIDR in Digital Cinema Using EIDR in Digital Cinema Interim Technical Note – Version 0.5 (11-Apr-2016) 1. Scope This Technical Note specifies best practices for the use of Entertainment ID Registry (EIDR) identifiers in the theatrical exhibition of Digital Cinema. Associating a unique, persistent, non-proprietary identifier with theatrical content (including but not restricted to Features and Trailers), will enable the integration of disparate systems and automate existing manual processes. The scope of this document is restricted to the portion of the digital distribution chain that begins with SMPTE Digital Cinema Packages (DCPs), and encompasses other downstream systems used by theatrical distributors. Explicitly out-of-scope are post-production workflows, where the use of EIDR identifiers is already well- established and documented elsewhere. Also excluded are so-called “Interop” DCPs. This is a legacy format that is being phased out in favor of SMPTE DCPs. Note: The Composition Playlist discussed in this document should not be confused with a similar structure found within the Interoperable Mastering Format (an emerging post-production standard): despite superficial similarities, they have separate SMPTE specifications. 2. Overview DCPs are the means of distributing cinematic content to theatrical exhibitors who have deployed digital projection systems. Work to develop a standard architecture was initiated early in the 2000’s by Digital Cinema Initiatives, LLC (a joint venture of several major studios), and the architecture is embodied in a series of standards developed by SMPTE. DCPs are the replacement for reels of 35mm film, and (as of 2010) are the only mechanism for theatrical distribution.

  • Cinema Distribution in the Age of Digital Projection
    CINEMA DISTRIBUTION IN THE AGE OF DIGITAL PROJECTION CHARLOTTE CROFTS It has become almost axiomatic to state that the transition to digital technologies represents a momentous period of change for the cinema. As Angelo D’Alessio of the European Digital Cinema Form suggests, “the Cinema industry is confronting unparalleled levels of complexity, dynamic change and pressure to innovate.” But it is the final move to digital distribution that signals a complete paradigm shift for the industry: “the recent introduction of digital technologies into the final links in the production and distribution chain is, in fact, a ‘tipping point’ that fundamentally changes the industry’s economics and practices” (“Digital Dilemma” 8). The rollout of digital distribution is contingent upon the wider infrastructure, the adoption of digital projection by the cinema operators, and the provision of digital content, so there is some unavoidable cross-over into the areas of cinema exhibition and production in the following discussion of what is a complex and rapidly shifting ecology of interests at stake in the conversion to digital cinema. As Marcus Weiss noted back in 1999 on the eve of the first wave of digital projection, “for these changes to take place, they must be accepted by the creative community, the production studios, the distributors, the exhibitors and finally the public”. For as long as cinema has been a business, there have been close connections between production, exhibition and distribution and this is ever more true at this time of unparalleled technological change. As a result, it is often difficult to separate these strands of the industry.

  • Digital Cinema Technologies from the Archive's Perspective
    Digital Cinema Technologies from the Archive’s Perspective by Arne Nowak, Dep. Moving Picture Technologies1 Fraunhofer Institute for Integrated Circuits, Germany This is a revised version of an article which first appeared in AMIA Tech Review Volume 2, October 20102 1 Introduction During the last few years digital technologies have gained much ground in production, editing, post‐ production and exhibition of cinematographic work. This fundamental change of technologies also has had a large impact on archives. On the one hand archives have very successfully implemented digital restoration and digital distribution of films on the internet or via DVDs, as well as to digital cinemas. On the other hand archives will have to adapt and change existing procedures or introduce new processes because they will be confronted with digital material for deposit that is not bound to a carrier medium, as is the case with film or video cassettes. Instead the images and sound will come to the archives in the form of digital computer files. Digital cinema has evolved over the last few years, and even though various alternative systems and solutions are used in different parts of the world, most commercial productions in North America and Europe use a system that has its origin in the Digital Cinema Initiatives3 (DCI). DCI was a joint venture of six major American film production companies which together worked out an open specification for a digital cinema system. Many parts of this specification have been adopted by SMPTE and also transformed into standards by the international standardization organization ISO. This article is intended to give a basic introduction to the technologies and processes that are associated with the DCI / SMPTE digital cinema system.
