Beyond DCI – The Need for New D-Cinema Standards

The DCI spec was published seven years ago, designed to lead to the same kind of uniformity in equipment standards as that of 35 mm film. Although it has been a great boon for D-cinema, technological advances are moving so quickly that it is time to revisit these standards.

Filmmakers, exhibitors and viewers are demanding more lifelike 3D movies with fewer artifacts, less motion blur and more comfortable viewing. Inevitably, this means films need to be produced, packaged and exhibited at higher frame rates than they are now. Currently, digitally projected films run at 24 fps, but this is set to change with upcoming releases, most notably The Hobbit, scheduled for release in December, which is being shot in 3D at 48 fps, and the Avatar sequels, which we’ve heard that James Cameron plans to shoot at 60 fps.

Black Screen Alert~! InterOp Losing Life Support

Remember “Paradigm Shift”? Of course not. Writers have been banned from using that overworked phrase for another 20 years. The same will soon happen with the misused terms “Perfect Storm” and “begs the question”. Notwithstanding, we need a way to describe the potential for Reality-laced Hyperbolic Activity that is coming to Digital Cinema screens everywhere.

Potential Points of Failure Quotient = 10.95. Hyperbole Quotient…OK, InterOp will be around a long time for legacy, but don’t expect it to continue for everything else.

Does that describe it? OK, let’s see how it can happen (and we’ll keep math and the SMPTE Police out of this.)

Certificate Authorities and DCinema

This weeks news brings up a sore subject: Trust.

In DCinema, this means Trusted Device Lists (TDL) and Certificate Authorities as specified in the SMPTE/ISO and DCI documents.

In the outside world, the foundation is also a group of companies who issue certificates that bring different levels of trust to different websites or those who access the websites. These companies are the CAs or Certificate Authorities. Last year, one was found to have been hacked.

3Questions: OpenDCP – Now with GUI

3 Questions with OpenDCP creatorThe dream of creating DCPs for local commercials and film festivals by artists using simple yet affordable tools just took a monumental step forward with the latest advance of OpenDCP.

Created by a theater owner and long-time computer engineer, this tool uses a combination of Open Source tools to take a finished ‘movie’ and turn it into a package that can be played by a digital projection media player and projector. And, it is free.1

Iosono Surround Sound – a perfect companion to 3D releases?

Developed by Germany’s Fraunhofer Institute, Iosono Surround Sound is a new encoding and delivery format for digital cinema based on research into wave field synthesis.

Since post facilities need to use existing rerecording consoles that feature limited output busses and panning, the Iosono format currently uses a Nuendo add-on which accepts up to 32 individual sources or groups of sources that can be level-balanced and panned anywhere within a horizontal soundfield using a customised user interface. The resultant 32 data tracks carry a representation of the encoded sound sources to the final venue, and currently are carried on the last eight tracks of the DCI Specification, using 4:1 HD-AAC lossless compression.

DCI Compliance – Then There Were Three [Updated]

The DCIMovies website now lists 3 NEC, 2 Chrisite, and 3 Barco projectors as having passed the Compliance Test Plan detailed procedures. All 3 manufacturers are utilizing the same version of the Texas Instruments (TI) Enigma board and what appears to be similar versions of software. Details are on the linked site above.

Christie Press Release         Barco Press Release            NEC Press Release


Christie has just announced that their CP 2220 Series 2 projector has passed muster at CineCert for DCI Compliance. The sentence that says that they are the first has me in an infinite loop, which prevents me from reading any more. There is probably some nuance that says that they did something that Barco didn’t do, but who knows…the rest of the press release just seems so release-y after that.
