Managing Digital Formats: Choosing the Right Lens

Photo of 3 lenses on Christie Film Projector
35mm Christie Projector equipped with motorized 3 lenses system.

In the d-cinema world of 2 K and 4 K, every format is defined by a specific resolution. Therefore, when the digital image is formed on the chips inside each projector, it takes a greater or lesser size. In 1.85, the image occupies almost the entire surface of the chips:

2K photo with pixel explanation
2 K: 2048 x1080 = 2.21 million pixels. – 1.85: 1998 X 1080 = 2,150,000 pixels

2.39 in Cinemascope, as the resolution is less in the vertical direction (2048 X 858), the image is “letterboxed” which means black bands are present on the top and bottom of the screen.)

Scope Image with dimentions
2.39 Cinemascope image (red) fits into the format of the DMD (blue frame) is 1.89.

During projection, so that the image fits perfectly on the screen in any format, the installer must select the right lens. For each projector, there is a wide range of optics. To determine the appropriate lens, the technician takes into account the properties of the room to be equipped as follows:

– The base of the screen. Example: 20 meters.

– The distance between the projector and the screen.) Example: 35 meters.)

Projector

Divide the projection distance (35 meters) from the bottom of the screen (20 meters) with a result of 1.75.

From this calculation, the installer can select the target whose range corresponds to that number:

Image showing chip size in projector

1.2 refers to the size of the chips installed in the projector. Different series of projectors have different sizes of chips.

The numbers “1.6 – 2.35: 1” means that this is a zoom lens, meaning that the zoom lens has a range of ratios, and thus it has the ability to cover different screen perspectives. In cases where a wrong lens is installed, the image may extend beyond the screen or, on the contrary, it will be surrounded by black bars. This is due to the zoom range that does not match the proportions of the room to be equipped.

Lens showing zoom lens ratio numbers

For the lenses of d-cinema, the numbers of the lens ratio must be applied. 

To managing format changes, we must necessarily take into account the screen size of the room. Manice details in the two articles below for the technical solutions:)

Appeals Judgement in DCN VPF…

The case is, in one sense, rather straight forward and is well described in the attached press release regarding the Federal appeals court finding. A full reading of the court document is interesting as well since it describes more of the story as the appeals judge had to review the entire proceeding in only a few pages. The case law doesn’t sound that much different than what one would expect from most ‘Western” countries. The official court link to this case can be found at:

http://www.austlii.edu.au/au/cases/cth/FCAFC/2011/166.html

On the other hand, as the industry turns the corner toward full implementation of digital around the world, this still leaves a mess of a negotiation for settlement by OmniLab with digitAll [not DCN – correction from earlier draft–Ed], then a return to the table of the independent exhibitors to strike a deal with the studios still offering VPF deals. So, there is still more to the story to pay attention to.

AES Attacks DCinema Sound

To affect the latter, the AES has a new technical committee forming around audio reproduction for Digital Cinema. Television is also stuck onto the title, though either outlet is a large enough mandate.

The challenge of audio in the modern cinema comes from many angles. One is keeping it sane safe and listenable during and before movies. On the other hand, there is a different experience potential and expectation for sports and live performance. Since they are part of the magic of alternative content – the miracle that is supposed to compensate for the additional 4X digital costs over film equipment – handling customer increased audio expectations will need to be addressed.

Editorially, we’ll let this article – and press release from the AES – begin a series of AudioRants that will bring out the issues, problems and potential solutions. As vice-chair of the committee Dr. Toole has said, “It’s not rocket science, but it is science.”

Formative AES Technical Committee on Sound for Digital Cinema & TV

December 8th, 2011 Posted in Newsnewsletter

New York, NY — The Audio Engineering Society has formed a provisional committee to review audio reproduction for Digital Cinema and Television. Spearheaded by Brian McCarty, Managing Director, Coral Sea Studios (Australia), the new AES Technical Committee on Sound for Digital Cinema & Television, AESTC-SDCTV is planning a meeting in Los Angeles in early 2012. To participate in this event or to join the AESTC-SDCTV Committee contact: Brian McCarty (http://www.aes.org/technical/sdctv/).

“Our mission is to identify a consistent approach to controlling perceived loudness and frequency response from installation to installation, and from position to position within Digital Cinema installations worldwide,” McCarty said. “And, for this to be adopted as the formal reference for all contemporary dubbing stage recording and mixing activities, and ultimately as the unified method for film reproduction at home.”

Originally addressed at AES Technical Committee meetings in London in 2010, the initiative was inspired by the AES historical involvement in film sound. The lack of electroacoustical response reference data for Digital Cinema systems was underscored by Dr. Floyd Toole’s statement, “It seems that no real science has been done in terms of Digital Cinema Sound.” Dr. Toole, Vice Chair of the committee, is developing a ½ day seminar on these issues to be held in L.A. in March that will serve as the first meeting of the committee.

McCarty underscores the point that global acousticians, engineers and systems installers have expressed the need for a working standard. “In simple terms, what is recorded digitally in the studio does NOT sound the same at the theatrical end,” McCarty says. “As an art form our goal should be consistency of sound quality. Acoustical design of theaters is typically incorrect for sound reproduction in large rooms. Current soundtrack EQ reproduction curves are inconsistent with large-room audio practice and, with the rest of the audio industry. And, loudspeaker technology typically used in theaters has yet to be optimized for proper playback of wide bandwidth soundtracks. Basically,” McCarty concludes, “the current Digital Cinema Audio System is simply not the best we can do. The AES is committed to improving this situation.”

About AES

The Audio Engineering Society was formed in 1948 by a group of concerned audio engineers. The AES counts over 14,000 members throughout the U.S., Latin America, Europe, Japan and the Far East. The organization serves as the pivotal force in the exchange and dissemination of technical information for the industry.
