[email protected] Content Creation Pushing Quality

Excellent 3D work is now hitting the big screen regularly, the latest being the exceptional Hugo. One imagines that eventually the circle of cognoscenti will Venn out of “Friends of Cameron”, perhaps even developing from the semi-pro end of the market. If it does, it will be because of efforts of people like the [email protected] Consortium who put out great information, white papers and tutorials, trying to protect the eye-balls of us all.

The latest is a white paper from Robert Boudreau which documents his adventure of buying a JVC 1080 3D camera for his daughter’s wedding. High Quality Home 3D Movies Using the JVC Full HD 3D Camcorder with the Toshiba Autostereo Laptop or the Sony Shutter Glasses Laptop

Silver Screens – French Quality Officially Declines?

French cinema and television standards are like California pollution standards; more strict than the norm, with active regulation and monitoring to keep standards high for this important section of their industrial and consumer base.

The SMPTE and ISO rules for screen brightness are clear. Luminance Uniformity at the corners and sides of the screen is specified at 85% of the luminance at the center of the screen. There is an allowed tolerance in theaters – 70% to 90% of the center level. (The center level is 48 candelas per square meter, with a tolerance of 10.2 cd.m2.)

The French standard is tighter, specifying no greater than 75% at the corners and edges. The CNC is about to release a technology statement that will abdicate their role as the arbiters of quality in this regard.

DCI Talks NIST

NIST logo, smallCompliance in DCinema means compliance with the details of several standards groups and organizations. Video compression and Decompression will be compliant with JPEG 2000, a set of standards of the Joint Photographic Experts Group, audio formats are specified by AES (Audio Engineering Society) formats and encryption within the Advanced Encryption Standard of the National Institute of Standards and Technology (NIST) and the Federal Information Procession Standards (FIPS). Of course, the over-riding standards group who tied all the nuance together is the Society of Motion Picture and Television Engineers (SMPTE).

Sayonara CD-ROM: SMPTE

SMPTE LogoThe process of staying on top of standards has advanced another step to modernity. Instead of a CD-ROM subscription plan, which naturally could only be kept up to date at production cycle points, SMPTE has announce a new online subscription service (beginning 1 November) that allows online access to SMPTE Standards, Recommended Practices, Engineering Guidelines and Registered Disclosure Documents. The non-member price is $800, while individual members pay $500.

Why is this interesting? As we see from the recent IEEE 1722 (A/V over ethernet) voting and passage, the protocol still has another 6 weeks to wait before approved by the Board, plus another 3 months (at least) waiting for the publication cycle – getting the magazine printed and distributed. Only then, after publication, can the protocol be called a standard. But until then, people involved with the process might have variations of the documents, but the interested public will have nothing. Online publication will help speed this process. 

The following email to the membership explains the details and contact information for questions and suggestions…and yes, if you have a subscription now, it will be converted to online…tres cool.
