Introducing – Tools for Cinema Quality Assurance

Cinema Test Tools for the non-Technical Manager – Post Installation Quality Assurance Has Begun

Cinema Test Tools is a free resource for the cinema industry, tuned most particularly for the non-technical manager. The tools include several DCPs, all with interesting means of testing the sound and picture quality for the interested by lightly trained staff. The lessons on sound and light are written to provide a foundation to communicate with the technician who must respond quickly and well to the information that they discover.

The key is a free Managers Walk Through Checklist that correlates with the many DCPs. It helps bring an understanding of the many nuances of the auditorium's situation in a straightforward way. 

Uncountable little pieces of experience add to a wealth of knowledge that should be shared for the betterment of the community. Please contribute.

More Light on HRF

Regal Cinema has put up a page giving a few answers about HFR – High Frame Rate, in this case, high frame rate 3D. "This innovative format presents the picture in 48 frames per second (fps), which is closer to what the human eye actually sees."

...in 3D only. ...another option for each consumer's taste...

It doesn't offer a compelling reason, as if they are holding back their cards. "It brings more structured and saturated light to the eye" is probably too much. Explaining that Cameron and others are choosing 60 frames is bad form, since the Hobbit group chose 48 for a valid reason.

I think I'll ask for some of the Sony closed caption glasses to compare.

Tripping Over the Laser Light – Fantastic~!

There needs to be some stage setting before getting to the post-play-out conversation of Christie's monumental effort of presenting Hugo at the IBC's Monday Big Movie Night. So, before elaboration on the details: Hats off to Christie and hats off to lasers – Great Science, Great Movie, Great Effort, Great Presentation.

There are two important "everybody knows" issues that need eliminating before discussing the Christie effort. The first is to counter the wishful thinking that has morphed into a meme-life of its own. It gets stated by people who should know better and was even in an earlier slide presentation in the same auditorium on the same afternoon of the Hugo presentation.

The meme says: There is a SMPTE/ISO/DCI luminance standard for 2D presentations (48 candelas per square meter, or 14 foot-Lamberts), but the DCI 3D document only speaks to starting the sequence with the left eye, 4:2:2 data streams and one other issue and therefore, since it doesn't speak to luminance, it therefore allows a de facto standard of 4.5 ft/Lamberts.

That is as insane as saying that since the 3D standard doesn't speak to issues of following the fire code, EXIT signs don't need to be illuminated during 3D presentations. [DCI_Stereoscopic_DC_Addendum.pdf]

Lasers, Christie, IBC...Silver Screen Why [Update 2]

We are heartened by the consistent heartbeat of laser systems being shown at events, each time getting more and sometimes even better. This time, IBC will see Christie's first laser exposition, an anticipated move since their parent company Ushio bought the California laser company Necsel late in 2010. On Monday night of IBC 2012, Christie will be showing a 3D version of the movie Hugo which they are billing as the world's first showing of a complete motion picture in laser 3D.

We aren't heartened by the announcement that they are using a high gain screen, which has the following effect [drawing updated in Update 2 of this article -Ed.], shown in the graphs and attempted to visualize in the drawing of the RAI Auditorium. If a high gain screen wheren't enough, they are also using a silver screen, which just makes niggling problems worse.

Many questions.

Light Levels In Cinema – From the Screen's Viewpoint

"Because of the low light efficiency of all 3D systems (some are better than others but all lose a lot of light) the de facto screen brightness standard for 3D presentations is 4.5 Foot Lamberts (fL) which is only one third of the agreed standard for 2D of 14fL."

So says the introduction to the Harkness Screens free webinar (29 February: 15:00 GMT/10AM Eastern US/ 7AM Pacific US).
