Introducing – Tools for Cinema Quality Assurance


Cinema Test Tools for the Non-Technical Manager 

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 Online Managers Online 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. 

DCI – New HDR and Direct View Display Docs

DCI has released two new documents for industry review, one dealing with emissive technology (describing them as 'often LED pixels', but leaving the door open for anything) and the other which deals with HDR – High Dynamic Range – displays in post-production and exhibition theaters "so that consistent and repeatable color quality can be achieved."

Both documents include a paragraph that begins: "This document is not a DCI Specification" plus a statement that invites review and comment and an email to send comments to, which other recent versions of these documents have done as well.

The difference is that these documents are very fleshed out, reading more like a SMPTE document than a brief one what one should consider, and are complete with Normative References and a Glossary, in addition to the required formulas and charts.

Interesting highlights include the luminance parameters for 500 candela/m2 (146 fL) with stricter tolerances and roll offs at the edges and corners. A minimum black level of 0.005 cd/m2 is specifically mentioned, which is a 5 decimal point swing, or 100,000:1. It was nice to see that P3D65 makes an appearance as the White Point, coming on the heels of the latest revision of ST 2067-102:2017

SDR ranges are also specified, with a black level under 0.01 cd/m2 being the level under which the display shall never reproduce. This might protect grey fuzzies from appearing in place of blacks in SDR releases shown through HDR machinery. References to 5,000:1 for SDR are mentioned in the Direct View Display document, but not the HDR. In fact, there is an actual paucity of the word Contrast, though not a is mentioned once and implied a few times.

High Frame Rates are also detailed in the Direct View document, in Edit Units per second.
