The ASC (American Society of Cinematographers) will soon release StEM2, which stands for Standard Evaluation Material which is designed to test new technology implications on the imaging chain. This will be offered as a free download to anyone in the industry.

So what exactly is StEM2?

Essentially the Standard Evaluation Material II (StEM2) project is a short film created by the ACS to provide standardized viewing material that is designed to aid in the development and calibration of technology impacting the modern imaging chain. StEM2 test packages will be available in early 2022 to download for free in all common theatrical and home TV formats.

The short film “The Mission,” is a professionally produced short film for the StEM2 initiative, and it was done to emulate a high-end movie. Under the direction of the ASC, the film was designed to test exhibition and streaming systems, displays, and image-processing tools used in production and post.

The Mission” was carefully conceived to exploit and challenge today’s exhibition and image processing systems. StEM2 utilized the Academy Color Encoding System (ACES) throughout the entire pipeline. The project evaluated the challenges of moving meticulously crafted images through cloud workflows, including camera-to-cloud, dailies, editing, rendering and creation of deliverables while simultaneously maintaining artistic intentions. Utilizing an array of production environments, it was shot on location and on virtual production stages in July, capturing scenes shot in a dark cave, the desert, car interiors (day and night), city streets (night exteriors), and a dimly lit hospital (night interiors).

Additional parameters tested by “The Mission” include image high dynamic range, diverse skin tones, high-resolution detail, in-camera VFX, fast-moving action, and visuals to tax compression algorithms and image processing software.

As exhibition technology continues to advance, there is a critical need for baseline evaluation material originated by neutral and trusted third-party imaging experts

StEM2 offers the industry the information needed to support developments and advancements of products and solutions for image creation. Everyone from filmmakers, studios, and post houses to engineers, technologists and manufacturers are affected by the technical complexities impacting storytelling.

StEM2 was produced with significant backing from studios, technology companies, and industry leaders, including a seed grant from Epic MegaGrants, as well as major support from the Academy of Motion Picture Arts and Sciences (AMPAS) Scientific and Technical Council.

StEM2 is an updated version of the ASC’s StEM1 project, which was a collaboration of the ASC and Digital Cinema Initiatives (DCI) in 2004. StEM1 helped DCI to establish technical parameters for digital cinema specifications during the transition from film print projection. It continues to be a bellwether for the industry in evaluating first-generation digital developments.
