SMPTE 2017: Variable Frame Rate Display for Cinematic Presentations
The accompanying technical manuscript for this presentation is available here: http://ieeexplore.ieee.org/document/8...
While motion pictures have traditionally been captured and presented at a frame rate of 24 frames per second, recent advancements have enabled the capture and presentation at higher frame rates of 48, 60, and even 120 frames per second. Capture and presentation at higher frame rates provide improvements in clarity and motion rendition, but come at the cost of increased storage space, processing, and workload for the entire motion picture. Motion picture creators want the capability to reduce the motion judder, and blur associated with capturing moving images while still maintaining the cinematic feel of their creations. By introducing a method where the projector can vary the frame rate during playback, the scenes that most benefit from higher frame rates can be captured and presented at that rate, while the scenes that do not benefit from higher frame rates can be captured and presented at lower frame rates. The engineers working with DLP Cinema at Texas Instruments have come up with a method to allow changes to the displayed frame rate to be communicated effectively through the entire playback chain during a presentation with no visible artifacts on screen before, during, or after the transition. This Variable Frame Rate (VFR) capability enabled by the latest DLP Cinema systems is further described in this paper.

SMPTE (pronounced "simp-tee"), the organization whose standards work has supported a century of advances in entertainment technology and whose membership spans the globe, holds the SMPTE Annual Technical Conference & Exhibition in Los Angeles each October. The event is considered the world's premier forum for the exploration of media and entertainment technology. More information about this year’s upcoming event is available at www.smpte2018.org.
The people of the Society of Motion Picture and Television Engineers, or SMPTE, have sorted out the details of many significant advances in media and entertainment technology, from the introduction of "talkies" and color television to HD and UHD (4K, 8K) TV. Since its founding in 1916, SMPTE has received an Oscar® and multiple Emmy® Awards for its work in advancing moving-imagery engineering across the industry. SMPTE has developed thousands of standards, recommended practices, and engineering guidelines, more than 800 of which are currently in force today. SMPTE Time Code™ and the ubiquitous SMPTE Color Bars™ are just two examples of SMPTE's notable work. As it enters its second century, SMPTE is shaping the next generation of standards and providing education for the industry to ensure interoperability as the industry evolves further into IT- and IP-based workflows. Visit www.smpte.org for more information.
SMPTE's global membership today includes more than 7,000 members: motion-imaging executives, creatives, technologists, researchers, and students who volunteer their time and expertise to SMPTE's standards development and educational initiatives. A partnership with the Hollywood Professional Association (HPA) connects SMPTE and its membership with the businesses and individuals who support the creation and finishing of media content. Information on joining SMPTE is available at www.smpte.org/join.
