Paper on frame rate artifacts -- 120fps HFR at

Post by Chief Blur Buster » 10 Sep 2019, 01:34

There's a great paper about HFR here, done by Pickfair Institute:

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.
