Commonly, movies are displayed with a frame rate of 24 frames per second. This frame rate is selected so that the inertia of the eye perceives the successive images as a continuous motion sequence. However, this form of presentation introduces minor blurring and image judder during rapid changes in motion.
With High Frame Rate(HFR), sharper representations without motion bl ur and judder effects become possible. High Frame Rate (HFR) means a higher frame rate. This can be 48 frames per second or, as in the UHD format, 100 or 120 frames per second.
HFR technology can be used in 2D and 3D cinemas, as well as in high-definition television or Ultra HDTV. With HFR technology, different images are displayed one after the other and not, as with other technologies, two identical individual images are projected one after the other. As a result, even extremely fast motion sequences are resolved in detail and the projection looks extremely realistic.
