Achieving Cinematic Motion with High Dynamic Range

This paper will explore how the appearance of cinematic motion (the characteristic balance of smoothness and realism of motion commonly used in cinema) is affected by high dynamic range (HDR) presentation. We will report on a psychovisual experiment that investigated how observers rated the smoothness of motion between scenes of different motion types (pans, action, slow movement), frame rates, and luminance levels. We found that in order to match the level of cinematic motion in todays' non-HDR presentation, the frame rate may need to either remain at 24 frames per second (fps) or be increased to 30fps, depending on the type of motion and the luminance level of the scene. We conclude that by selecting the appropriate frame rate depending on the motion type in each scene, content creators will be able to achieve the desired cinematic motion without compromising their use of the HDR color palette.
