This paper will explore how smoothness of motion may be affected by high dynamic range production. We will report on a psychovisual experiment that investigates how observers rate the smoothness of motion between various motion types in a scene (pans, action, slow movement), various frame rates, as well as various luminance levels. We will show that to match the level of cinematic motion in the reference, the frame rate may need to be adjusted depending on both the luminance and the motion type in a scene. Will illustrate how by selecting the appropriate frame rate for each scene, content creators will be able to obtain the desired cinematic motion without compromising their use of the High Dynamic Range color palette.
