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.
Technical Depth of Presentation
We plan for about 50% of our presentation to be at the fundamental level to get the audience all on the same page. Then second half of the presentation will be more on the intermediate/advanced depth, but we price ourselves in making highly technical concepts approachable for even the technical novice.
What Attendees will Benefit Most from this Presentation
We plan to make this presentation applicable for a wide audience. We will cover the high level impact more appropriate for executives and managers. We will also include the technical results from our psychovisual experiment that will be more appropriate for engineers and technologists.
Take-Aways from this Presentation
- The perception of cinematic motion depends on the motion type in a scene and luminance level
- To maintain consistent cinematic motion, the frame rate must be modified on a scene by scene basis
- The impact of motion being too smooth is less than the impact of motion being abrupt
