High Frame Rate Cinematic Motion Blur Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-frame-rate motion pictures often present a hyper-realistic appearance that detracts from the cinematic experience, making it difficult for viewers to suspend disbelief and enjoy the movie, as excessive detail can be distracting and lead to a 'soap opera' look similar to live television.
Innovation Solution
The introduction of controlled motion blur, either during photography or post-production, allows producers to selectively reduce the level of detail in high-frame-rate motion pictures, mimicking the cinematic artifacts of traditional 24 frames per second film photography to maintain a cinematic appearance while enhancing realism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high frame rates (48 fps) are used for photography and projection, then spatial and temporal resolution are improved, but the cinematic appearance is lost and a hyper-realistic 'soap opera' look is created that distracts viewers
Solution Approach 1:
The patent applies parameter changes by modifying the shutter angle parameter during high-frame-rate photography. By using a reduced shutter angle (less than 180 degrees, such as 90 degrees) at 48 fps, the patent achieves a compromise between the sharpness of high frame rates and the motion blur characteristic of cinematic appearance, thereby resolving the contradiction between improved resolution and hyper-realistic appearance
2Manufacturing precision
If high frame rates are used, then clarity and detail are increased, but viewer immersion is reduced due to excessive detail that distracts from the storyline
Solution Approach 1:
The patent applies local quality by selectively applying different shutter angles to different scenes or sequences within a motion picture. This allows certain scenes to have the sharp, clear appearance of high frame rates while other scenes have the motion-blurred cinematic appearance, thereby maintaining viewer immersion in scenes where it is most needed while preserving clarity where appropriate
3Object-generated harmful factors
If traditional 24 fps photography is used, then cinematic appearance with motion blur is achieved, but spatial and temporal resolution are reduced
Solution Approach 1:
The patent applies dynamics by enabling flexible switching between different frame rates (24 fps, 48 fps, or other rates) and different shutter angles throughout the production. This dynamic approach allows the filmmaker to optimize each scene individually, achieving both cinematic appearance and high resolution where needed, rather than being locked into a single fixed parameter set

AI summary
A method is disclosed whereby motion pictures photographed and exhibited at high frame rates, typically 48 frames-per-second, are modified to impart a cinematic appearance which tempers the level of motion detail inherent at such high frame rates. Motion pictures can be photographed either on film or by digital means. A controlled amount of motion blur is imparted selectively to certain scenes, sequences, frames or components of images. This can be accomplished by using different shutter angles for digital photography, or by imparting motion blur in post-production. The result is a motion picture that provides viewers with a cinematic appearance while at the same time, retains the spatial and temporal resolution of HFR, due to the high frame rate of photography and exhibition.
