360-Degree Video Post-Production Using Point of View Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video post-production tools are inadequate for handling 360-degree videos, as they were developed for 2D rectilinear videos and struggle with the unique challenges of 360-degree video editing, such as aligning and stabilizing omnidirectional content.
Innovation Solution
The method and system for 360-degree video post-production utilize points of view (POVs) to facilitate editing by applying rectilinear video post-production techniques to specific subsets of the 360-degree composition, integrating edited layers back into the 360-degree environment, and employing tracking information to stabilize the 360-degree composition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing 2D rectilinear video post-production tools are used for 360-degree videos, then traditional editing methods can be applied, but the tools cannot properly handle alignment and stabilization of omnidirectional content
Solution Approach 1:
The patent introduces an intermediary coordinate transformation system that converts 360-degree spherical video data into rectilinear formats compatible with traditional editing tools, then transforms the edited results back into 360-degree format. This mediator layer enables existing 2D tools to work with 360 content without compromising alignment accuracy, as the transformation maintains spatial relationships throughout the editing process.
2Productivity
If 360-degree video editing is performed directly without using POVs, then the complete omnidirectional content can be accessed, but the complexity of handling and aligning layers increases significantly
Solution Approach 1:
The patent segments the 360-degree video into multiple Points of View (POVs), each representing a specific viewing direction or camera angle. This segmentation allows editors to work with individual rectilinear subsets of the spherical content using familiar 2D tools, significantly reducing system complexity while maintaining productivity. The segmented POVs can be independently edited and then reassembled into the complete 360-degree composition.
3Loss of time
If tracking information is not used for stabilization, then the processing time is reduced, but the stabilization quality of the 360-degree composition deteriorates
Solution Approach 1:
The patent applies tracking and stabilization operations to individual Points of View (POVs) before the final 360-degree composition is assembled. This preliminary action on segmented content allows stabilization to be performed more efficiently on smaller rectilinear subsets rather than the complete spherical video, reducing overall processing time while maintaining high stabilization quality through the use of tracking information.

AI summary
In accordance with example embodiments, the method and system for 360-degree video post-production generally makes use of points of view (POVs) to facilitate the 360-degree video post-production process. A POV is a rectilinear subset view of a 360-degree composition based on a particular focal length, angle of view, and orientation for each frame of the 360-degree composition. Video post-production editing can be applied to a POV by the user, using rectilinear video post-production methods or systems. The rectilinear video post-production editing done on the POV is integrated back into the 360-degree environment of the 360-degree composition. In accordance with example embodiments, the method and system for 360-degree video post-production comprises identifying a point of view in a 360-degree composition; applying video post-production editing to the point of view; and aligning a new layer containing the video post-production editing with the point of view in the 360-degree composition.
