Video Punchout Generation via Field of View Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Creating video edits from videos with wide fields of view is challenging due to the complexity of determining relevant moments and spatial locations within the videos, making the process time-consuming and complicated.
Innovation Solution
A system that determines the field of view for multiple video content streams, generates viewing windows based on these fields of view, and creates punchouts or excerpts of the videos within these windows, allowing for efficient editing and combination of video content with different field of views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If users manually determine moments and fields of view in wide field of view videos, then video edit quality can be controlled, but the process becomes time-consuming and complicated
Solution Approach 1:
The system performs automatic field of view determination and punchout generation without requiring manual user intervention. The processor automatically analyzes wide field of view video content, determines relevant moments and appropriate fields of view, and generates punchouts, allowing the system to serve itself rather than requiring user operation for each editing decision.
Solution Approach 2:
The system changes the parameter of field of view from wide to narrow by automatically determining and applying appropriate punchout regions. By dynamically adjusting the field of view parameter based on content analysis, the system transforms wide field of view video into focused punchout segments without manual specification.
2Productivity
If automatic field of view determination is implemented, then editing efficiency is improved, but complexity of the system increases
Solution Approach 1:
The processor is designed to perform multiple functions: it determines field of view, identifies relevant moments, generates punchouts, and combines video content. By making the processor universal and multi-functional, the system achieves automatic editing efficiency while consolidating complexity into a single processing unit rather than requiring multiple specialized components.
3Adaptability or versatility
If punchouts are generated from videos with different field of views, then video content integration is improved, but alignment and coherence become more difficult
Solution Approach 1:
The system performs preliminary field of view determination and punchout generation before final video combination. By pre-processing each video source to determine appropriate fields of view and generate aligned punchouts, the system establishes temporal and spatial correspondence between different video sources in advance, making subsequent alignment easier and more precise.

AI summary
A video edit of first video content and second video content may be generated based on the fields of view of the first video content and the second video content. Based on the fields of view of the first video content and the second video content, a first viewing window for the first video content and a second viewing window for the second video content may be determined. The viewing windows may define one or more extents of the corresponding visual content. The video edit may include a punchout of the first video content based on the first viewing window and a punchout of the second video content based on the second viewing window.
