Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media editors face difficulties in aligning and synchronizing multi-camera footage, as manually editing clips from different angles is time-intensive and prone to errors, requiring manual correction across multiple timelines or projects.
Innovation Solution
A media-editing application that automatically assigns, orders, and synchronizes media clips from multiple cameras using metadata, creating a multi-camera media clip that aligns capture times and allows for easy editing and modification across different angles within a project.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual editing of multi-camera clips is performed, then editing flexibility is maintained, but time consumption increases significantly
Solution Approach 1:
The system performs preliminary actions by automatically assigning clips to angles and synchronizing them before the editing process begins. The media editing application automatically assigns media clips to different angles based on metadata and synchronizes their capture times, so that when editors need to work with the clips, the alignment work is already done, significantly reducing the time required during manual editing.
Solution Approach 2:
The system performs self-service by automatically handling the time-consuming tasks of clip assignment and synchronization without requiring manual intervention. The media editing application autonomously processes multiple camera clips, assigns them to appropriate angles using metadata, and synchronizes their timing, thereby freeing editors from repetitive manual tasks and improving overall productivity.
2Manufacturing precision
If manual alignment of clips from different cameras is performed, then precision can be controlled, but the process becomes error-prone and time-intensive
Solution Approach 1:
The system uses feedback mechanisms to verify and adjust clip synchronization. The media editing application compares capture times and other metadata from different cameras, provides feedback on alignment status, and makes corrections automatically. This feedback loop ensures high alignment precision while simplifying the operator's task, as the system self-corrects rather than requiring manual precision control.
Solution Approach 2:
The patent replaces the mechanical manual alignment process with an automated computational system. Instead of editors manually adjusting clips frame-by-frame, the media editing application uses computer processing to automatically assign clips to angles, compare timestamps, and synchronize them. This substitution of manual mechanical operations with automated digital processing eliminates errors and reduces complexity.
3Reliability
If corrections are made in multiple locations across timelines, then consistency can be maintained, but the workload multiplies significantly
Solution Approach 1:
The system achieves universality by creating a centralized multi-camera clip structure that can be referenced across multiple timelines and projects. The media editing application builds a master organization of clips with consistent metadata and synchronization data that serves as a universal reference. When corrections need to be made, they can be applied once to the master structure and automatically propagate to all usages, maintaining consistency without multiplying workload.
Solution Approach 2:
The patent implements a nested structure where individual media clips are organized within angle groups, which are in turn organized within multi-camera clip references, which can be referenced by multiple timelines and projects. This nested organization allows corrections at higher levels to automatically affect lower levels, enabling consistent updates across the entire hierarchy without requiring separate operations in each location.
