Multi-Channel Video Editing via Metadata-Aligned Light Field Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of managing and editing video segments that utilize multiple camera sources, capturing various spatial, intensity, and color information, poses challenges in data management and editing, as existing tools struggle to effectively handle the relationships among these sources and assist editors in combining and manipulating metadata from multi-channel sources.
Innovation Solution
A method and system that dynamically combine and align multiple input channels with metadata to create a synthetic light field source, enabling editors to define output views based on specified parameter ranges, including spatial and color parameters, through a graphical user interface, allowing for flexible management and editing of multi-channel media compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple camera sources are used to capture various spatial, intensity, and color information, then the quantity and quality of media resources are improved, but the device complexity and difficulty of data management increase
Solution Approach 1:
The system segments the multi-channel media data into organized channels with metadata, allowing each channel to be managed independently while maintaining relationships. This segmentation enables better organization of the increased quantity of media resources from multiple camera sources.
Solution Approach 2:
The editing system is designed with universal functionality to handle multiple types of media channels (video, audio, metadata) and various camera configurations. This multi-functionality allows the system to manage diverse media resources without requiring separate specialized tools for each type.
2Adaptability or versatility
If multiple camera sources capture expanded scene information, then the versatility of media applications is improved, but the ease of operation for editors deteriorates
Solution Approach 1:
Metadata acts as an intermediary between the complex multi-camera capture system and the editing interface. It provides structured information about each channel's properties (spatial, temporal, color) that simplifies the editor's interaction with the complex data structure while maintaining full versatility.
Solution Approach 2:
The system allows editors to dynamically change parameters such as channel selection, metadata filtering, and view configurations. This parameter-driven approach maintains versatility for different media applications while simplifying operations through standardized parameter adjustments rather than complex manual configurations.
3Reliability
If existing editing tools are used with multi-channel sources, then compatibility is maintained, but the productivity of editing processes deteriorates
Solution Approach 1:
The system merges the functionality of traditional editing tools with new multi-channel management capabilities in a unified interface. This combination maintains compatibility with existing workflows while adding enhanced productivity features for handling multiple camera sources and metadata.
Solution Approach 2:
The system performs preliminary organization of multi-channel data through metadata tagging and channel grouping before the editing process begins. This preliminary action reduces the time and effort needed during actual editing operations, thereby improving productivity while maintaining tool compatibility.
Data Source
AI summary
Methods and systems for constructing media output by combining multiple input media channels corresponding to different views of a scene. The construction involves combining channels that have different spatial ranges and/or color ranges so as to produce a constructed output having a range that is a composite of input channel spatial and/or color ranges. The constructed output is generated dynamically from available input channels in response to output requirements specifying a view defined in part by spatial and/or color parameter ranges. Available input channels are represented by a single multi-channel source object comprising a hierarchy of grouped and aligned channels, with individual media essence files at the lowest level. Input channel ranges and relationships among the ranges are specified by metadata associated with each channel. During editing, input channels may be added, removed, or changed and the range and nature of the constructed media output are updated dynamically.
