Video Clip Generation Using NLP Theme Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods struggle to efficiently generate derivative video content by identifying themes and topics within media, such as videos, which limits the ability to create personalized and relevant clips in a timely and accurate manner.
Innovation Solution
The use of natural language processing (NLP) and computer vision (CV) technologies to analyze video content, identify themes, and generate video clips by associating keywords with themes, determining statistical relevance, and creating time codes for clip generation, enabling the automatic production of derivative content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual methods are used to identify themes and generate derivative video content, then the quality and relevance of clips can be maintained through human decision-making, but the productivity and speed of content creation are severely limited
Solution Approach 1:
The system enables self-service by automatically identifying themes, topics, and significant moments in video content without human intervention. The NLP and CV systems process video files, extract meaningful segments, and generate derivative content autonomously, allowing the system to serve itself in content creation tasks
Solution Approach 2:
The patent replaces manual mechanical processes (human viewing, analyzing, and selecting video segments) with automated NLP and CV systems. These systems process video files, identify themes through text analysis, detect visual elements, and automatically generate clip boundaries, substituting human cognitive work with computational processes
2Measurement precision
If comprehensive analysis of all video content is performed to ensure accurate theme identification, then the precision of clip generation is improved, but the processing time and complexity increase
Solution Approach 1:
The system segments the complex analysis task into distinct components: NLP processing for theme identification from audio/transcripts, CV processing for visual element detection, statistical relevance analysis for filtering, and clip generation. Each module handles a specific aspect of the analysis, making the overall complex system manageable and efficient
Solution Approach 2:
The system performs partial analysis by focusing on statistically relevant word groupings and expressions rather than analyzing every single word or frame. By identifying correlations between grouped expressions and video segments, the system achieves accurate theme identification without exhaustive processing of all content
3Reliability
If extensive processing and filtering of word groupings is performed to ensure relevance, then the quality of personalized clips is improved, but the processing time increases
Solution Approach 1:
The system performs preliminary grouping of words into thematic categories before the actual clip generation process. By pre-organizing word groupings by theme and calculating statistical relevance in advance, the system prepares filtered and organized data structures that speed up the subsequent clip generation and reduce real-time processing requirements
Data Source
AI summary
A system for generating video clips includes a video processing system configured to receive a video file from a video capture system, and to create video clips based on significant moments identified in the video file. The video processing system includes a file storage and database system configured to store the video file, and storing an ontology and keywords associated with themes that are pertinent to the overall theme of the video file. The video processing system also includes a natural language processing (NLP) moments module configured to identify themes contained in the video file using the ontology and the keywords, and to identify time codes associated with the identified themes. The video processing system also includes a video clip generator configured to generate video clips based on the identified time codes.
