Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video editing tools require manual alignment of audio and video parts, making it time-consuming for users without experience in designing musical remixes, and there is a need for an automated method to create video remixes that are pleasing to the ear.
Innovation Solution
A method for automatically cutting a source video into sub-sequences based on audio onsets and rearranging them into a video remix with a predetermined pattern, which imparts a rhythmic quality to the audio, allowing for easy creation of musical video remixes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual alignment of audio and video parts is performed, then precision of synchronization is improved, but time consumption increases
Solution Approach 1:
The system automatically detects audio onsets and generates video remixes without requiring manual user intervention for alignment. The automated onset detection algorithm analyzes audio tracks and automatically determines synchronization points, allowing the system to serve itself rather than requiring manual user alignment operations.
Solution Approach 2:
The patent replaces manual mechanical alignment operations with automated computational algorithms. Instead of manually adjusting audio and video synchronization, the system uses computer-based onset detection and automated rearrangement algorithms to achieve precise synchronization, substituting human manual operations with automated digital processing.
2Productivity
If automated video remixing is implemented, then productivity is improved, but complexity of the system increases
Solution Approach 1:
The patent segments the video remixing process into distinct automated stages: audio onset detection, excerpt selection based on onsets, sub-sequence division, and pattern-based rearrangement. By breaking down the complex remixing task into manageable sequential segments, the system achieves automation while keeping each individual step relatively simple and manageable.
Solution Approach 2:
The system uses configurable parameters such as predetermined patterns, excerpt lengths, and onset thresholds to control the automated remixing process. By adjusting these parameters, users can customize the output without increasing operational complexity, as the automated system handles the actual rearrangement based on the provided parameter settings.
3Measurement precision
If manual alignment is required, then precision of audio-video synchronization is improved, but ease of operation decreases
Solution Approach 1:
The system performs self-service by automatically detecting audio onsets and generating synchronized video remixes without requiring user expertise in manual alignment. The automated onset detection and rearrangement processes eliminate the need for users to have experience in designing musical remixes, significantly improving ease of operation while maintaining synchronization precision.
Solution Approach 2:
The patent introduces an intermediary automated processing layer between the input video and the final remix output. This intermediary system handles the complex synchronization tasks automatically, acting as a mediator that translates simple user inputs into precisely synchronized audio-video outputs without requiring direct manual alignment operations from the user.
