Video Synchronization via Audio Event Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual editing of video clips to synchronize with audio tracks is time-consuming and discourages users from achieving synchronization.
Innovation Solution
A system that automatically edits video clips by determining video events and aligning them with audio tracks using audio event markers, allowing for automatic synchronization and playback with selected audio tracks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual editing is used to synchronize video clips with audio tracks, then synchronization precision can be achieved, but time consumption increases significantly
Solution Approach 1:
The system enables automatic synchronization where the video editing system performs the synchronization task autonomously by detecting video events and automatically aligning them with audio track markers, eliminating the need for manual user intervention in the synchronization process
Solution Approach 2:
The patent replaces manual mechanical editing operations with automated computational processes that detect video events, identify audio markers, and automatically adjust video timing to achieve synchronization without human intervention
2Loss of time
If automatic synchronization is implemented, then time consumption is reduced, but system complexity increases
Solution Approach 1:
The system divides the video clip into segments and identifies specific video events within those segments, allowing the complex synchronization task to be broken down into manageable steps that can be processed automatically
Solution Approach 2:
The system introduces audio event markers as intermediary elements that serve as reference points between the video and audio tracks, enabling automatic alignment without requiring complex direct synchronization algorithms

AI summary
Video clips may be automatically edited to be synchronized for accompaniment by audio tracks. A first version of a video clip may be made up from stored video content. The first version of the video clip may include one occurrences of video events. An audio track may include audio event markers. The first version of the video clip may be synchronized so that moments within the video clip corresponding to occurrences of video events are aligned with moments within the audio track corresponding to audio event markers. Changes to the audio track may be determined. A second version of the video clip may be synchronized so that moments within the video clip corresponding to occurrences of video events are aligned with moments within the changed audio track corresponding to audio event markers.
