Audiovisual Editing System Synchronizing Text and Media Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Journalists and editors face challenges in synchronizing audiovisual materials with corresponding text segments in television news production, requiring an efficient system to edit both audiovisual and textual components while ensuring accurate timing and format alignment.
Innovation Solution
An audiovisual editing system that associates media segments with text segments, allowing for intuitive editing through a data structure representing the story as a list of media and text segments with timing control elements, enabling automatic trimming and synchronization of clips to match the duration of text or audiovisual materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If journalists manually synchronize audiovisual materials with text segments, then timing alignment can be achieved, but the process is time-consuming and error-prone
Solution Approach 1:
The system performs preliminary actions by automatically transcribing audiovisual content into text segments with embedded timing metadata before the editing process begins. This pre-synchronization of text with temporal information eliminates the need for manual timing alignment during editing, reducing both editing time and errors while maintaining precise timing alignment.
Solution Approach 2:
The patent introduces an intermediary layer of structured data containing timing metadata that mediates between audiovisual materials and text segments. This intermediary data structure automatically captures and preserves synchronization information, allowing editors to work with pre-aligned content without manual intervention, thus resolving the contradiction between precision and time consumption.
2Adaptability or versatility
If the system provides extensive editing controls for both audiovisual and text segments, then editing flexibility is improved, but the interface complexity increases
Solution Approach 1:
The system merges the editing of audiovisual segments and text segments into a unified interface where both types of content are manipulated together within integrated data structures. This combination allows editors to simultaneously control timing, content, and synchronization without switching between separate tools, maintaining flexibility while reducing interface complexity through consolidation.
Solution Approach 2:
The patent creates a universal editing framework that handles multiple types of segments (audiovisual, text, timing metadata) through a single set of editing operations. This multi-functional approach allows the same interface controls to work across different media types, providing extensive editing flexibility without proportionally increasing interface complexity.
3Measurement precision
If automatic trimming is enabled to synchronize clips with text duration, then synchronization accuracy is improved, but manual control is reduced
Solution Approach 1:
The system implements dynamic controls for automatic trimming where the level of automation can be adjusted based on user needs. Editors can enable or disable automatic trimming, adjust trimming parameters, or apply automatic trimming selectively to specific segments. This dynamic approach maintains high synchronization accuracy through automatic processes while preserving manual control when needed, resolving the contradiction between precision and operational flexibility.
Data Source
AI summary
An audiovisual editing system that permits a journalist and other editors to edit both audiovisual and corresponding text segments included in a story. The data structure representing a story includes a list of media segments and a list of corresponding text segments. Each media segment has a type, such as script, SOT and voice, and includes a list of video clips. Each SOT segment or voice segment includes a list of timing control elements that determine the length of a media segment. The difference in the duration of the audiovisual material and the duration of the related text may be displayed to the editor, making it easier for the editor to match video to a script. Similarly, the duration of voice and SOT clips can be displayed to the editor, making it easier for the editor to match the video to the audio.
