Anchor Point Synchronization for Video Overlay Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video editing software lacks intuitive features for synchronizing overlay content, such as audio tracks and transitions, with video clips, making it difficult for users to maintain synchronization during editing operations like cutting, rearranging, or adding new content.
Innovation Solution
A system that allows users to anchor specific points in overlay content to corresponding points in video content, ensuring synchronization regardless of editing operations, by displaying video clips as thumbnails aligned to a timeline and enabling users to move and adjust overlay content automatically with video content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If overlay content is added to video content without anchoring, then the video editing process becomes simpler, but synchronization between overlay content and video content is lost during editing operations
Solution Approach 1:
The system establishes an anchor point relationship between overlay content and video content before editing operations occur. This preliminary anchoring action ensures that when editing operations are performed, the synchronization relationship is automatically maintained without requiring additional user intervention to realign the content.
Solution Approach 2:
The system provides visual feedback through the timeline interface, displaying anchor points and their corresponding positions on both overlay content and video content. This feedback mechanism allows users to verify synchronization status and understand how editing operations will affect the aligned content, maintaining trust in the synchronization reliability.
2Adaptability or versatility
If the video content is edited by removing, adding, or rearranging segments, then the editing flexibility is improved, but the synchronization of overlay content with video content is disrupted
Solution Approach 1:
The anchoring system is designed to be dynamic rather than static. When editing operations modify the video content timeline, the anchor points automatically adjust their positions to maintain the synchronization relationship. The system dynamically recalculates anchor positions based on the current state of video and overlay content, allowing flexible editing while preserving synchronization.
Solution Approach 2:
The anchor point acts as an intermediary element that mediates between the overlay content and video content. It serves as a reference marker that maintains the relationship between the two content types even when their lengths and positions change due to editing operations, enabling flexible modification without losing synchronization.
3Measurement precision
If manual synchronization of overlay content is performed, then the precision of synchronization can be controlled, but the time required for editing operations increases
Solution Approach 1:
The system performs self-service synchronization through automatic anchor point alignment. When overlay content is added to the timeline, the system automatically calculates and establishes the correct anchor points based on the video content's timing information, eliminating the need for manual synchronization adjustments and saving user time while maintaining precision.
Solution Approach 2:
The system performs preliminary synchronization actions by automatically establishing anchor points when overlay content is imported or added to the project. This preliminary alignment is done based on metadata and timing information extracted from the video and overlay files, preparing the content for synchronization without requiring manual intervention during subsequent editing operations.

AI summary
A computer-implemented method includes displaying, within a user interface in a digital media system, a project pane, displaying video content within the project pane, the video content aligned relative to a time line, adding overlay content to the video content, and anchoring a first position in the overlay content to a second position in the video content such that content corresponding to the first position is synchronized to content corresponding to the second position.
