Video Editor Transition Region Overlap and Splicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video editors are cumbersome and misleading in representing transitions between video clips, making it difficult for users to select and apply edit operations due to the occlusion of transition symbols with clip selectors and the concentration of selectable items in a small display area.
Innovation Solution
A video editor application that allows users to create transitions by overlapping video clip segments on a single editing track, displaying spliced ends with visual aids and selectors to facilitate trim operations, and enabling selective display of transition effects such as fading, scrolling, or dissolving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a transition symbol is overlaid on abutting video clips to indicate a transition region, then the transition can be visually represented, but the transition symbol occludes the tail selector of the first clip and head selector of the second clip, making it difficult to view and select attributes
Solution Approach 1:
The patent extracts the transition representation from the traditional overlay symbol approach and separates it into distinct visual elements: the transition region is shown as an overlapping area between clips, while selectors remain visible and accessible at the edges of the clips. This extraction eliminates the occlusion problem while maintaining transition indication.
Solution Approach 2:
The transition region is segmented from the clip selectors in the visual representation. The overlapping region clearly delineates the transition area, while head and tail selectors are positioned separately at the clip boundaries, allowing both transition indication and attribute selection to coexist without interference.
2Area of stationary object
If multiple selectable items (transition symbol, head selector, tail selector) are packed into a small display region, then the interface remains compact, but it becomes difficult for users to select and apply edit operations
Solution Approach 1:
The patent utilizes the time dimension by allowing clips to overlap in the timeline view, creating a two-dimensional representation where spatial arrangement indicates temporal relationships. This dimensional approach distributes selectable items across a larger visual area while maintaining logical organization, improving accessibility without significantly increasing the display region.
Solution Approach 2:
Different regions of the display are assigned different qualities: the overlapping transition region has a distinct visual appearance to indicate its special status, while selectors maintain their standard appearance and positioning. This local differentiation allows users to easily distinguish between transition indicators and selectable attributes, improving operation ease without expanding the overall display area.
3Stability of the object's composition
If users must temporarily remove and reapply transition symbols to modify transitions, then the transition structure is preserved, but additional commands and steps are required, making the process time-consuming
Solution Approach 1:
The system provides self-service functionality where users can directly modify transition regions by selecting and dragging the overlapping area or its boundaries. The transition structure automatically adjusts when clips are modified, eliminating the need to manually remove and reapply transition symbols while preserving transition integrity.
Solution Approach 2:
The transition region is represented as a dynamic, selectable area that can be directly manipulated. Users can adjust transition parameters by interacting with the overlapping region itself rather than through complex symbol manipulation, allowing real-time modification while maintaining the transition structure through automatic updates.

AI summary
A respective user modifies (e.g., selects, drags, and drops) either one or both of a first visual representation of a first video clip segment and second visual representation of a second video clip segment to overlap with each other in order to create a so-called transition region while in an editing phase. In response to creating the overlap, a respective video editor application herein splices respective ends of the first visual representation and the second visual representation to indicate where respective first and second content overlap with each other. For example, to more clearly depict the spliced ends of content on a respective display screen, the video editor application initiates display of an overlapping content region to include a first region in which the first content appears to be overlaid on the second content and a second region in which the second content appears to be overlaid on the first content.
