Video Slide Generation Using Time Axis Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating video slides from pictures are cumbersome and lack visual clarity, making it difficult for users to conveniently set playing effects, especially when dealing with a large number of images.
Innovation Solution
A method and device that utilize a time axis to visualize the sequence of pictures, allowing users to easily select and adjust the order and duration of image playback, along with adding music and text elements, to generate video slides with customizable playing effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users manually set playing sequence and effects for each picture one by one, then tailored requirements can be satisfied, but the operation becomes complicated and time-consuming when there are a large number of pictures
Solution Approach 1:
The patent segments the picture sequence into discrete units that can be individually manipulated on a time axis. Each picture becomes an independent element that can be dragged, dropped, and reordered, transforming a complex global editing task into manageable local operations. This segmentation allows users to work with individual pictures rather than managing entire sequences at once, significantly reducing operational complexity.
Solution Approach 2:
The patent introduces a time axis as an intermediary interface between the user and the picture sequence. This visual mediator provides intuitive controls for sequencing and timing, allowing users to manipulate picture playback through drag-and-drop operations and visual timeline adjustments rather than complex parameter settings. The time axis serves as a buffer that simplifies the interaction model while maintaining full control over playback effects.
2Productivity
If traditional picture combining methods are used, then pictures can be combined rapidly, but the presented effect is static and user experience is relatively poor
Solution Approach 1:
The patent transforms static picture combination into a dynamic video slide process. Instead of merely arranging pictures in fixed positions, the system enables temporal sequencing with adjustable playback durations, transitions, and effects. The time axis interface allows real-time modification of playback timing and sequence, creating dynamic visual presentations that adapt to user preferences while maintaining rapid operation through intuitive drag-and-drop controls.
3Adaptability or versatility
If users need to set playing sequence for each picture individually, then customized video slides can be generated, but the process becomes cumbersome especially with large numbers of images
Solution Approach 1:
The patent automatically performs preliminary actions by default-sequenceing pictures upon import and pre-configuring the time axis structure. This preliminary organization eliminates the need for users to manually sequence each picture from scratch, providing a ready-to-use framework that can be quickly adjusted. The system performs initial sorting and timing setup automatically, reducing setup time while preserving full customization capability through subsequent user adjustments.
