Real-Time Audio-Video Synchronization Editing Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video creation software requires users to pre-determine the duration and order of still images, making it complex and prone to audio-video desynchronization, especially for non-professionals.
Innovation Solution
A system and method for creating video content by synchronizing digital still images with a digital audio track using a two-key interface, allowing real-time adjustment of image duration and order inspired by music, along with Multi-Frame Generator Filters to generate procedural variations of images, facilitating intuitive audio-visual synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If users pre-determine the duration and order of still images through complex editing operations, then the video can be created with structured content, but the process becomes tedious and audio-video synchronization becomes difficult for non-professionals
Solution Approach 1:
The system transitions from static pre-determined image durations to dynamic real-time duration assignment. Users can adjust the duration of each image on-the-fly during playback by simply pressing the record button, allowing the duration to be determined dynamically based on actual audio-video synchronization needs rather than being fixed in advance through complex editing operations
Solution Approach 2:
The system enables users to perform audio-video synchronization themselves through an intuitive interface. By allowing direct duration adjustment during playback with a single button press, the system empowers non-professionals to achieve precise synchronization without requiring complex editing skills or time-consuming pre-planning
2Ease of operation
If users specify the duration of each image before recording the video, then the video structure is predetermined, but the user cannot adjust durations in real-time during the creative process
Solution Approach 1:
The interface transforms from requiring pre-determined static duration settings to enabling dynamic real-time duration adjustments. Users can change the duration of each image during playback by simply pressing the record button at the desired moment, making the system adaptable to creative decisions made in the moment rather than requiring complex pre-planning
Solution Approach 2:
Instead of requiring users to set durations before playback (traditional approach), the system inverts the workflow by allowing duration determination during playback. This reversal simplifies the interface by eliminating complex pre-editing requirements and enabling intuitive real-time control through a single button press
3Quantity of substance
If the number of still images is increased from digital photography, then more visual content is available for video creation, but selecting and ordering images becomes more complex and time-consuming
Solution Approach 1:
The system transitions from requiring static image selection and ordering before video creation to enabling dynamic image sequence adjustment during playback. Users can change the order and duration of images in real-time by pressing the record button, allowing efficient work with large image collections without the need for time-consuming pre-selection and ordering processes
Solution Approach 2:
The system enables users to independently manage and adjust image sequences without requiring complex editing operations. By allowing direct manipulation of image duration and order during playback through a simple button press, the system makes it efficient to work with large numbers of images while maintaining full creative control
