In-App Video Editing With Dual Players for Refresh-Rate Jitter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video editing applications face issues such as video lag and jitter due to mismatched refresh frequencies between video and visual elements, leading to inefficient editing processes.
Innovation Solution
Utilizing two separate players to independently manage the playback of video and visual elements, allowing them to operate at their respective frequencies without interference, thereby reducing lag and jitter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If video and visual elements are edited together in a single player, then the editing process is simplified, but video lag and jitter occur due to refresh frequency conflicts
Solution Approach 1:
The player is divided into two independent sub-players: a video player for playing video content and a visual element player for playing visual elements. Each sub-player operates with its own refresh frequency independently, avoiding conflicts between video and visual element rendering. This segmentation resolves the contradiction by maintaining playback stability while keeping the editing interface unified.
2Productivity
If video and visual elements are played at different refresh frequencies, then each element can be optimized for its specific requirements, but synchronization problems and jitter occur
Solution Approach 1:
The solution introduces a new dimension of control by separating the refresh frequency management into independent dimensions for video and visual elements. Instead of forcing a single refresh frequency on both, the system allows each to operate at its optimal frequency in its own dimension, eliminating synchronization conflicts while maintaining editing efficiency.
3Ease of operation
If the user cannot independently control video playback and visual element playback, then the system is easier to operate, but editing efficiency decreases
Solution Approach 1:
The system provides dynamic control capabilities where users can independently adjust playback settings for video and visual elements based on their specific needs. The interface adapts to different editing scenarios, allowing users to control each element's playback speed, timing, and synchronization according to the requirements of different editing tasks, thereby improving editing efficiency while maintaining ease of operation.
