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

VSEngineering 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

Engineering Contradiction:
Improveediting process complexityVSAvoidvideo playback stability
Core Design Contradiction:
Device complexityVSReliability

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improveediting efficiencyVSAvoidvideo and visual element synchronization
Core Design Contradiction:
ProductivityVSStability of the object's composition

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improvesystem operation simplicityVSAvoidvideo editing efficiency
Core Design Contradiction:
Ease of operationVSProductivity

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.

Inventive Principle:
Principle #15Dynamics
