Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current video editing software lacks effective tools for creating a soundtrack that matches the changing emotions and scenes in a video, resulting in a misfit between the soundtrack and the video content, which diminishes the overall impact of the video experience.

Innovation Solution

A system and method for automatically creating an emotion-controlled soundtrack by allowing users to place emotion-type identifier tags within the video work, which are used to algorithmically generate a soundtrack that matches the video's content, using a database of music loops and tags to create a seamless audio track.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If rudimentary audio editing tools are provided in video editing software, then ease of operation is improved, but the quality and effectiveness of soundtrack creation deteriorates

Engineering Contradiction:

Improveease of operationVSAvoidsoundtrack quality

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The system automatically generates the soundtrack by analyzing video content and selecting appropriate music clips from a database, eliminating the need for users to manually edit audio tracks while maintaining professional-quality soundtracks that match the video's emotional tone and pacing

Inventive Principle:

Principle #25Self-service

2Device complexity

If a single global emotion parameter is used for soundtrack generation, then device complexity is reduced, but the precision of matching changing video content deteriorates

Engineering Contradiction:

Improvesystem complexityVSAvoidsoundtrack-video match precision

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The soundtrack generation process is divided into multiple segments corresponding to different video clips or scenes. Each segment is independently analyzed for emotional content and matched with appropriate music clips, allowing the system to capture emotional transitions and variations throughout the video without requiring an overly complex unified model

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If automated soundtrack generation is implemented, then ease of operation is improved, but the ability to handle complex emotional transitions deteriorates

Engineering Contradiction:

Improveease of operationVSAvoidemotional transition accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system incorporates feedback mechanisms where users can review the generated soundtrack, provide corrections, or adjust emotional parameters for specific segments. This feedback loop allows the automated system to learn from user inputs and improve its ability to accurately handle complex emotional transitions in subsequent generations

Inventive Principle:

Principle #23Feedback

AI summary

There is provided herein a system and method for enabling a user of digital video editing software to automatically create an emotionally controlled soundtrack that is matched in overall emotion or mood to the scenes in the underlying video work. In the preferred arrangement, the user will be able to control the generation of the soundtrack by positioning emotion tags in the video work that correspond to the general mood of each scene. The subsequent soundtrack generation step will utilize these tags to prepare a musical accompaniment to the video work that generally matches its on-screen activities.
