Video Annotation System With Automatic Time Stamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the movie and audio/video production industry, directors face challenges in providing clear editing instructions for audio/video clips, as written or typed notes often lack accurate time notations, leading to misunderstandings and costly editing mistakes.
Innovation Solution
A system that allows users to annotate digital clips with textual, auditory, or graphical elements, setting specific durations for each annotation, and provides a graphical user interface for entering, editing, and saving annotations, which can be displayed or hidden during playback, and saved as metadata or separate files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If written or typed instructions are used without accurate time notations, then the notes are simpler to create, but misunderstandings and editing mistakes increase
Solution Approach 1:
The system automatically captures time information in advance by detecting when annotations are added to specific video frames, eliminating the need for manual time notation entry. This preliminary automatic action ensures accurate time stamps are recorded without requiring the annotator to manually note the time, thus maintaining ease of use while improving reliability.
2Reliability
If manual time notations are added to instructions, then accuracy of instructions improves, but the complexity of annotating increases
Solution Approach 1:
The system performs self-service by automatically generating time stamps and frame references when annotations are added. The computer vision system autonomously identifies the current video frame and captures its time information, eliminating the need for manual time notation entry. This self-automating approach maintains accuracy while reducing the complexity burden on the annotator.
3Reliability
If meticulous time notations are recorded, then editing mistakes are avoided, but the time required for annotating increases
Solution Approach 1:
The system replaces the mechanical process of manual time notation entry with an automated computer vision system. The software automatically captures frame time stamps and video metadata, substituting manual writing operations with automated digital detection and recording. This substitution maintains meticulous accuracy while dramatically reducing the time required for annotation.
4Loss of information
If annotations are displayed during playback, then communication of instructions is enhanced, but the visibility of the video clip may be reduced
Solution Approach 1:
The system applies local quality by positioning annotations in specific regions of the video frame where they provide information without obscuring the main video content. Annotations are placed strategically to enhance instruction clarity while maintaining video visibility, allowing both the video and annotations to be effectively perceived simultaneously.
Data Source
AI summary
A method of annotating a digital clip and setting a duration over which the annotation applies is disclosed. The method provides a graphical user interface (GUI) with a display area for displaying the digital clip. The GUI provides controls for entering notes, including graphical notes, on the clip. The GUI also provides controls for setting the duration for which the annotation applies.
