Integrated Video Recording With Event Clips and Live Annotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video recording systems face challenges in efficiently organizing and managing large volumes of video content, particularly when users are interested in specific segments of recordings that are not chronologically adjacent, and in handling interruptions during recording, as well as adding annotations to video frames.
Innovation Solution
A video recording system with features for creating live clips, event labeling, and automatic pause/resume functions, along with real-time annotations, to simplify the organization and management of video content and handle interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If video files are organized using conventional file systems with folders and chronological sorting, then files can be stored and accessed, but finding specific video segments becomes time-consuming and inefficient
Solution Approach 1:
The patent segments a continuous video recording into multiple clip files based on detected events or user-defined parameters. Each clip represents a meaningful portion of the original recording, allowing users to access specific segments without browsing through the entire video or manually editing it. This segmentation transforms one large video file into multiple smaller, purposefully organized clip files.
Solution Approach 2:
The system performs preliminary action by automatically creating and organizing clip files during or immediately after the recording process. Event detection algorithms analyze the video content in real-time or during post-processing to identify significant moments, automatically creating clip boundaries without requiring user intervention later. This preliminary organization eliminates the need for manual video editing and makes specific segments readily accessible.
2Adaptability or versatility
If duplicate copies of video files are created to store the same content in multiple folders for different categories, then files can be organized by multiple themes, but storage space is doubled
Solution Approach 1:
Instead of duplicating entire video files across multiple folders, the patent segments the video into clip files and organizes these segments into different categorical groupings. A single clip file can belong to multiple categories through metadata tagging, allowing versatile organization without physical duplication of video data. This reduces storage requirements while maintaining multi-categorical accessibility.
Solution Approach 2:
The patent implements a universal file organization system where clip files serve multiple functions simultaneously. Each clip can be associated with multiple categories, events, or contexts through metadata, allowing the same video segment to be accessed from different organizational perspectives without creating duplicate copies. This multi-functionality enables flexible categorization while conserving storage space.
3Reliability
If video recording continues in the background during smartphone interruptions, then no valuable moments are missed, but the recording contains unwanted segments that require later editing
Solution Approach 1:
The system performs preliminary action by detecting interruptions during recording and automatically pausing the video capture at these moments. Event detection algorithms monitor for smartphone usage patterns, notifications, or camera movement that indicate user distraction, and automatically create pause points in the recording. This preliminary intervention prevents unwanted segments from being recorded in the first place, eliminating the need for later manual editing to remove these portions.
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously monitors recording conditions and adjusts operation accordingly. When interruptions are detected, the system provides feedback by automatically pausing or stopping the recording, and when recording conditions improve, it can automatically resume. This closed-loop control maintains recording reliability while preventing the capture of unwanted segments, reducing the complexity of post-processing.
4Ease of operation
If a video recording is automatically stopped when user engages another app, then unwanted segments are avoided, but valuable seconds are lost when user must navigate back to resume recording
Solution Approach 1:
The system performs preliminary action by detecting when the user returns from another application and automatically resuming the video recording before the user needs to manually restart it. The system monitors for app-switching events and, upon detecting user return, automatically continues the recording from the pause point. This preliminary resumption action eliminates the time loss associated with manual navigation and button pressing, while the automatic pause function continues to prevent unwanted segments from being recorded.

AI summary
A mobile-app based video recording system that allows a user to apply live annotations to video footage by either drawing or typing on top of the footage in an image frame area of a display. A user can choose from a variety of options for the appearance of drawn and typed annotations, including the color, opacity, and stroke width of drawing marks and font, text size, and text and background/textbox colors for typed text, as well as positioning the marks and text as desired. The annotations are recorded and merged with the footage in real time to create an annotated video file. The annotations can also be stored in a separate editable file or in an editable layer of the annotate video file.
