Segmented Video Recording for Mobile Jitter Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Long video recording sessions on mobile terminals lead to user fatigue, resulting in jitter and mistakes, which increase the costs of later video editing due to numerous errors in recorded videos.
Innovation Solution
A video recording method and device that generates a video stream segmented into frame sequence segments, allowing for editing and uploading of these segments to a server, reducing the occurrence of jitter and mistakes, and thus lowering the costs of post-processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If video recording time is extended to capture more content, then the duration of recorded video increases, but user fatigue increases leading to more jitter and mistakes
Solution Approach 1:
The patent divides a long video recording into multiple short clips automatically detected through scene change analysis. When a scene change is detected, the system automatically cuts the video at that point, creating separate segments. This segmentation reduces the continuous recording duration that causes user fatigue while preserving all important content through automatic scene transition detection.
2Loss of information
If video recording is continuous to maintain completeness, then all content is captured, but editing costs increase due to numerous errors requiring correction
Solution Approach 1:
The system performs preliminary scene change detection and automatic video cutting during the recording process itself, before post-production editing is needed. By automatically identifying scene transitions and creating cut points in real-time, the system prepares the video structure in advance, eliminating the need for manual review and correction of jitter and mistakes during later editing phases.
3Duration of action of moving object
If user switches hands to relieve fatigue during long recording, then recording can continue longer, but operational mistakes increase
Solution Approach 1:
The system makes the video editing process self-service by automatically detecting scene changes and performing cuts without requiring continuous user intervention. The automatic scene change detection algorithm independently identifies transition points and executes cuts, freeing the user from the need to manually monitor and control the recording throughout long durations.

AI summary
Embodiments of the present application provide a video recording method and device. The method includes: receiving, by an application of a mobile terminal, a video recording instruction of a user; generating, according to a photographing scene, a video stream that can be edited according to segments, the video stream including at least one frame sequence segment; and uploading the edited video stream to a server. According to the present application, by generating a video stream consisting of at least one frame sequence segment during video recording, where the generated video stream can be edited according to segments, the error tolerance of video capture is improved, and the costs of later video editing are reduced.
