Video Recording Method for Personalized Annotation Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video recording technologies on mobile terminals only record the content currently played, failing to meet users' personalized needs for recording specific moments during video playback.
Innovation Solution
A method that involves taking screenshots and performing image conversions during video playback to acquire frame images, which are then superimposed with edited images to generate a recorded video clip, synchronizing with the audio stream to create a personalized video recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If screen recording technology is used to record currently played content, then the recording function is achieved, but the content is completely consistent with the played content and cannot meet personalized user needs
Solution Approach 1:
The patent segments the video content into multiple layers: the original video content layer and the user annotation layer (drawings, text, emojis). This segmentation allows independent processing of each layer, enabling personalized recording without significantly increasing overall system complexity. The editing panel and annotation tools are added as separate modular components that can be toggled on or off.
Solution Approach 2:
The patent merges the original video content with user annotations by superimposing the annotation layer over the video frames. This combining creates a new integrated video clip that contains both the original content and personalized markings, achieving adaptability while maintaining reasonable system complexity through efficient image processing.
2Adaptability or versatility
If multiple image processing operations are performed during video playback, then personalized video clips can be generated, but the processing time and computational resources increase
Solution Approach 1:
The patent performs screenshot operations and captures user annotations during the video playback process itself, rather than after playback completes. This preliminary action allows the system to capture annotations in real-time as users create them, reducing post-processing time and enabling faster generation of personalized video clips.
Solution Approach 2:
The patent creates simplified copies of video frames with annotations overlaid, rather than performing complex transformations on the original video data. By working with frame-by-frame images and superimposing annotation layers, the system reduces computational complexity and processing time compared to traditional video editing methods.
