Screen Recording of Video Areas Without Manual Region Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen recording methods require high user operation costs and generate large data volumes due to manual selection of recording areas, leading to storage pressure and inefficiency.
Innovation Solution
A screen recording method that automatically records specific content areas based on the current display, using application and view whitelists to determine recording regions, reducing the need for manual selection and minimizing data volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual selection of recording area is used, then recording flexibility is improved, but user operation costs increase
Solution Approach 1:
The system automatically detects and records the video playing area without requiring user intervention. The video note application autonomously identifies the video content area and performs recording, eliminating the need for manual area selection while maintaining recording flexibility through automatic adaptation to different video layouts.
2Reliability
If entire screen recording is performed, then recording completeness is improved, but data volume increases
Solution Approach 1:
The system extracts and records only the video playing area from the entire screen, separating the relevant content from unnecessary elements. By identifying the video content boundaries and recording only that specific region, the system maintains recording completeness for video content while significantly reducing the overall data volume compared to full-screen recording.
3Measurement precision
If manual area selection is required, then recording precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically performs area detection and selection by identifying video playing areas through content analysis. This self-service approach achieves precise area selection without requiring user interaction, thereby maintaining measurement precision while dramatically improving ease of operation by eliminating manual selection steps.
4Ease of operation
If automatic area detection is used, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The video note application integrates multiple functions including video playback, area detection, and recording within a single system. By making the application multi-functional, the system achieves automatic area detection without requiring separate complex subsystems, thereby improving ease of operation while controlling device complexity through functional integration.

AI summary
This application provides a screen recording method and an electronic device. The method includes: displaying a first interface of a first application, where the first interface includes a first area and a second area, the first area is a video playing area, and the second area is a non-video-playing area; in response to a first tap/click operation on a start recording button, recording, by using a video note application, display content corresponding to the first area; in response to a first tap/click operation on an end recording button, ending recording to obtain a first video; in response to a first user operation, displaying a second interface of the first application, where the second interface does not include a video playing area.
