Video Editing Frame Visualization for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video editing on smart mobile terminals lacks an intuitive method to select and visualize the duration of video segments for editing, leading to increased error rates and reduced efficiency in limited screen space.
Innovation Solution
A method and apparatus for video editing that allows users to select frame images indicating video segment duration in a showing area, with rendering scripts highlighting these images, enabling intuitive selection and storage of video segments in separate storage areas for editing and manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video editing is performed on smart mobile terminals with limited screen space, then portability and accessibility are improved, but the precision of video segment selection and visualization deteriorates due to insufficient display area
Solution Approach 1:
The video is segmented into discrete frame images that are displayed in the showing area. Each frame image represents a specific time point or duration of the video, allowing users to select video segments by choosing individual frames or ranges of frames. This segmentation enables precise video segment selection on mobile devices with limited screen space.
Solution Approach 2:
The patent introduces a temporal dimension to the display by showing frame images that represent different time points of the video. The showing area displays frames arranged in temporal sequence, and users can select video segments by specifying start and end frames, thereby adding time-based precision to the selection process despite limited spatial display area.
2Measurement precision
If the showing area displays detailed video segment information, then selection accuracy is improved, but the available screen space for other editing functions is reduced
Solution Approach 1:
Instead of displaying the actual video content in the showing area, the patent uses frame images (copies or representations of video frames) to indicate video segment duration. These frame images serve as visual proxies that convey temporal information without requiring the full video display area, thus preserving screen space for other editing functions while maintaining selection accuracy.
Solution Approach 2:
The patent employs visual rendering of frame images with different colors or highlights to indicate selected video segments. By using color changes and visual cues on the frame images, the system conveys detailed selection information efficiently within limited space, allowing users to identify video segment boundaries and duration without requiring extensive display area.
3Adaptability or versatility
If multiple video segments are managed simultaneously in memory, then editing flexibility is improved, but the memory consumption and processing complexity increase
Solution Approach 1:
The patent pre-loads and stores frame images in the showing area before user selection. By preparing the visual representation of video segments in advance, the system enables users to perform multiple editing operations on different segments without requiring complex real-time processing, thus improving editing flexibility while managing memory usage efficiently through advance preparation.

AI summary
Disclosed are a method, an apparatus and a smart mobile terminal for editing a video. The method includes: acquiring an editing instruction to be executed of a user; selecting frame images which indicate a duration of a video segment in a preset showing area based on the editing instruction; storing the video segment in a preset second storage area; storing a reserved video segment in a preset first storage area; rendering the frame images by invoking a preset rendering script for highlighting the frame images in the showing area; retrieving frames of the reserved video segment sequentially based on a preset first time span; determining scaled frames based on a preset scaling proportion and the frames; and arranging the scaled frames in the showing area sequentially in an order of retrieving for displaying frame images which indicates a duration of the reserved video segment in the showing area.
