Solution Overview
Problem
Insufficient storage capacity makes it difficult to record and save full-frame videos, necessitating a method to convert full-frame videos into slide videos to reduce file size and create new content formats.
Innovation Solution
A video processing method and apparatus that acquires a slide video by selecting representative frames from input videos, synchronizing them with audio, and dividing the video into sections, which can be based on viewer preferences, audio analysis, or object detection, and includes extracting representative text for inclusion in the slide video.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full-frame video is recorded, then video quality is maintained, but storage capacity is insufficient
Solution Approach 1:
The patent extracts only the essential visual information from full-frame video by selecting representative frames at key moments (scene transitions, important events) while discarding redundant continuous frames. This extraction approach maintains the core visual content and narrative flow while dramatically reducing the data volume requiring storage.
Solution Approach 2:
Instead of storing complete continuous video data, the patent creates a simplified copy consisting of discrete representative frames that capture the essential visual information. This copy approach preserves the ability to review and analyze video content while using minimal storage space, as only key frames rather than all frames are retained.
2Quantity of substance
If slide video is created to reduce file size, then storage capacity is optimized, but video quality is reduced
Solution Approach 1:
The patent applies local quality enhancement by ensuring that each representative frame is of high quality and clearly captures the specific moment or scene it represents. Rather than uniformly reducing quality across all frames, the system selectively preserves high-quality imagery at critical points in the video, maintaining overall perceived quality despite the reduced frame count.
Solution Approach 2:
The system performs preliminary analysis of the video content to identify and select the most important frames before finalizing the slide video. By pre-identifying key moments, scene transitions, and significant visual elements, the system ensures that the reduced-format video retains the essential quality and narrative impact of the original full-frame video.

AI summary
Provided is a video processing method and apparatus. The video processing method includes acquiring an input video including a plurality of video frames and audio frames; dividing the input video into one or more sections; determining a representative video frame from among the plurality of video frames with respect to each of the one or more sections; and acquiring a slide video that includes the representative video frames.
