Video Editing Apparatus Automatic In-Point Out-Point Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nonlinear video editing systems face challenges in quick editing during live events like sports telecasts, where delays in editing can distract viewers and require repetitive processing of video clips for later use.
Innovation Solution
An editing apparatus and method that automatically sets reference points during playback, allowing for simultaneous generation of video clips from the edited section, eliminating the need for separate in-point and out-point settings and reducing editing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual in-point and out-point setting is performed during video playback, then editing precision is improved, but editing time increases and productivity decreases
Solution Approach 1:
The system automatically detects and sets the in-point when playback starts, and automatically detects and sets the out-point when playback ends. This self-service mechanism eliminates the need for manual reference point setting while maintaining precise editing boundaries, thereby resolving the contradiction between editing precision and productivity
Solution Approach 2:
The system pre-establishes the in-point automatically at the moment playback begins, without requiring prior manual intervention. This preliminary automatic action ensures precise start point detection while saving time that would otherwise be spent on manual setting
2Measurement precision
If video data is replayed and re-clipped for later broadcasting, then editing precision is improved, but time consumption increases
Solution Approach 1:
The system creates a virtual copy of the video section between in-point and out-point through editing information storage, without requiring physical re-clipping or replaying of the original video data. This virtual copying mechanism preserves editing precision while eliminating time-consuming replay operations
Solution Approach 2:
The system performs the clipping operation in advance by storing editing information that defines the in-point and out-point boundaries. This preliminary action allows the same video section to be reused for later broadcasting without requiring actual replay and re-clipping, thus saving time while maintaining precision

AI summary
Herein disclosed are an editing apparatus, an editing method, and an editing program allowing quick editing of video data. In order to clip a section in the video data and play it to be broadcasted as a replay, receiving a request to start playback from a desired position, an in-point is set in response to the request, and an out-point is set in response to a request to finish playback. Then, other video data from the video data of a section between the in-point and the out-point is generated.
