Video Editing Apparatus Exporting Consecutive Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video editing applications face limitations when exporting editing data files, as they require the original video sequence file to be copied in full, leading to excessive data transfer and restricting editing flexibility, especially when the reference range of a clip needs to be expanded.
Innovation Solution
An editing apparatus and method that generate a video sequence file including the specified range and supplementary ranges preceding and succeeding it, allowing for expanded editable regions without the need for repeated exports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the original video sequence is copied and output as is, then the video sequence file can be used by another application, but the quantity of excess data increases
Solution Approach 1:
The patent extracts only the necessary portion of the video sequence (the reference range referred by the clip) and includes it in the exported video sequence file, along with a small margin of data before and after the reference range. This extraction approach reduces the quantity of excess data while maintaining compatibility, as the extracted portion is sufficient for the target application to perform editing operations without requiring the entire original video sequence.
2Quantity of substance
If only the video sequence of the reference range that is referred by the clip is exported, then the data quantity is reduced, but the application cannot perform trimming to expand the reference range
Solution Approach 1:
The patent applies preliminary action by including a margin of video sequence data before and after the reference range in the exported file. This preliminary inclusion of additional data ensures that when the target application needs to perform trimming operations to expand the reference range, the necessary data is already available in the exported file, enabling flexible editing without requiring repeated exports or access to the original video sequence.
3Adaptability or versatility
If the original video sequence is exported in full, then editing flexibility is maintained, but the data transfer size increases excessively
Solution Approach 1:
The patent applies local quality by exporting only the local portion of the video sequence that is relevant to the clip being edited, rather than the entire video sequence. The exported file includes the reference range referred by the clip plus a small margin of data before and after, providing sufficient local quality for editing operations while dramatically reducing the overall data transfer size compared to exporting the complete original video sequence.
4Quantity of substance
If the video sequence file is exported with only the reference range, then data redundancy is reduced, but repeated exports are required for expanded editing
Solution Approach 1:
The patent applies preliminary action by pre-including a margin of video sequence data before and after the reference range in the exported file. This preliminary inclusion ensures that when the target application needs to perform trimming operations to expand the reference range, the necessary data is already available in the exported file, eliminating the need for repeated exports and saving time while maintaining low data redundancy.

AI summary
An editing apparatus for an editing video sequence that includes an editing unit for setting a first range to one part of the video sequence; a video sequence file generating unit for generating a video sequence file including video sequence corresponding to the first range and video sequence corresponding to a second range, within the second range is consecutively preceding to and/or subsequent to the first range; and an output for outputting the video sequence file.
