Video File Naming for Fast End-Clip Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing systems struggle to efficiently specify the end file in a series of divided video files recorded over a long period, leading to difficulties in quickly finding desired video files and combining them for editing, as file names do not adequately indicate the start and end of recording.
Innovation Solution
A video processing apparatus and method that generates file names for partial video files including temporal ordinal numbers and character strings representing the end of recording, allowing easy identification of the end file among a series of divided video files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If video files are periodically divided and recorded for long periods, then the recording duration increases, but the number of files becomes enormous making it difficult to find desired files quickly
Solution Approach 1:
The patent segments the recording period into multiple continuous recording periods, each with its own sequential file numbering. This allows files to be organized by recording period rather than using a single continuous numbering system, making it easier to locate files from specific time periods without searching through all files.
Solution Approach 2:
The patent adds a new dimension to file naming by incorporating recording period identifiers alongside sequential file numbers. This creates a hierarchical file identification system where files can be located by both period and sequence, dramatically reducing search time in large file sets.
2Ease of operation
If file names include only sequential numbers, then the start file can be specified, but the end file cannot be specified when recording is repeated
Solution Approach 1:
The patent divides the file identification system into two segments: recording period identifiers and sequential file numbers within each period. This segmentation allows both start and end files to be specified by combining period information with sequence numbers, enabling complete range selection.
Solution Approach 2:
The patent performs preliminary action by pre-identifying recording periods and assigning them distinct identifiers before files are created. This allows users to later specify file ranges by combining period identifiers with sequence numbers, making end file specification possible without analyzing file contents.
3Measurement precision
If metadata is analyzed to specify the end file, then accurate identification is possible, but it takes a long time to open and analyze files
Solution Approach 1:
The patent extracts the recording period identification information from metadata and incorporates it directly into file names. This extraction allows end files to be identified through file name matching rather than metadata analysis, eliminating the time-consuming file opening and parsing process while maintaining accurate identification.

AI summary
A video processing apparatus which generates a video file from a video obtained by an image capturing unit, and includes a file generation unit that divides, into a plurality of time-series partial videos, in accordance with a set division condition, a video captured during a period from when a begin recording instruction is received until a stop recording instruction to stop the recording is received, and generates each partial video file. In a case of generating each partial video file, the file generation unit generates a partial video file having a file name including information representing a temporal ordinal number, and with respect to an end partial video at a temporal end among the plurality of partial videos, the file generation unit generates a partial video file having a file name including information representing a temporal ordinal number and a character string representing an end.
