FAQ

A: Audio formats such as MP3, WAV, AAC, FLAC, OGG, M4A, and WMA are supported, as well as video formats such as MP4, AVI, MOV, MKV, WMV, FLV, WEBM, and M4V.

A: The tool reads the duration from media file metadata, and regular files usually return accurate results. If a file is corrupted, has abnormal encoding, or is missing metadata, the duration may be shown as unknown.

A: The tool supports selecting multiple files in batches. When there are many files, the interface only previews the first 20, while analysis and packaging will process the selected files; if the files are large, it is recommended to process them in batches.

A: In “Filter Settings,” select “Duration Range” and enter the start duration and end duration. For example, to filter assets from 1 to 5 minutes, set the start to 00:01:00 and the end to 00:05:00.

A: A single file will be downloaded with its original file name; when multiple files are packaged, the original file names will be preserved. If duplicate names occur, a number will be appended to the file name to avoid overwriting.

A: The exported file includes the file name, media type, format, file size, duration in seconds, formatted duration, and recognition status, making it easy to organize an asset list or continue with statistics.
