I made this script for anime episodes and that's why there is that last option in the above list. It is actually a very versatile & advanced feature and one might want to change it based on their requirements. This option only includes japanese audio streams. All other non-audio streams are included as it is. There is one more thing here though. If the video contains more than one video tracks, then only the first one is included and others are discarded.

Also, this function will directly copy any files whose extensions are either present in the stop word list or if any of the following string is present in the full path of the input file (case-insensitive): -

• /ova >
• /ovas >
• /movie >
• /movies >
• /extra >
• /extras >
• /special >
• /specials >

Files in such paths are called non season files. This direct copy feature for Non Season Files can be turned off using the config.json file.

All file paths are relative to the file paths set in the config.json file.

If output file path is set as * (default), then output path is set to be same as input file path (But in output directory).

If input file path is set as * (default), then the script recursively on files and directories in the base input file path.

This application is based on FFMPEG, so make sure that it is installed on the system and also is set as environment variable on the system.

This script is designed for Windows, but most probably should run fine on other OSs as well. Not sure about MacOS.
