Clown_BD is a popular, free Windows utility designed to extract the main movie, audio tracks, and subtitles from Blu-ray (BD) and HD DVD content. It serves as a graphical user interface (GUI) that streamlines the complex process of demuxing and remuxing high-definition media files.
The software simplifies home media archiving. It allows users to convert physical discs into digital formats compatible with home media servers and playback devices. Core Features
Main Movie Extraction: Bypasses unnecessary menus, warnings, and special features to isolate just the primary feature film.
Stream Customization: Allows users to pick specific video resolutions, distinct audio formats, and targeted subtitle tracks.
Audio Conversion: Utilizes background tools to transcode or downmix uncompressed HD audio formats into standard formats like AC3 or DTS.
Flexible Output Formats: Formats the final output into a transport stream (TS or M2TS format), a raw Blu-ray structure, or an uncompressed ISO file. Under-the-Hood Architecture
Clown_BD functions as an administrative shell. It automates several command-line utilities through a single interface:
eac3to: The primary engine used to analyze the disc playlists and demux the video, audio, and subtitle streams.
tsMuxeR: The utility responsible for multiplexing the separated tracks back into a cohesive TS, M2TS, or Blu-ray folder structure.
BDSup2Sub: Integrated to handle subtitle conversion, rendering, and processing forced captions. Typical Workflow
Source Selection: Point the software to the extracted Blu-ray folder directory or mounted ISO image on your hard drive.
Playlist Analysis: Clown_BD scans the directory to identify the longest playlist, which normally corresponds to the main movie.
Track Selection: Deselect unwanted audio commentary tracks or foreign subtitles to minimize file size.
Output Generation: Click process to let the program automatically demux, transcode, and package the files into your chosen container format.
