Open VOBU File
VOBU, which stands for Video Object Unit, is a data container found on DVDs containing MPEG video streams. Navigating through a DVD, fast-forwarding, rewinding, pausing, and otherwise controlling is all done through the control of VOBU. In this article, we will drive deep into the possible formats and ways to open or use files with the VOBU file extensions.
Understanding VOBU File Format
A VOBU essentially includes 0.4 to 1.2 seconds of DVD video content. When you're seeking or changing chapters in a DVD player, you've seen the VOBU file system in action. It's how the DVD knows where to go and how much data to play from the MPEG-2 data stream. VideoHelp Glossary provides detailed information on the structure of VOBU.
Opening VOBU Files
Since VOBU files are part of a larger DVD Video Object (VOB) system, they are not typically interacted with directly by users. When playing a DVD, the devices handle VOBU files internally but do not allow direct opening or editing of these files. However, if you're interested in DVD encoding or re-authoring, various tools can allow you to manipulate VOBU files indirectly. Tools like DVDShrink or FFmpeg can provide capabilities to compress, convert or stream digital video and audio in various formats.
VOBU File Extension Usage in DVD Error Detection
Other common uses of VOBU lie within DVD error detection and recovery. When a DVD player encounters problems with reading a disc, it can skip to the next VOBU, making errors less noticeable. Softwares such as dvdisaster can provide additional analysis and create error correction files.
VOBU File Important Information
In conclusion, VOBU is a specialized file format, strictly connected with the system of DVD Video Objects (VOB). They are heavily involved in the smooth performance of DVD video playback, chapter transitions, and error handling. Both DVD players and authoring software deal with VOBU files internally. While the average user does not generally need to interact with VOBU files directly, professionals in DVD authoring or data recovery find their understanding and knowledge of VOBU indispensable.
