VOB (Video Object) is a digital video file format used for storing video and audio data on DVDs. It is a container format that can contain multiple video and audio streams, subtitles, and other data related to DVD content.
VOB files typically contain MPEG-2 compressed video data and can be played back on DVD players and on many media players using compatible codecs. The format also supports additional DVD features like menus and chapters, making it well-suited for creating DVD video discs.
VOB files can be converted to other video file formats like MP4 or AVI using compatible media conversion software, and can also be edited using compatible video editing software.
Overall, VOB is a useful video file format for storing and distributing video content on DVDs, particularly for commercial DVD video discs. However, it is not as widely used as more modern video file formats like MP4 or MOV for digital video content distribution.
