What is a VOB file?

The VOB (DVD-Video Object) format is a container format used in DVD-Video media, strictly compliant with the MPEG-2 Program Stream standard (ISO/IEC 13818-1). Located within the VIDEO_TS directory of a DVD, a VOB file multiplexes MPEG-2 video streams, audio streams (formats including Linear PCM, AC-3, or DTS), and subtitle streams (subpictures) into a single datastream. The format supports copy protection via the Content Scramble System (CSS) and functions as the core delivery mechanism for standard-definition digital video on optical discs.

How to open a VOB file

VOB files are natively supported by standalone DVD players and computer software designed for DVD playback, such as CyberLink PowerDVD. On standard operating systems without dedicated DVD software, the format can be opened using the VLC media player, GOM Player, or MPC-HC, which contain the necessary MPEG-2 decoders. Users may need to open the associated IFO files to navigate menus properly rather than playing raw VOB segments.

What is an MP4 file?

MPEG-4 Part 14 (MP4) is a digital multimedia container format defined by ISO/IEC 14496-14. Based directly on the QuickTime File Format (QTFF), it allows for streaming over the Internet and is the global standard for video compatibility. An MP4 file can store video streams (encoded with H.264/AVC, H.265/HEVC, or MPEG-4 Visual), audio streams (typically AAC or MP3), subtitles, and still images. It utilizes object-oriented structures specifically designed to support initial object descriptors (IOD) and other MPEG features.

How to open an MP4 file

MP4 is the most widely supported video format in existence. It opens natively on virtually all modern operating systems including Windows (via Movies & TV or Windows Media Player), macOS (QuickTime), Android, and iOS. Web browsers (Chrome, Firefox, Safari) also support native MP4 playback via the HTML5 video tag. No external software is generally required, though VLC Media Player is useful for MP4 files containing obscure codecs.
