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 AVI file?

Audio Video Interleave (AVI) is a multimedia container format introduced by Microsoft in 1992 as part of the Video for Windows technology. It adheres to the Resource Interchange File Format (RIFF) specification, storing audio and video data in tagged chunks (specifically 'movi' lists) to allow synchronous playback. While widely compatible, the legacy AVI architecture lacks native support for modern features found in MP4 or MKV, such as variable frame rates (VFR), B-frames, and sophisticated chapter markers. It typically utilizes codecs like DivX, Xvid, or MJPEG.

How to open an AVI file

AVI files enjoy broad compatibility on Windows via Windows Media Player. However, because AVI is a container that can hold various codecs (e.g., DivX, Xvid), playback may fail if the specific codec is missing. macOS users can view AVI files using QuickTime Player if the content is MJPEG, but third-party players are often required for other codecs. VLC media player and MPC-HC are standard recommendations for handling the vast array of codecs potentially encapsulated within an AVI file.
