A VOB file (Video Object) is a container format contained in DVD-Video media. VOB is based on MPEG-2 program stream format, but with additional limitations and specifications in the private streams^[1]^[2]. It contains the actual Video, Audio, Subtitle, and Menu contents in stream form.

A player of generic MPEG-2 files can play a VOB file; sometimes one has to change the filename extension from .vob to .mpg or .mpeg so the player recognizes it as MPEG-2. However, most basic MPEG-2 players won't use the subtitle information and other VOB-specific information from the file.

To burn a VOB file to a DVD±R disc, one needs other standard DVD-Video files as well, including IFO and BUP files. The burning is easy with software such as K3b, Nero, Roxio Toast or ImgBurn.

MPlayer, VLC media player, Media Player Classic and more platform-specific players play VOB files.
