What is it?
VOB (Video Object) is the container format used on standard DVD-Video discs. VOB files are stored in the VIDEO_TS folder of a DVD and contain the actual video, audio, subtitles, and navigation data for the disc. Introduced with the DVD specification in 1996, VOB uses MPEG-2 video encoding and supports Dolby Digital (AC-3) and DTS audio tracks along with subtitle streams.
A typical DVD movie is split into multiple VOB files, each limited to approximately 1 GB to comply with the DVD filesystem (UDF/ISO 9660) specifications. The first file (VIDEO_TS.VOB) contains menu data, while numbered files like VTS_01_1.VOB, VTS_01_2.VOB contain the main feature film. VOB files are closely related to MPEG-2 Program Streams and can often be played directly by media players that support DVD video.
