Format VOB
The VOB (Video Object) format is a type of file developed for DVD-Video, introduced in 1995 by the DVD Consortium (now known as the DVD Forum). These files are essentially multimedia containers based on the MPEG-2 format, specifically designed to organize and store the content of video DVDs.
A VOB file can simultaneously contain several data streams: video, audio (potentially including multiple tracks in different languages), subtitles, and menus. The video is generally encoded in DVD quality with a standard resolution of 720×480 pixels (NTSC) or 720×576 pixels (PAL), while the audio may be in AC-3 or DTS format. This versatility makes it a format particularly suitable for commercial and personal DVDs.
VOB files are typically accompanied by IFO (information) and BUP (backup) files that contain the necessary metadata for DVD navigation, such as chapter structures and playback settings. A peculiarity of VOB is its size limitation to 1 GB, which explains why a movie is often divided into several files (VTS_01_1.VOB, VTS_01_2.VOB, etc.). Although this format remains widely used for DVDs, it has been gradually supplanted by more modern formats such as Blu-ray for high-definition content. VOB file playback is now supported by most media players, although certain copy protection measures may sometimes limit their accessibility.
Format AVI
The Audio Video Interleave format was developed by Microsoft in 1992 as part of their Video for Windows initiative.
This media container allows for the simultaneous storage of audio and video data in a single file, interleaving them for synchronized playback. Its structure, based on the RIFF format, offers great flexibility in the choice of codecs used for compression.
AVI quickly became a video standard in the 1990s and early 2000s, particularly appreciated for its broad compatibility with Windows systems and its ability to maintain high video quality. It supports various resolutions and can contain videos encoded with different codecs like DivX, XviD, or MPEG-2, thus offering significant flexibility to content creators.
Despite its historical advantages, AVI has certain technical limitations. It does not natively support embedded subtitles, chapters, or advanced metadata, and it can struggle with videos over 2 GB due to its indexing structure.
These constraints, combined with the emergence of more modern formats like MP4 and MKV, have gradually reduced its use. Nevertheless, AVI remains widely supported by most media players and continues to be used in certain contexts, particularly for archiving uncompressed videos or compatibility with older systems.
