The BUP Format
A BUP file is a file from a DVD movie. A DVD movie may contain data for the DVD players and additional data that can be read on a computer. DVD movies have a hierarchical organization of directories, containing video and audio data. It is usually based on the following structure:
The main directory named VIDEO_TS ( Video Title Sets)
contains the video files. The AUDIO_TS
folder is required by some DVD players. Cover_P
contains the cover images of DVD. The DVD may contain additional directories, containing data that can be read on a PC.
A number of elements are present in the VIDEO_TS
- Video manager (VMG). The VMG generally contains introductory videos and the menu giving access to other video tracks (including sub - menus).
- One or more video title sets, containing the video titles.
The "Video Title

" ( VOBs - Video Object Block Sets), each comprising of:
- A "control file" (called VTSI - Video Title Set Information) containing navigation data .
- One or more video objects (VOB - Video Object Block ). The basic element of the DVD is the video object (VOB). It contains video, audio and multiplexed images, stored in the in MPEG2 format. Thus, a .VOB file can be read by most video player software, by changing its extension to .MPG.
- A copy of the VTSI ( VTSI Backup).
A DVD can hold up to 99 titles (VTS), each divided to 10 chapters.
The VIDEO_TS folder usually contains three types of files, with the following extensions:
- IFO containing navigation information.
- VOB (Video Object Block) containing the video stream, the audio channels and subtitles of a video title .
- BUP (BUP - Backup file) containing a backup of IFO files.
The file named as VIDEO_TS.IFO (
IFO - information) contains the necessary information for the DVD player to display the main menu. It is accompanied by VIDEO_TS.VOB
file containing the introduction animation, as well as a backup file (named as VIDEO_TS.BUP).
