What is a VOB File?

Last Update date : Oct 12. 2020

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. It contains the actual Video, Audio, Subtitle, and Menu contents in stream form.

 

If the VOB filename extension is changed from .vob to an MPEG-2 type file extension such as .mpg or .mpeg, the file is still readable and continues to hold all information, although most MPEG-2-capable players don't support subtitle tracks.

 

In order to burn the VOB files to a DVD±R disc, other standard DVD-Video files are needed as well, including IFO and BUP files. The burning is easily done using software like K3b, Nero, Roxio Toast or ImgBurn.
