VOB File - What Is a VOB File and How do I Open It?

VOB is a popular video file format for DVD files. But despite its excellent picture quality, the VOB file isn't natively supported on some mobile and desktop players. And even if you install a VOB player, most can't open this file format with the original quality. For these few reasons, I want to introduce you to the best VOB players for Mac and Windows PCs. Also, we'll learn how to losslessly convert VOB to MP4 for smooth playback on mobile or PC.

Part 1. What is a VOB file?

VOB (Video Object) is a video container used in DVD media. It uses a .vob filename extension and can contain digital video, audio, subtitles, and DVD menus. That said, VOB is usually encoded in MPEG-2 Part II/H.262 or MPEG-1 Part I. As for audio, VOB uses DTS or AC3 formats. Unfortunately, AAC isn't supported in VOB.

Having said that, content for a single title in a VOB file is divided into 1GB bits. That's because some operating systems don't open files larger than 1GB. Also, VOB files often come with IFO or BUP files, containing relevant information about the DVD media. And, of course, some DVD files are encrypted using CSS (Content Scramble System).
