How to convert .vob to .m4a with VOB to M4A Converter?

The step-by-step tutorial shows you how to convert .vob to .m4a format files with VOB to M4A Concverter.

What is vob?

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 some additions. It contains the actual Video, Audio, Subtitle, and Menu contents in stream form. If the VOB file 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.

What is m4a?

M4A, Audio file that uses MPEG-4 audio compression; uses the same compression as an .MP4 video file, but does not contain a video track. MPEG-4 audio files that include copyright protection, such as those sold from the iTunes Music Store, usually have with the .M4P extension.

The existence of two different file extensions for naming audio-only MP4 files has been a source of confusion among users and multimedia playback software. Since MPEG-4 Part 14 is a container format, MPEG-4 files may contain any number of audio, video, and even subtitle streams, making it impossible to determine the type of streams in an MPEG-4 file based on its filename extension alone. In response, Apple Inc. started using and popularizing the .m4a file extension. Software capable of audio/video playback should recognize files with either .m4a or .mp4 file extensions, as would be expected, as there are no file format differences between the two. Most software capable of creating MPEG-4 audio will allow the user to choose the filename extension of the created MPEG-4 files.
