What changes when you convert VOB to MP3
This extracts the audio and discards the video entirely. The soundtrack inside a VOB file is typically AC-3, and it is re-encoded to MP3 on the way out.
Expect a much smaller file. Video accounts for most of the bytes, so about 49 MB per minute becomes roughly 1.7 MB per minute of MP3.
Subtitles do not survive audio extraction, since an audio container has nowhere to store them.
When a video holds several audio tracks, the main one is extracted; alternate language tracks are not merged into the result.
About VOB to MP3 Conversion
Extracting MP3 audio from a VOB video pulls the soundtrack out of the DVD-Video (MPEG-2 PS) container and writes it as a standalone MPEG-1/2 Audio Layer III file. The video stream, which holds most of the data, is discarded.
Developed by DVD Forum in 1996, VOB stores audio using MPEG-2. That codec choice sets the upper bound on what any conversion can preserve.
MP3, from Fraunhofer IIS / MPEG and dating to 1993, uses MP3 and plays natively on 6 of the six platform categories we track. That combination is usually why people convert into it.
After converting your file, you can use Scriptivox transcription services to convert your audio to text. Perfect for meetings, interviews, podcasts, and more.
