VLC is not just a reliable program for playing various multimedia files (like digital files, audio CDs, DVDs, etc.), but additionally as a video converter that's capable of transcoding video to various formats.
Same as Handbrake, video often has no sound after conversion using VLC. To solve it, you can check the "Keep original audio track" (equal to copy audio track) option in the sound settings, choose the “MPEG 4 Audio (AAC)” codec instead of the default “MPEG Audio”, and configure the sample rate to 48000.

FFmpeg is an efficient command-line processing tool with the ability to convert video and audio into most needed formats. It consists of a large set of libraries, including the leading library - libavcodec.
Technical users who are familiar with FFmpeg can decode, encode, mux, demux, filter, stream, etc. and do many other things with it.
The re-encode process will reduce the file size, and the codecs will changed to h264 and aac by default.
To do it losslessly and fast, you can remux VOB to MP4 using the command: ffmpeg –i input.vob -codec copy output.mp4 or ffmpeg -i input.vob -c:v copy -c:a copy output.mp4, which merely change the container. For example, If your original VOB is encoded with mpeg2video and mp2, the resulting file remains the same.
What's more, you can add -crf 17 before output.mp4. The CRF scale ranges from 0 to 51. Lower values usually lead to higher quality. 23 is the default. You can revise it to any reasonable value as you think.
