In fact, VLC is able to convert videos from one format to the other. It supports VOB video, Video_TS VOB, DVD, network files, and recordings.

Part 2. Common Problems During VOB to MP4 Conversion on Mac

Converting VOB to MP4 on Mac is anything but smooth. There are complaints about the sound, subtitles, codecs, etc. converting using HandBrake or others. While free VOB to MP4 converting on Mac can be loaded with problems, sad users can take solace in the fact that the VOB to MP4 converters above have fixed some common problems you may have experienced:

* VOB to MP4 sound problems

"When I try to free convert a vob to mp4 with Handbrake on Mac, the sound of some files are horrible (distorted) after the conversion, but the vob plays with no problem." Most users who ran into sound problem will have audio distortion or bad sound quality, while some even worse, get no sound after the conversion.

* Vob conversion error with subtitles

Another common problem with Mac freeware involves video subtitles. For example, "I've converted the VOB files to MP4's, but the subtitles are gone! All I really need is a program that will keep the subs ON, after conversion from a VOB.", or "the subs are improperly synced with the audio in the exported MP4, while the vob file ripped from DVD was OK."

* Vob to mp4 conversion on mac finishes parts only

Sometimes the free tool won't convert the full VOB files without giving any reason. After an hour or so, the ended file gives about 1/3 the size and it only gets the first part finished in MP4 format.

* Corrupted vob file

Many users may have some corrupted vob files but can't get a solution to process them. "I need the last part of a vob file but there is corruption approx half through the video. The error prevents me to free transcoding VOB files to mp4 on mac." To be specific, this is not a converting problem.

* Incorrect aspect ratio

The output MP4 videos are different from the original vob files on the display screens. As a user complain that "the new mp4 file was about 50% of the original width and therefore the videos are distorted." For those who want the picture to fill the entire screen of the TV or computer, the distorted or out-of-shape image looks really disappointing.

* Audio/Video out of sync

"I am attempting to convert the VOB files to MP4 for more compatible use on Mac but have issues with the audio once the conversion is complete. The audio first starts out correct but later on it starts to go out-of-sync." Some users are experiencing A/V out of sync errors after they convert VOB to MP4 on Mac, while some others get no audio after the conversion.

To get rid of any of the above errors, get MacX Video Converter Pro and freely convert VOB to MP4 videos on Mac (macOS 13 Ventura incl.)

Extended Knowledge:

VOB: VOB is a container format in DVD-Video media that contains audio, video, subtitles, DVD menus, and other contents. VOB can be played by a DVD player, and a few video players like Windows Media Player and VLC Media Player. However, vob is not supported by all mobile devices, editors like Windows Movie Maker, Final Cut Pro, iMovie, etc., and video sharing sites. The good part is that VOB keeps very low compression.

MP4: MP4 is a digital multimedia container format most commonly used to store video, audio, and subtitles. MP4 is the widest-supported format which is compatible with almost all mobiles, players, websites, editors etc. Besides, mp4 is a format that well balances the quality and file size. If you change a VOB to MP4 for small screens, you can hardly notice any quality differences.
