VOB files are essentially MPEG-2 files - you can change the file extension from VOB to MPG and it should play back fine. I'm in agreement with Warren to pull out the audio separately and then match it back in PPro - it's obvious PPro has issues dealing with the highly compressed audio segment of the video. Kristian is also right to re-encode the VOB to a more compliant format for editing. If you are going to H264, try setting a bitrate of 10-25 Mbps - test out a short section before proceeding, ...

Yikes!  That's unexpected for sure.

While this adds an extra step, have you tried exporting the audio from VLC Player and then dropping that under the picture in Premiere Pro?  You could also opt to export the picture and sound form VLC Player.

You could also try Handbrake, Mac Video Ripper Pro or DVDxDV Pro (that last one is for professional convention of DVD-Video to video editing formats, but it hasn't been updated and may require an older version of macOS to run).

You could also double-check that your Premiere Pro is up-to-date.  Sometimes that resolves issue like this.  Sometimes it does not.

Wow! That is definitely a difference and unfortunately very common. While VOB files can play fine from a desktop level, it is better to decompress them into an intermediate codec for smoother decode in Premiere. Even converting VOB to H.264 can greatly improve the playback. I'm with Warren on the fact that Handbrake is a great choice if you continue to have issues with with the conversion. So as a summary:

Review: VOB is not a great editing format and should function better in an intermediate codec.

One Possible Solution: Use Media Encoder to encode to a Quicktime/Prores, Quicktime/Cineform or at least an H.264.

Backup Possible Solution: Use Handbrake or 3rd Party to encode to another, more stable codec for editing.

The reason I would probably use Prores or Cineform is that the audio can be decompressed to an uncompressed format like a WAV or AIF conversion--they can often fix tricky audio. There are other options for fixing but this is what I would try first. Good luck!

I have just changed the file extension on an old .VOB file to .MPEG and the audio now works perfectly. I had been trying to import into Premiere Pro and the audio was not playing at all. Thank you!

Do what we did in the old days: convert to plain old sd-mov or dv avi for windows.

You can do this with CS6 which is more forgiving with old footage.

It's really a long time ago that I had to do such hacks. VOB files are relatively complex multiplexed video and (multiple) sound files. There exist tools to demultiplex VOB files without converting.

You may find more info here:

Abambo makes a good point regarding the structure of vobs.

What is multiplexed in the vob file can be many streams, video, audio, subtitles, etc. And there can be more than one audio stream. And sometimes, you get vobs from disks done using very unstandard specs.

I would use MediaInfo to look at what the audio stream(s) have in them.

Extracting the audio stream without converting can save quality loss. But here the more important problem may be whether the audio stream you are extracting is the wrong one, or whether it is in an odd format.

I've been searching for awhile to find a good way to convert a .VOB file format to a .MP4, .MOV, or other without losing sound! I finally tried Apple MacBook Compressor and that worked like a charm.
