What a VOB file is and why you might have one

A VOB file is a video file format used on DVDs. The letters stand for "Video Object", and these files contain the actual movie, TV show, or other video content that plays when you put a DVD in a player. If you've copied files from a DVD to your computer or downloaded video content, you may end up with VOB files instead of the more common MP4 or AVI formats.

VOB files are not difficult to play — most modern media players can handle them — but they're not as straightforward as clicking a file and having it open automatically. This guide walks you through the actual steps to get a VOB file playing on your computer right now.

Key Takeaways

  • VOB files play in most modern media players, but Windows Media Player and some Mac players may not recognize them without extra software.
  • VLC Media Player is free, works on Windows, Mac, and Linux, and plays VOB files without any setup or conversion needed.
  • If you have multiple VOB files from the same DVD, they are usually meant to be played in order as a single video.
  • Converting a VOB file to MP4 or another format takes a few minutes with free software and makes the file easier to share and play on other devices.

Playing a VOB file with VLC Media Player

The fastest way to play a VOB file is to use VLC Media Player, which is free and works on Windows, Mac, and Linux. VLC plays VOB files without requiring any conversion or extra steps. If you don't have VLC installed, download it from videolan.org — the site is safe and the download is straightforward.

Once VLC is installed, right-click the VOB file on your computer. Select "Open with" and choose VLC Media Player from the list. The file will open and begin playing immediately. If VLC doesn't appear in the "Open with" menu, click "Choose another app" and scroll down to find VLC in the full list of installed programs.

If you prefer not to right-click each time, you can set VLC as the default player for VOB files. Right-click a VOB file, select "Open with", then click "Choose another app". Find VLC, check the box that says "Always use this app to open .vob files", and click "Open". From then on, double-clicking any VOB file will open it in VLC automatically.

Playing VOB files on Mac

Mac's built-in QuickTime player does not play VOB files. The easiest solution is to download VLC for Mac from videolan.org — it's free and works the same way as the Windows version. Once installed, right-click the VOB file, select "Open With", and choose VLC.

If you want to use a different player, Infuse is another option that plays VOB files on Mac. Infuse is not free, but it offers a trial period. For most people, VLC is the better choice because it costs nothing and requires no setup.

What to do if you have multiple VOB files

DVDs often split their content across several VOB files. If you have multiple files named something like "VTS_01_1.vob", "VTS_01_2.vob", and "VTS_01_3.vob", they are meant to play in order as one continuous video. Playing them one at a time will break up the movie or show.

In VLC, you can play them in sequence without manually starting each file. Open the first VOB file in VLC. When it finishes, VLC will automatically move to the next file in the same folder if the files are numbered in order. If this doesn't happen, open VLC's playlist (press Ctrl+L on Windows or Command+L on Mac), drag all the VOB files into the playlist in the correct order, and play them from there.

Converting a VOB file to a more common format

If you want to convert your VOB file to MP4, AVI, or another format so it plays on more devices, you can use free software like HandBrake. Download HandBrake from handbrake.fr, install it, and open the program. Click "Open Source" and select your VOB file. Choose your desired output format from the "Format" dropdown — MP4 is the most widely compatible option. Click "Start" and the conversion will begin. Depending on the file size, this may take anywhere from a few minutes to an hour.

Conversion is useful if you plan to watch the video on a phone, tablet, or older media player that doesn't recognize VOB files. It also makes the file smaller and easier to share. The trade-off is that conversion takes time and uses your computer's processing power while it runs.

Troubleshooting when a VOB file won't play

If you've opened a VOB file in VLC and it won't play, the file may be corrupted or incomplete. Try opening a different VOB file from the same source to see if the problem is with that specific file or with all of them. If other files play fine, the first file is likely damaged and cannot be repaired.

If no VOB files will play, restart your computer and try again. Sometimes a temporary software conflict prevents playback. If the problem persists after a restart, uninstall VLC completely, download it again from videolan.org, and reinstall it. This usually fixes any playback issues caused by an incomplete installation.

If you see an error message about a missing codec, this is rare with VLC because VLC includes all the codecs it needs built in. If you see this message, it likely means you're using a different media player. Switch to VLC instead, which will play the file without any codec errors.

Playing VOB files on a TV or media device

Most modern smart TVs and media streaming devices do not play VOB files natively. If you want to watch a VOB file on your TV, convert it to MP4 using HandBrake as described above, then transfer the MP4 file to a USB drive. Plug the USB drive into your TV or media device and play the file from there. Most TVs recognize MP4 files without any additional software.

Alternatively, if your computer is connected to your TV via HDMI cable, you can play the VOB file on your computer and display it on the TV screen. Open the VOB file in VLC on your computer, connect the HDMI cable, and the video will appear on your TV while you control playback from your computer.

Frequently Asked Questions

Can I play a VOB file on my phone or tablet?

Most phones and tablets do not recognize VOB files. Convert the file to MP4 using HandBrake on your computer, then transfer the MP4 file to your phone or tablet. From there, you can play it using your device's built-in video player or any video app you have installed.

Why are there so many VOB files instead of one video file?

DVDs split video content across multiple files for technical reasons related to how DVD players read data. These files are meant to play in sequence. When you play the first file in VLC, it will automatically continue to the next file if they're in the same folder.

Is it legal to convert a VOB file from a DVD I own?

This depends on your country's copyright laws and whether the DVD has copy protection. In many places, converting a DVD you own for personal use is permitted, but the specifics vary. Check your local laws before converting copyrighted content.

What if VLC plays the VOB file but there's no sound?

Right-click the video while it's playing in VLC and select "Audio Track". If multiple audio tracks are listed, try selecting a different one. If only one track appears, the file may have a corrupted audio stream. Try playing a different VOB file to see if the problem is specific to that file.

Can I edit a VOB file?

VOB files are not designed for editing. Convert the file to MP4 or another format using HandBrake, then use video editing software like DaVinci Resolve (free) or Adobe Premiere to make your edits. Save the edited version as a new file.
