Online VOB mergers are generally full of ads, and are bound to slow upload speed, especially when your network environment is not that ideal. Besides, the file size is generally limited, ranging from 100mb to 500mb, which is small especially when the VOB file can be up to 1GB.

3. Can Handbrake combine .vob files?

If you’ve ever googled “how to combine VOB files?”, you may be informed to use Handbrake to combine VOB files or other videos from some unauthorized pages. If you follow these untruthful instructions, I can assure you that you may get distressed with Handbrake merging. In our test, it just enabled to convert multiple .vob files in batch and created separated MP4 or MKV files for each of the VOB files.

This has also been proven by Handbrake itself. According to Handbrake documentation, combining multiple video clips into one is one of the features Handbrake doesn’t support so far. You will need other video merging tools in order to stitch multiple VOB files into one. In addition, if the VOB files are extracted from commercial DVD discs, they can be copy-protected, which Handbrake cannot cope with. Click here to see whether Handbrake can merge videos >>

4. How to combine multiple .vob files to a single .mp4 file using VLC?

VLC is one of the few open-source media players to become a worldwide household. It enables you to open and play any media files without downloading any third-party codecs.

It is true that you may have found several results on Google regarding how to combine multiple VOB files into one using VLC media player. They just told you to load multiple VOB files by clicking Open Multiple Files from the Media drop-down list, add the VOB files you want to merge, and then click Convert from the Play drop-down menu. However, VLC isn’t functional when it comes to merging video files by following these sources. In our tests, VLC just transcoded VOB files in batch and left you with separated output videos.

If you want to combine multiple VOB files into one single content, you can follow the trustful VLC documentation, enter the command lines to merge and transcode multiple videos here.

> "(path)vlc.exe" file1.vob file2.vob file3.vob --sout "#gather:std{access=file,mux=mp4,dst=merged.mp4}" --no-sout-all --sout-keep

Command line explanation: please replace the (path)with the truly location of your VLC media player on your computer. The file1, file2, file3 refer to the respective names of your source VOB files. The merged.mp4 refers to the name of the final merged video.

Note: The source VOB files to be combined must have horizontal orientations. If the vob files are of vertical orientations, VLC may run into troubles while merging .vob files.

VLC doesn’t combine or transcode any copy-protected VOB files. If the VOB files are saved from commercial DVDs,they are likely to be encrypted with CSS, region code, Disney X-project DRM, etc, VLC command line won’t work. For example, the merged VOB file has no image, there is audio sync error, and so on. So make sure the VOB files are unprotected.

If it is relatively complicated and merging files is faulty using VLC command line, you can try Winxvideo AI for help.

5. How do I combine vob files on a Mac?

iMovie is a famous video editing software for Mac users, with which you can edit and merge video files on Mac computer. However, if you have VOB files and would like to merge them into one on your Mac, iMovie may fail to work. For the first thing, iMovie won’t import any VOB file stored in commercial DVD disc. It is likely to be encoded with copy protection scheme that iMovie cannot crack. For the other thing, even if the VOB file is unprotected, it is generally encoded with MPEG-2 codec, which is of GOP content that is not edit compatible with iMovie at the frame level.

In this regard, iMovie isn’t the optimal tool to combine VOB files on Mac. But you can rely on the powerful MacX Video Converter Pro, a Mac-based video converter and editor that is able to make the task of VOB merging hassle-free. All you have to do is to load the VOB files into the interface, choose MP4 as the output format or leave the format unchanged, click merge box, and tap RUN button to start the merging process.

6. How to merge DVD VOB files?

If you’ve got VOB videos at the root of a commercial DVD, chances are these VOB files are copy protected. This makes merging VOB files a tricky task, especially when the video merging tool cannot cope with copy protection measures. So when it comes to merging DVD VOB files, you’d better find a tool that can not only fulfill your DVD VOB combining needs, but also get rid of copy protection so that the final video can be played flawlessly. WinX DVD Ripper Platinum is one such tool that can fit your bill.

Received high accolades from tech giants like TechRadar, PCWorld, the DVD ripper can rip any protected DVD folder, VOB, ISO image and merge multiple titles together. To do the task, you can load the DVD Video_TS folder, where the VOB files are located. The program will automatically read the title, regardless of the copy protection measures. Then you can check the title boxes that you want to merge, choose an output format, check the Merge titles box in the top side of the main interface, and then press RUN to begin merging DVD VOB titles.
