Part 1. What is a VOB File and Why Convert VOB to MP4 for Universal Playback?
Before diving into how to convert a VOB file into MP4, let's find out what a VOB file actually is. It's a type of file found inside a DVD's VIDEO_TS folder that holds your main video, sound, menus, and subtitles. It works fine on DVD players, but newer devices usually can't open it.

Using MP4 can help solve these issues. MP4 works on almost every device, compresses video without huge quality loss, and moves faster when you upload or send it. Converting VOB to MP4 keeps the video easier to store, edit, and play across different platforms.

Part 3. Troubleshooting: Common VOB to MP4 Conversion Issues and Fixes
Even after learning how to convert VOB files to MP4, you may still run into a few problems along the way. Issues like files won't import, lose audio after conversion, or the video refuses to open are common with DVD-based formats. But you can fix them once you know what causes them.

Here are a few of the common VOB to MP4 conversion issues with their fixes.
1. Encrypted VOB Files Won't Convert
Some VOB files come from DVDs with copy protection. When you load them into VLC, HandBrake, or Filmora, the tools may refuse to open the file or stop during conversion.
- Fix: Use a DVD decrypter to remove the protection before you convert the file. After that, reload the VOB file into your converter and try again.
2. VOB File Won't Import Into Your Converter
Sometimes, the converter doesn't recognize the VOB file even though it's valid. This situation often happens when the file name or path is too long.
- Fix: Rename the file using simple letters and move it to a different folder on your desktop.
3. Converted MP4 Has No Audio
If your converted MP4 has no sound, the issue usually lies in the audio codec. Some VOB files use formats that certain converters skip during processing.
- Fix: Reconvert the file and select AAC or MP3 as the audio codec. HandBrake and Filmora both let you set the audio track manually before exporting.
4. The VOB File Is Too Large
VOB files can easily reach several gigabytes, making them hard to upload or convert on low-end systems.
- Fix: Split the file into smaller parts or lower the output bitrate before converting. In Filmora or HandBrake, you can set a custom bitrate to reduce size without losing much visual quality.

FAQs
-
Why are VOB files split into multiple, numbered parts (VOB, VOB1, etc.) within the VIDEO_TS folder?
DVDs break videos into several VOB parts to manage size limits and menu structure. Each part stores a section of the movie, and the DVD player stitches them together during playback. -
I converted VOB to MP4, but the audio is missing. Why does VOB audio often disappear?
The audio track may use a codec your converter didn't select or support. Choose the correct audio track and set AAC or MP3 as the codec before converting again. -
Can my converted MP4 file be larger than the original VOB file, and why?
Yes. MP4 can grow bigger if you use higher bitrate, resolution, or encoder settings than the original file. Lower the bitrate or pick a lighter preset to reduce the size. -
Is it legal to convert a protected DVD's VOB files to MP4 format for personal use?
It depends on local law. Some places allow personal backups, while others restrict copying protected discs. Check the rules in your region to stay safe.
