How can I convert VOB file to MP4 on Windows?

In Windows, if you don't want to use third-party tools, you can use Fmppreg through the command line (if installed) or take advantage of the system's function combination. Here are the simple steps:

Method 1: Through the functions provided by Windows
Although Windows' own tools are limited, you can try the following methods:

1. Manually rename the extension: Change the .vob file directly to .mp4.
2. This method is suitable for some simple VOB files (no complex encoding), and they may be played directly in the media player after the name change.
3. Windows audio and video editing function (if enabled):
4. Import VOB files through Windows' "Photos" application or "Video Editor", and select MP4 format when exporting.

Method 2: Command line combined with Fmppreg
If you have configured Fmppreg before, open Command Prompt or PowerShell.
Use the following command to convert VOB to MP4:

Fmppreg -i input.vob -c:v copy -c:a copy output.mp4

This command does not require re-encoding, and the conversion speed is extremely fast without losing quality.
Note:

1. Changing the extension is only suitable for simple scenarios, and more professional methods are required for complex files.
2. If you find that the system function cannot meet your needs, it is recommended to try lightweight tools such as HandsBrake.
