Convert VOB to IFO

Understanding VOB and IFO file formats

VOB (Video Object) files are core components of DVD-Video discs, containing the actual video, audio, subtitles, and menu contents in a multiplexed format. These files are typically found in the VIDEO_TS folder of a DVD and have the extension .vob.

IFO (Information) files, also located in the VIDEO_TS folder, do not contain video or audio data. Instead, they store important navigation and playback information, such as chapter markers, menu structure, and the mapping of VOB files. The extension for these files is .ifo.

Can you convert VOB to IFO?

Directly converting a VOB file to an IFO file is not possible in the traditional sense, as they serve different purposes. However, if you have VOB files and need to generate corresponding IFO files (for example, to rebuild a DVD structure for playback on DVD players), you can use DVD authoring software to create the necessary IFO files from your VOB content.

Best software for creating IFO files from VOB

The most reliable way to generate IFO files from VOB files is to use DVD authoring tools. Here are some recommended options:

• DVDStyler (Windows, macOS, Linux): Free and user-friendly, it allows you to import VOB files and author a DVD structure, automatically generating IFO files.
• IFOEdit (Windows): A specialized tool for creating and editing IFO files. You can use it to author new IFO files from existing VOBs.
• Nero Burning ROM (Windows): A commercial suite that includes DVD authoring features, allowing you to import VOB files and export a DVD structure with IFO files.

How to create IFO files from VOB using DVDStyler

1. Install and launch DVDStyler.
2. Click File → New to start a new DVD project.
3. Drag your VOB files into the project timeline.
4. Customize menus and chapters as needed.
5. Click File → Burn DVD or File → Create ISO Image to generate the DVD structure.
6. The output folder will contain the VIDEO_TS directory with both VOB and newly created IFO files.

Summary

While you cannot directly convert a VOB file to an IFO file, you can use DVD authoring software like DVDStyler or IFOEdit to generate the necessary IFO files from your VOB content, enabling proper DVD playback and navigation.
