How to Convert (Encrypted or not) DVD VOB Files to AVI on PC/Mac

Follow this guide on how to convert VOB, located in or copied from commercial & homemade DVD, to AVI with high quality on Windows (10), macOS Mojave etc.

We often come across VOB video file when converting general video formats into NTSC/PAL for DVD burning, copying DVD disc into VIDEO_TS, or opening DVD movie after inserting it successfully into the DVD drive. So what is VOB? What's the relationship between VOB and DVD? And if you want to convert (DVD) VOB files to AVI without losing video quality on Windows or macOS based computer for playback or editing, what should you do? Well, this


VOB, encoded with MPEG-2, is a container format in DVD-Video. As one of the Video Manager and Video Title files under VIDEO_TS directory, VOB stores all the media content of a DVD, including digital video, digital audio, subtitles, DVD menus and navigation of a DVD. Another two information files are IFO and BUP respectively, the former of which contains video control and playback information while the latter is just the backup copy of IFO. Let's make it much clearer by checking a DVD-Video structure picture:

Every DVD disc has a suite of Video Manager (VMG) files to manage the entire DVD and multiple Video Title Set (VTS) files to control the real content. Since each .vob file has a maximum storage size of 1GB, the amount of VTS files varies from DVD discs.

It's easy to play DVD (MPEG2) VOBs on DVD player and many famed media players like VLC. However, VOB is still rejected by many mainstream smart devices and gaming consoles. To have VOB accepted by more machines and still editable, converting VOB to AVI is a wise way to go.
