DVD VOBs store MPEG-2 video with AC3/DTS audio — both patented formats. OGV (Ogg Video) uses Theora video and Vorbis audio — both completely royalty-free. Converting VOB to OGV produces open-format video suitable for platforms requiring patent-free media, notably Wikimedia Commons.
Platforms like Wikimedia Commons, open educational resource repositories, and open-source project sites require royalty-free video formats. OGV provides this, making DVD content eligible for upload to these platforms. The conversion removes all proprietary codec dependencies.
However, Theora is significantly less efficient than MPEG-2, so file sizes may increase at comparable quality. For better open-source compression, consider WebM instead.
FFmpeg deinterlaces the VOB's MPEG-2 and transcodes to Theora using libtheora with Vorbis audio using libvorbis in the OGG container. Theora quality is controlled by -q:v (0-10 scale). DVD resolution is maintained or downscaled. The deinterlacing removes combing artifacts for Theora's progressive encoding.
Theora is roughly comparable to MPEG-2 in compression efficiency, so file sizes at similar quality are comparable. At quality 7, Theora at DVD resolution produces acceptable results. For better quality-per-bitrate in open formats, WebM with VP9 is significantly superior.
