O převodu VOB na OGV

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.

Proč převádět VOB na OGV?

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.

Jak to funguje

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.

Kvalita a výkon

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.

Tipy pro nejlepší výsledky

1Use Theora quality 7-8 for acceptable visual quality from DVD sources
2Always deinterlace before Theora encoding — Theora is a progressive-only codec
3Consider WebM instead if the target platform accepts it — VP9 is dramatically more efficient
4Keep DVD resolution — downscaling adds an extra quality loss step
5Add proper OGG metadata for Wikimedia Commons and repository requirements

VOB to OGV converts DVD content into a fully royalty-free format for open platforms, though WebM is recommended for better compression when accepted.

Často kladené otázky

Some platforms (Wikimedia) historically required OGV. WebM is more efficient. Both are open formats — check the target platform's requirements.

Theora is a progressive codec. The conversion must deinterlace the DVD content before Theora encoding.

At comparable quality, OGV is roughly similar in size to VOB — Theora and MPEG-2 have similar compression efficiency.

Firefox and Chrome support OGV natively. Safari does not. Provide an MP4 fallback for universal browser support.

WebM for better compression (VP9 is far more efficient than Theora). OGV only when specifically required by the target platform.
