OGV (Ogg Video) pairs Theora video with Vorbis audio in Xiph.Org's open container — producing completely patent-free video files. While both RMVB and OGV are niche formats in 2024, OGV serves specific open-source use cases where patent freedom is legally mandated. Theora's compression efficiency is lower than both RealVideo and H.264, so this conversion trades compression efficiency for licensing freedom.
OGV is required by Wikimedia Commons, certain government open-standard mandates, and open-source projects with strict patent-free policies. When RMVB content needs to be published on these platforms, OGV conversion is necessary regardless of the efficiency tradeoff.
FFmpeg decodes RealVideo and RealAudio, then encodes to Theora using libtheora and Vorbis using libvorbis. Theora encoding uses a quality target (0-10) where 6 is typical for web video. Resolution should be multiples of 16 for optimal Theora encoding. Two-pass encoding is recommended for best quality.
Theora is less efficient than both RealVideo and H.264 — expect OGV files 30-50% larger than the RMVB source at equivalent quality, or visibly lower quality at the same file size. The conversion involves quality sacrifice for licensing freedom.

RMVB to OGV conversion serves specific open-source and open-access requirements where patent-free video is mandatory. For any other use case, MP4 or WebM provide dramatically better quality and compression.
