F4V is Adobe's Flash video container using H.264/AAC in an ISO BMFF structure. OGV (Ogg Video) is the Xiph.org open-source video container that pairs Theora video with Vorbis audio. Theora is a royalty-free video codec derived from VP3, offering reasonable quality at moderate bitrates. Converting F4V to OGV creates a completely patent-free video file suitable for open-source platforms and free software projects.
OGV is the video format of choice for projects that require patent-free, royalty-free codecs — including Wikipedia (which uses OGV for all video content), open-source software documentation, and Creative Commons media. Firefox historically supported OGV natively when it refused to implement H.264 for licensing reasons. If you need video that can be freely redistributed without any codec licensing concerns, OGV is the answer.
FFmpeg decodes the H.264 video from the F4V container and re-encodes it using the libtheora encoder. Theora uses block-based DCT compression similar to H.263 but without patented techniques. Audio is re-encoded using libvorbis. The OGV container uses Ogg page framing with theoraenc and vorbisenc as the muxed streams. Quality can be set via a target bitrate or Theora's quality parameter (0-10, default 7). The encoder supports up to 1080p but is most efficient at 480p-720p.
Theora is less efficient than H.264 — at the same bitrate, H.264 produces visibly better quality. To match the visual quality of a 2 Mbps H.264 source, Theora typically needs 3-4 Mbps. At 720p with 4 Mbps, Theora produces acceptable quality for web delivery. For archival quality, increase the bitrate significantly. The format shows its age with fast motion and detailed textures.

F4V to OGV conversion is specifically for projects that require 100% patent-free video. Quality is lower than modern codecs, but the complete freedom from licensing concerns is valuable for Wikipedia contributions, open-source projects, and freely redistributable media.
