OGV (Ogg Video (Theora)) is best for distributing open-source and royalty-free video content without patent concerns. MP4 (MPEG-4 Part 14) is best for streaming and sharing video online with the widest possible device and platform compatibility. Key tradeoff: OGV's advantage is completely patent-free and open-source (theora codec + ogg container), ideal for freedom-respecting projects, while MP4's advantage is universal playback support — every browser, phone, smart tv, and streaming platform handles mp4 natively.
Pro Tips for OGV to MP4 Conversion
