About OGV files

Strengths Comparison

MP4 Strengths

  • Universal playback — every browser, phone, TV, game console, and editing suite reads MP4.
  • Supports modern codecs (H.264, H.265, AV1) with no container changes.
  • Progressive streaming works with the "moov atom" at the start of the file.
  • Carries subtitles, chapters, multiple audio tracks, and embedded metadata.
  • ISO-standardized (ISO/IEC 14496-14) and patent-licensable via MPEG LA.

OGV Strengths

  • Patent-free codec (Theora) and container (Ogg).
  • Mandatory for Wikipedia uploads — preserves public-domain video.
  • Good for small educational clips.
  • Open-source reference implementations.

Limitations

MP4 Limitations

  • Codec licensing (H.264, H.265) carries royalty costs for commercial use.
  • Streaming requires the moov atom at the start — a misplaced atom breaks web playback.
  • Not ideal for lossless or professional editing workflows (use ProRes or DNxHD instead).
  • Editing an MP4 almost always re-encodes, degrading quality.

OGV Limitations

  • Compression lags H.264 by ~40% at equal quality.
  • Hardware decoders never adopted Theora.
  • WebM (VP9/AV1) is the modern open-codec choice.
  • iOS and Safari never supported Theora natively.
