OGVからiPhone Videoへの変換について
OGV files use Theora video with Vorbis audio in the Ogg container — all open-source codecs that the iPhone cannot decode. iPhones require H.264 or H.265 video with AAC audio. The iPhone Video preset produces optimized MP4 content tailored for the iPhone's hardware decoder, display resolution, and power efficiency requirements.
OGVをiPhone Videoに変換する理由
iPhones have no native support for Theora or Vorbis codecs. OGV files cannot play in the Photos app, Safari, or any native iOS media framework. Even VLC on iOS software-decodes Theora with significant battery drain. Converting to the iPhone preset enables hardware-accelerated playback with optimal battery life.
This conversion is especially important for sharing open-source video content with iPhone users who make up nearly 50% of the smartphone market in many countries.
主な活用例
- Making OGV educational videos from Wikimedia viewable on students' iPhones
- Converting open-source conference recordings for iPhone distribution to attendees
- Preparing OGV tutorial content for iPhone viewing in educational and training contexts
- Sharing open-format video via iMessage, which requires H.264/H.265 in MP4/MOV
- Loading OGV documentary content onto iPhones for offline mobile viewing
仕組み
FFmpeg decodes the OGV's Theora video and Vorbis audio, then transcodes to H.264 High Profile Level 4.1 or H.265 Main Profile with AAC-LC audio. Resolution targets up to 1920x1080 for optimal iPhone display quality. Bitrate is set to 5-8 Mbps for 1080p. The output MP4 uses faststart for instant playback and includes proper Apple metadata for orientation handling.
品質とパフォーマンス
The iPhone-optimized output is significantly better than the OGV source at comparable file sizes. H.264's superior compression means the converted video looks sharper and more detailed than Theora at the same bitrate. On the iPhone's small, high-DPI display, quality is excellent.

最良の結果を得るためのヒント
- 1Use H.265 for newer iPhones (7+) to get smaller files with equivalent visual quality
- 2Target 1080p for the best viewing experience on modern iPhones — 720p saves storage for older models
- 3Set CRF 24 for compact files that look great on iPhone Retina displays
- 4Use AAC at 128 kbps stereo — this is optimal for iPhone audio playback
- 5Enable faststart for instant playback when sharing via web links or cloud storage
