O převodu MXF na OGV

MXF (Material Exchange Format) is the SMPTE ST 377 professional container for broadcast and post-production, carrying codecs like DNxHD, ProRes, AVC-Intra, and XDCAM with extensive metadata. OGV (Ogg Video) is the Xiph.org Foundation's open-source video container using Theora video and Vorbis audio codecs — both completely patent-free and royalty-free. OGV was historically important as the only open video format supported by Firefox and Wikipedia.

Converting MXF to OGV moves professional broadcast content into a fully open-source video format. While OGV has been largely superseded by WebM (VP9/AV1) for new web deployments, it remains relevant for Wikimedia Commons uploads, open-source institutional media systems, and projects with strict royalty-free format requirements.

Proč převádět MXF na OGV?

Wikimedia Commons — the media repository for Wikipedia — has historically used OGV as its primary video format due to its completely patent-free status. Broadcast documentaries, educational content, and public-domain footage stored in MXF format often needs conversion to OGV for Wikipedia integration and open educational resources.

Government agencies, public institutions, and educational organizations with open-format mandates may require OGV for all publicly distributed video content. The Theora+Vorbis codec combination has no patent encumbrances, no licensing fees, and no usage restrictions. For archival and institutional distribution of broadcast content under open-access policies, OGV provides complete legal clarity.

Jak to funguje

FFmpeg demuxes the MXF container, decodes the professional codec, and re-encodes to Theora video with Vorbis audio in the OGG container. The pipeline: `-c:v libtheora -q:v 7 -c:a libvorbis -q:a 6`. Theora quality scale ranges from 0-10, where 7 produces good quality at moderate bitrates. Broadcast MXF content should be deinterlaced before encoding since Theora handles progressive content much better than interlaced. Resolution should typically be scaled to 720p or lower, as Theora is not efficient enough for full HD delivery at reasonable bitrates.

Kvalita a výkon

Theora is a generation behind modern codecs (H.264, VP9, AV1) in compression efficiency. At equivalent bitrates, Theora produces noticeably lower quality than H.264. To achieve acceptable quality from broadcast MXF sources, higher bitrates are needed — roughly 2-3x the bitrate of H.264 for similar visual results. At 720p with quality 7-8, Theora produces good results for educational and documentary content. For maximum quality from broadcast sources, consider WebM (VP9) instead of OGV if the target platform supports it.

Tipy pro nejlepší výsledky

1Scale broadcast MXF content to 720p before encoding — Theora is not efficient enough for 1080p at reasonable file sizes
2Deinterlace broadcast content before Theora encoding — interlaced source material produces poor results with Theora's compression model
3Use Theora quality 7-8 for the best quality-to-size ratio — quality 9-10 produces diminishing returns with much larger files
4For Wikimedia Commons upload, follow their encoding guidelines: maximum 1080p, Theora quality 6+, Vorbis quality 3+
5Provide a WebM or MP4 fallback alongside OGV for web distribution — Safari does not support Theora playback

MXF to OGV conversion serves the important niche of open-source, royalty-free video distribution from professional broadcast sources, essential for Wikimedia, government open-data, and institutional open-access requirements.

Často kladené otázky

OGV with Theora+Vorbis is completely patent-free, which matters for organizations with strict royalty-free requirements. Wikimedia Commons, some government agencies, and open-source projects prefer or require it. For general distribution, WebM or MP4 provides better quality.

At 720p and moderate bitrates, Theora produces acceptable quality for educational and documentary content. It is not suitable for high-quality broadcast master delivery — for that, use H.264/H.265 in MP4 or VP9 in WebM.

Firefox, Chrome, and Edge support OGV natively. Safari does not support Theora/OGV. For universal web playback, provide an MP4 or WebM fallback alongside the OGV source.

720p (1280x720) is the practical maximum for Theora at reasonable file sizes. Full 1080p requires very high bitrates in Theora due to its lower compression efficiency compared to H.264.

Theora development is essentially complete (stable since 2008). The Xiph.org Foundation has shifted focus to Daala (experimental) and AV1 (via the Alliance for Open Media). OGV remains stable but is not receiving performance improvements.
