About ASF to OGV Conversion
OGV (Ogg Video) uses the Theora video codec and Vorbis audio inside an OGG container: a fully open-source, royalty-free video format championed by the Xiph.Org Foundation. Converting ASF to OGV moves Windows Media content into an open format that was once the standard for HTML5 video on Firefox and Wikipedia before H.264 gained universal browser support.
Why Convert ASF to OGV?
OGV is required by platforms that mandate open-source, royalty-free media formats — most notably Wikimedia Commons, which only accepts OGG/OGV/WebM for uploaded media. Some Linux-based embedded systems and kiosk applications also require patent-free video formats. If you need to contribute ASF video to Wikimedia or deploy on systems with strict open-source licensing, OGV is the appropriate target.
Common Use Cases
- Uploading ASF video content to Wikimedia Commons in their required open format
- Converting ASF recordings for playback on Linux systems without proprietary codecs
- Preparing ASF content for open-source CMS platforms that prefer OGV for licensing reasons
- Creating royalty-free video assets from ASF sources for open-source documentation
- Deploying ASF video on embedded Linux devices that only support Theora
How It Works
The ASF container is demuxed, and the WMV video stream is transcoded to Theora using libtheora. WMA audio is re-encoded to Vorbis. Theora uses block-based DCT compression similar to VP3 (its predecessor). Quality is controlled via a 0-10 scale. The OGV container interleaves video and audio pages using OGG's granulepos-based timestamp mechanism.
Quality & Performance
Theora is less efficient than H.264 — at the same bitrate, H.264 produces visibly better results. Theora at 2-4 Mbps provides DVD-quality video at standard definition. For HD content, bitrates of 6-10 Mbps are recommended for acceptable quality. OGV files will generally be larger than equivalent MP4 files.

Tips for Best Results
- 1Use OGV only when a royalty-free format is explicitly required — WebM or MP4 are better for general use
- 2Set Theora quality to 7-8 for acceptable HD quality, but expect larger files than H.264
- 3For Wikimedia Commons uploads, follow their specific encoding guidelines for resolution and bitrate
- 4Consider converting to WebM instead of OGV if your target platform supports it — VP9 is dramatically more efficient than Theora
