What to expect
- Video is re-encoded to Theora or VP8 and audio to Vorbis or Opus, so expect a lossy result, not a copy.
- OGV is royalty-free and plays in Firefox and Chrome, but most phones and editors reject Theora.
- DRM-protected M4V cannot be converted, and the efficiency of the open codecs may differ from the H.264 source.
Frequently asked questions
Is M4V to OGV lossy?
Yes. H.264 video is re-encoded into the Ogg container's Theora or VP8 video, which is a lossy generational step. The audio is likewise re-encoded to Vorbis or Opus, so the OGV is a fresh encode rather than a copy of the source.
Why convert M4V to OGV?
OGV is a royalty-free, open container from Xiph.Org, so the conversion suits projects that need a patent-free video format. It also plays natively in Firefox and Chrome for embedding in web pages.
Where does OGV open?
OGV plays in VLC on any desktop OS and natively in Firefox and Chrome. Most phones and many video editors do not accept Theora, so support is narrower than for MP4.
Can a protected M4V be converted to OGV?
No. FairPlay-protected iTunes M4V files cannot be transcoded; only DRM-free M4V will convert to OGV.
