It's just above it, in the "Video formats" section.
Ahh.. I guess 'it is necessary to encode your videos in at least two formats.' is the catch there.
It would be nice to know however that iOS is not compatible with WebM considering the media sizing differences.
Eg:
WebM with VP8 or VP9 codec (.webm) (Not iOS compatible)
Ogg Theora (.ogv)
MPEG-4 with h.264 codec (.mp4)
Thanks for the prompt response. Have a great day.
"VIDEO FORMATS
As with audio, browser makers have not been able to agree on one video format that can play everywhere. As a result to guarantee that video playback will work on all browsers and on all platforms, it is necessary to encode your videos in at least two formats.
The Video plugin allows you to set three sources for a video in the following formats:
WebM with VP8 or VP9 codec (.webm)
Ogg Theora (.ogv)
MPEG-4 with h.264 codec (.mp4)
Browsers which support WebM usually also support Ogg Theora, so it is not necessary to specify both a WebM and Ogg Theora source. It should only be necessary to specify a h.264 source and either a WebM source or an Ogg Theora source. Since WebM is a newer and more advanced format than Ogg Theora, it is recommended to specify a WebM and h.264 source.
The Video plugin will prefer to play WebM first if supported and a source provided, Ogg Theora second, and h.264 last."
