They offer the ability to playback in reverse, so I imagine it's three different formats, doubled so that there's a reverse copy of each video.
If I had to guess, they're probably encoding MP4/H.264, WebM/VP8, and Ogg/Theora.
- jc4p 13y agoSo close: > Note that there are 6 separate encodings -- mp4, webm, and reduced mp4, for forward and reverse
- jffry 13y agoThat makes sense - looks like WebM/VP8 support in browsers is a superset of Ogg/Theora support [1]. It would be silly to serve up Ogg/Theora unless it yielded better quality/bitrate (and I'm not up-to-date on how those two compare in quality at the same bitrate).
