Is this what gfycat does?
- dublinben 12y agoThat site actually uses the superior VP8 compression format in a WebM container.
- wlesieutre 12y agoExcept for being free, WebM was not a "superior compression format" to H264 last I heard. Has it changed recently?
- higherpurpose 12y agoI think it all but caught up lately in VP8 vs h.264 performance. Google kept improving VP8 performance. However, webm has also added VP9 support recently, which is clearly superior.
- wlesieutre 12y agoIs VP9 in much use (compared to VP8)? I've definitely heard good things about it, but I have no idea how well supported it is or whether anybody has it in use yet.
- fleitz 12y agoOh does my iPhone have a VP9 chip in it? Not so superior...
- bqe 12y agoThis is not true. My work, written three years ago, showed that VP8 was inferior to H.264[1] at the time. A more recent paper showed that both VP8 and VP9 are inferior to both H.264 and HEVC[2].

- dallen33 12y agoSuperior in what sense? Not quality or file size.
- valarauca1 12y agoWebm is superior to gif in terms of quality AND file size. (Other video formats, not so much).
- runeks 12y agoSuperior to GIF.
- tormeh 12y agoWell, it's patents are free to licence and with open source code, so it's superior in a way that for many (me included) believe trump the others.
- waterhouse 12y agoPedantry: WebM is not a compression format. It is a container format. At the moment it appears to support VP8 video, VP9 video, Vorbis audio, and Opus audio; there is no single form of compression that WebM implies.
