YouTube transcodes all its videos to WebM / VP8, H.264 still supported
We did know that Google is really in love with WebM since it added support for it and its codec, VP8 in Chrome. Now, Google is ready to take it one step further and begun a huge effort of converting their entire video portfolio (and we have no idea how many terrabytes of data that is – 6 years of uploads to WebM as well. Higher priority will have the files with more views and, like in everything else, the top 10% will get 90% of traffic. Until now, about 30% of the files are already converted through the usage of a cloud video processing infrastructure that can use massively parallel computer networks to spread the converting tasks around.
The new uploads will be automatically converted to WebM but the popular (and iOS favored) H.264 format will also be supported and continue to serve the tens of millions iPad, iPhone and iPod users.
