YouTube has launched its “Live” channel, offering streaming video in 320p (for now) on a dedicated “Live” video page. There’s lots of potential in the Live channel, (think concerts, video phone chatting, conferencing), but for now only certain YouTube users will be allowed stream content in the beta mode.
First they added 720p HD, then 1080p HD, now YouTube has gone even further by offering 4k HD video. The 4096×2304 resolution format is immense, takes much longer to stream, and can really only be appreciated on high resolution output devices such as a projector or giant TV. You also might crash your PC trying to view the 4k video. But all that doesn’t matter. YouTube has just become “cooler” by launching a resolution higher than even television service providers offer.
