YouTube experimenting HD with H.264
After the launch of the live service and of entire movies, YouTube’s engineers are experimenting the delivery of HD videos using H.264.
These are examples of YouTube HD (Requires Flash Player 9):
The video has a resolution of 1280×720 (720p HD) and is encoded @ 2.2Mbit/s.
Not bad, but the bitrate/quality ratio can be widely improved as is known by who reads my blog and has watched my experiments of HD videos at low bitrate.
I think that the effort to keep low the bandwidth requirements with good quality is very strategic for the effective diffusion of HD on the Internet. This is why I’m in the endless quest for techniques and best practices to push H.264 encoding to the limit.
Here I repost some well-known examples:
