Do you want to see 4K video in action? Phil Holland has put together a rather good demo clip, captured using a 6K RED camera and encoded using VP9 at 4K resolution (3840 x 2160 pixels).

The clip is 1 minute 55 seconds, 200MBytes in size, which works out at around 13Mbits per second. To view it for yourself, download the Zip file here, extract the .webm file from the Zip file, and drag it into a Chrome browser window. Of course, you'll need a 4K resolution monitor to get the full benefit and you may need a fast processor for smooth playback.
