Youtube has gone beyond the 1080 HD videos which is still not very common on many consumer electronics devices today. Youtube has announced at the VidCon 2010 conference that they will now support a massive 4096×3072 pixel resolution of super HD videos and content on their website.
To achieve 4096p resolution, Youtube has increased pixel density by 600% while on the downside it has increased bitrate by only 25% on 1080p resolution to reduce the video file size. Because of the lower bitrate, the videos might not show true 4096p but will be definitely better than 1080p videos. Although, Youtube has said in future they will increase the bitrate which will automatically increase the file size and will need very fast broadband speeds.
Youtube’s previous supported a maximum of 1080p HD videos which was announced in December last year and in just little more than seven months they are supporting four times 1080p resolution which is really huge. According to Youtube blog, the ideal screen size of watching 4096p HD videos is 25 feet while IMAX movies are projected through two 2k resolution projectors.
Here is a snippet from Youtube Blog.
Because 4K represents the highest quality of video available, there are a few limitations that you should be aware of. First off, video cameras that shoot in 4K aren’t cheap, and projectors that show videos in 4K are typically the size of a small refrigerator. And, as we mentioned, watching these videos on YouTube will require super-fast broadband.
We’re excited about this latest step in the evolution of online video. We’ve been impressed by the 1080p videos you’ve uploaded over the last seven months and can’t wait to see (in 4K!) what you do next.
To view the video in more than 1080p resolution you just have to select “Original” in quality drop down menu. Below are the five videos from Youtube’s playlist which gives you a glimpse of how a 4096p resolution video looks like.
