On July 9th the ongoing debate between 2K and 4K digital cinema picture resolution took an interesting turn when an unexpected player entered the fray. At VidCon 2010, a conference for online video professionals, came to a close, YouTube announced that they would begin supporting and streaming videos shot in 4K. (And you thought the popular website was only good for short clips of cats riding vacuum cleaners).
Okay granted, this news doesn’t really advance the discussion of digital cinema so much as it raises the awareness of projected image resolution to many industry outsiders who had never given it much thought before. YouTube’s blog post announcing the support of 4K is a perfect example of how the topic is being discussed by the public at large:
To give some perspective on the size of 4K, the ideal screen size for a 4K video is 25 feet; IMAX movies are projected through two 2k resolution projectors.
It was only in December of 2009 that YouTube announced they would allow for 1080p video content to be uploaded and streamed. Less then a year later they are increasing the resolution of the videos they’ll accept by four times to 4096 x 2304 pixels. As a comparison, Sony’s SRX-R320 digital cinema projector has a native resolution of 4096 x 2160 pixels.
