The ITU announced today that it’s members have agreed upon a new high efficiency video codec. Dubbed HEVC H.265, the new format is designed to improve on and ultimately replace the current king of all codecs, H.264/MPEG-4 AVC which covers 80% of internet video today.
So far, a lot of attention has been given to the codec’s ability to deliver the same quality video as 264 with only half the bandwidth. That kind of efficiency improvement is a big deal– it could reduce strain on networks and bring high-resolution 4K content delivery over the internet closer to reality.
There are also some important changes for color in the new spec. Recent drafts by the ITU’s Joint Collaborative Team on Video Coding (JCT-VC) have added support for wider color gamuts like Adobe RGB 1998 and 12-bit video. This paves the way for fantastic looking color as wide gamut-capable hardware starts to become more widely available.
Pantone recently announced their color of the year for 2013, a deep shade of emerald green that they call “Emerald 17-5641.” It’s a great color but there’s a catch- most displays cannot accurately show it.
Based on data from Pantone’s website, I was able to plot the color in CIE 1931 (xy). As you can see in the chart below, Pantone’s color is well outside the sRGB/rec.709 color gamut standard used by most HDTVs, the new iPad/iPhone and many desktop monitors. These devices will be stuck showing a version of Pantone’s emerald green that’s less saturated and probably a bit more yellow than the real thing.
This is a perfect example of a popular real-world color that falls outside of the sRGB/rec.709 gamut. Unless you have a monitor that’s able to show wider color gamuts, like the DCI-P3 or Adobe RGB standards, you are missing out on a great color.
