In a single pixel of 1080p video, there are now 4 pixels at that same location when shooting with 4K video. So this is where 4K comes in to improve existing 1080p video. 4:2:2 is slightly better than 4:2:0, but it is till not as good as uncompromised 4:4:4. Some cameras that are being launched today are coming with the ability to capture 4:2:2 video with an external recorder. And although we have reached a point in our consumer electronics to handle the data of 4:4:4, there really isn’t any push to improve 1080p video recording. Unfortunately, all consumer video recording devices have conformed around the idea of 4:2:0 chroma subsampling and never looked back. However, as our technology and tastes improve over time, we see that 1080p video, still has a fairly large room for improvement. No Consumer Demand To Improve 1080p Video RecordingĮven with chroma subsampling, 4:2:0 1080p video still looked good enough to be called HD just a few years ago. It is how every smartphone, pocket camera, slr camera, and even most video cameras record video today and probably will continue to do until the foreseeable future. This is known as 4:2:0 chroma subsampling. What this means is that 75% of the color information is discarded but the benefit is we are left with 50% less data. And what engineers have figured out is that as long as we keep the luma (aka brightness) information of each pixel, we can share the color data of one pixel data with 3 neighboring pixels. However since we’re dealing with 2 million pixels, that is quite a bit of data. In a perfect world, every pixel should have it’s own Y, Cb, and Cr value.

And the two chroma values Cb andn Cr that tells us what color the pixel is. The luma value Y that tells us how bright that pixel should be. Let’s zoom into a single pixel, which is made up of 3 different pieces of data. It is approximately 2 million individual dots of color. To understand what chroma subsampling is, let’s imagine a grid of pixels representing 1080p video. It is due to a limitation brought on by chroma subsampling in the 1080p video on the left. When you compare the 100% crops of 1080p video straight out of the Galaxy Note 3 or any smartphone or even a dedicated video camera compared to 4K video resampled at 50% of it’s original sized (interpolated 1080p video), you should be able to see a big difference in quality.

However, what makes phones that can capture 4K video like the Galaxy Note 3 so revolutionary is that we are finally able to overcome the limitations and produce real 1080p HD video, at a higher detail than even a lot of professional video recorders. Have you ever wondered why 4K videos look so much better than 1080p videos, even on your 1080p monitor? The answer is more than “too much compression.” The loss in detail is due to a practice called chroma subsampling and how it has been limiting a limiting factor on virtually all 1080p video that has ever been captured on a smartphone or even on professional DSLRs.
