Every few years the processing power of gear has improved enough to let more processor-intensive compression algorithms to be used, and further compress the data without making the image worse. So it's taking the same original (the video), and finding out better ways to make the amount of data less, without sacrificing quality.

In this case, you can basically think of 'better' compression as 'smarter' compression. So the other option is to use better compression. Heavy compression might keep the resolution technically the same, but the image can appear softer, noisier, or have weird distracting artifacts (like those seen to the right).Р”В«ut that's not a great idea if the point is to preserve a director's intent, or show off your new 77-inch OLED. Not great, right? Often that's because the video is highly compressed (either before or during the upload). There are many ways to do this, one of the easiest being reducing the quality. Instead, the video is compressed to reduce the amount of data into a more manageable form. There's no way to conveniently transport it to your home. The amount of raw data coming out the back of a professional HD camera is a massive. This is key if we want 4K/Ultra HD broadcasts (including satellite), 4K Blu-rays, and more.Р”В«ut is it enough, and for that matter, how does it work? Compression (the good, the bad, and the lossy) The idea of HEVC is to offer the same level of picture quality as AVC, but with better compression, so there's less data to deal with.

It's the new successor to Advanced Video Coding (AVC), also known as H.264, which is one of the compression schemes used by Blu-ray.

I'd like to call it H.265, because it sounds cool, but its full name is High Efficiency Video Coding (HEVC).
