For that matter, most of the pixels representing their face probably won't change much (other than their lips, of course). The background isn't going to change much for many frames.

In most scenes in a TV show or movie, the vast majority of the frame doesn't change much. How does it do this? Largely by expanding on how AVC (and other compression techniques before it) works.įirst, it looks at multiple frames to see what doesn't change. With each jump, the general rule is half the bit rate for the same quality (or greater quality at the same bit rate). Not wanting to mess around with small, incremental improvements, whenever a new compression standard is introduced, it has to be a sizable change. While most of us were just getting used to the idea of H.264's advantages over MPEG-2 on Blu-ray, the Motion Picture Experts Group and the International Telecommunication Union's Telecommunication Standardization Sector (ITU-T) were already starting work on the next generation of video compression, with an eye on the future. passive 3D: What's better?Īs data-intensive as HD is, 4K is even worse. You can do it with more compression (reducing the apples to sauce), or with better compression (finding a better way to make them all fit, but preserving their appleness).īetter compression: more apples, same spaceĪs you can see from this delicious example, 'more' compression is easy (SMUSH) while 'better' compression requires more thought and/or better technology. You can decrease the amount of data required for a signal either by cranking up the compression and making the image ugly (just 'more' compression), or using a more efficient compression technique ('better' compression). This distinction between 'more' compression and 'better' compression is important, as really, the terms aren't interchangeable in this context. 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).īut 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.īut 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).
