Netflix’s video algorithms team had developed a number of quality levels, or recipes, as they’re called in the world of video encoding. Each video file on Netflix’s servers was being prepared with these same recipes to make multiple versions necessary to serve users at different speeds. ... Netflix’s service has been dynamically delivering these versions based on a consumer’s bandwidth needs, which is why the quality of a stream occasionally shifts in the middle of a binge-watching session. But across its entire catalog of movies and TV shows, the company has been using the same rules — which didn’t really make sense. ... they decided that each title should get its own set of rules. This allows the company to stream visually simple videos like “My Little Pony” in a 1080p resolution with a bitrate of just 1.5 Mbps. In other words: Even someone with a very slow broadband or mobile internet connection can watch the animated show in full HD quality under the new approach. Previously, the same consumer would have just been able to watch the show with a resolution of 720*480, and still used more data.
