Juddery motion is the bane of home cinema, and one of the main causes of it is when the frame rate of the content you're watching isn't matched by the refresh rate of the TV you're watching it on. This is something that Netflix is looking to address with a new feature outlined on the Netflix Tech Blog.
Without getting too bogged down in mind-boggling science, let's try to explain the problem. Content on Netflix comes in various different frame rates, but the most common is 23.97fps (frames per second), which can be fairly easily rounded to 24fps. TVs in PAL regions such as the UK run at a refresh rate of 50Hz, which means the 24fps signal has to be converted to 50fps before it's displayed.
