For instance, if a ball is on the left side of the screen in frame A, and the right side of the screen in frame B, the TV could safely assume that if there was a frame between A and B, the ball would be in the center of the screen.Ī 120Hz TV determines what this "AB" frame would look like, then inserts it between frames A and B. The processing in modern TVs can determine, with a surprising amount of accuracy, what happens in between two frames of video. Motion interpolation: What causes the soap opera effect You need something to change to, and that's when things get interesting. The images are still being held, and if you just double the number of still images to fit 60 into 120 you haven't really changed anything. Higher refresh rates don't, in and of themselves, fix the motion blur problem.

Modern 4K TVs max out at 120Hz, but in the 1080p days, there were models up to 240Hz (or 100 and 200Hz, depending what country you live in).
It's the main reason for higher refresh rates. TV manufacturers have known about the motion blur issue for years. Samsung's name for its motion interpolation tech.ġ. Here are the pros and cons of four potential motion blur solutions. Today's TVs have a number of solutions for reducing motion blur, none of which is quite satisfactory. The physiological reasons behind this are beyond the scope of this article, but the key aspect is that motion blur is in your head (isn't everything?), which is important when it comes to discussing how we get rid of it. Your brain and eyes, expecting smooth motion, blur the object by moving to follow where it should be. It's actually stationary and then jumps to the next position, which is also stationary. The images are held long enough that your brain assumes anything in motion is going to continue being in motion… but it isn't. However, your brain is working fast enough that it's expecting to see motion during those hold times. You don't see still images, you see fluid motion. Sixty still images every second is fast enough to exceed your brain's flicker fusion threshold. Your brain on LCD TV motion: The blur is in your head Some TVs have faster refresh rates, and in some countries TV refresh every one-fiftieth of a second, but the process is the same. Then the screen refreshes and a new image is held there for another one-sixtieth of a second.

With most TVs this means that for a full one-sixtieth of a second, the image is stationary on screen. LCDs - and modern OLED TVs - configure their pixels to show an image and then hold that image until the screen refreshes. These days most LCDs are able to change their states fast enough that motion blur is caused by something else: " sample and hold." In the early days of flat TVs and displays, the culprit was often the slow speed of the liquid crystal elements that create an image on LCD TV. Note how the lower 1.5 dolphins are softer than the others. There's also blur caused by the TV itself, which, to an extent, you - actually, your TV - can do something about.Ī still photo edited to mimic motion blur. Some of this can be attributed to the lower frame rate of movies and most TV shows, which can result in a blur caused by the camera. One second you're seeing every eyelash and wrinkle, the next it's a blurry mess. I always notice it when there's a closeup of a face, and then the person turns away. This can be a single object, like a ball or car, or the entire screen, as when the camera pans across a landscape. Motion blur is when anything on-screen blurs, becoming fuzzy and less distinct, when it moves.
