One of the biggest reasons people like this technology is that it has the ability to present a more life-like picture. The edges of each object are very clearly defined, and images move smoothly without interruption. Picture quality is so clear with this feature that it is often compared to viewing unedited film or images from a home video camera — they are sometimes described as being raw and true to life. These same characteristics can be unwanted, too, though, depending on the context.
The feature may also reduce the level of contrast between dark and light colors on the screen, which can change the way certain shapes or characters are perceived. Turn off noise reduction and you'll have more picture detail and a more natural-looking image.
What it really does is artificially boost fine detail and texture, while accentuating the edges of images. At first glance this might give the impression of greater detail, but what it's actually doing is masking fine detail—and oversharpened images can add a halo around objects. So turn it way down or completely off. Note: Some models have a zero setting in the center of the control, so lowering it beyond that point might actually soften the image.
One issue with LCD-based TVs, in particular, is that the image can blur during fast-moving scenes, such as in action movies or sports. TV manufacturers use various technologies to reduce motion blur, including repeating frames or inserting black frames into the video signal. Many companies tie these efforts to another technology, called judder reduction, which is often referred to as motion smoothing. Movies have a slightly stuttering effect, called judder, especially when the camera pans across a scene.
This appearance comes about because movies and a lot of prime-time TV shows are shot at a relatively slow 24 frames per second, or 24Hz. By contrast, video is typically shot at 60Hz. That's why sports, reality and game shows, and soap operas have smoother motion than 24Hz films. Motion smoothing also attempts to reduce judder by increasing the TV's frame rate via a process called frame or motion interpolation.
The TV analyzes adjacent video frames, making an educated guess as to what the in-between frames would look like if they'd been captured, and then inserts those new frames into the video stream. Consider automatically adding frames Auto Motion Plus when the 3D playback frequency automatically increases to The edges of each object are very clearly defined, and the images move smoothly, without interruptions.
But for a small number of frames in the original image an example of viewing analog or SD images , the image becomes very smooth, soap opera. In fact, in order to create an additional frame, a very large computational power of the processor is needed, and if we talk about creating a new frame that shows a dynamic scene with many small details, then we need to use special programs for computing and positioning the object.
Processors in televisions do not have such power. The work of Auto Motion Plus comes down only to the duplication of frames, which is why the effect of soap opera arises. And now more and more video appears at a frequency of 60 frames per second, and old video files shot at a frequency of less than 30 frames per second are adapted modified by the studios using special programs that really draw new additional frames.
I live in a nursing home. We have a Samsung TV in our living room. It is fun to experiment with the auto motion plus setting! Bump it up by one or two notches, give yourself time to get used to the subtle differences, and see what you think—you'll also find the black frame insertion feature in that menu, if your TV has one, and you can use them in conjunction with one another if your TV has a good implementation.
Sony's motion settings are a tad more complicated than other brands, but I've found that turning Cinemotion off, with Motionflow's Smoothness and Clearness both set to 1—the lowest settings for interpolation and black frame insertion—produces the best motion to my eyes. These three settings all interact with one another differently, so you may have to try different combinations to see what you like best. So I'm sorry, Mr. Cruise: I watched Mission: Impossible Fallout with motion smoothing turned on.
It was still awesome, by the way. But, while it's ultimately personal preference, there are still times when I recommend disabling it entirely. First and foremost, you should always turn off motion processing when gaming.
Because the TV has to know the next frame to generate interpolated motion, O'Keefe says, having it turned on will inherently introduce input lag. So you'll get smoother motion, but the controls won't be as responsive, making those boss battles more difficult. That's why your TV has a Game Mode, which turns off motion interpolation alongside lots of other behind-the-scenes processing. In addition, he says, motion smoothing can be hit or miss for sports.
While a lot of people like the added clearness it provides, it can also produce more artifacts in fast-paced play—like a hockey puck disappearing during slap shots.
I've also found certain movies to be more affected by interpolation than others, especially on certain TVs. On my old LG OLED, for example, even low levels of interpolation introduced noticeable soap opera effect on films like Captain America: Civil War , which have scenes that use a strobing effect to minimize motion blur. Other movies, like Spider-Man: Into the Spider-Verse , use clever frame-rate tricks in their animation to tell the story, and interpolation can interfere with that.
So you may want to set up a few different settings profiles you can flip between at will. Ultimately, though, it's all up to you. I'm not here to tell you that motion interpolation on its highest setting is a crime against cinema, nor that pure 24 Hz is a motion-sickness-inducing atrocity. As always, there's a tug-of-war between accuracy and preference, and you're free to do whatever you want with your TV.
