If you've just bought a new TV, you might be wondering why everything you see feels incredibly fast and supple You watch a TV broadcast live all the time. You do not imagine things: your television may be suffering from Motion Smoothing .

What is Motion Smoothing and how does it work?

Every TV maker calls his special technology under a different name for marketing reasons, of course. Action Smoothing, TruMotion, Motionflow: These are names for the same function: The image of your TV feels softer. And that is motion smoothing. It is also known as the "soap opera effect" because cheap soap operas used to have inexpensive video cameras that provided a higher frame rate and softer looking video.

Most telecasts, movies, and programs are shot at 24 or 25 years old, 30 frames per second (fps, also called "hertz" or "Hz"), which is fast enough for the eye to see them as smooth video and not perceived as a choppy slideshow. However, most televisions and monitors default to 60Hz, and some more expensive displays clock at 1

20Hz and even 240Hz.

But movies and TV shows are still 30 frames per second, which presents a problem of 60Hz when displayed the displayed content is only half updated? The refresh rate of movies does not change that fast, so "Motion Smoothing" comes into play here. Motion Smoothing attempts to resolve this issue by estimating the 30 frames missing each second. Here, a before and after is shot compared and tries to find the middle ground between the two.

Why is it such a problem?

19659005] Most people have problems with motion smoothing. After all, we spent years training our brains to enjoy movies and TV programs filmed at 24 or 30 frames per second, and our brains think a movie or TV show should be.

TV manufacturers On the other hand, they only try to send consumers larger numbers. 240 Hz must be better than 120 Hz and much better than 60 Hz, right? Well, sometimes it is like that – especially if the content is designed for it.

But most consumers do not enjoy the higher frame rates of most content they see. Content filmed at 24 or 30 frames per second is particularly funny on TVs running at 120 Hz or more. The incredibly gentle movement makes the video seem almost real, which completely breaks the immersion of the cinema. Honestly, it often feels more like seeing a documentary about the movie behind the scenes than the movie itself.

For some things, smoothing the movement makes sense. For example, live action sports and video games have fast-paced content that needs a bit more clarity. Unfortunately, two other problems associated with smoothing the motion solve these two applications.

  • In sports, sometimes things move so fast that the smoothing algorithm does not know what to do and creates a strange, often blurry image instead of a clear "in-between" frame. This error, which results in erroneous images, is referred to as Artifacting .
  • In video games, the extra input delay required to smooth out the movement is completely ruined, so the game can be effectively played. The controller feels sluggish and unappealing, which is why most televisions offer a "game mode" that disables smoothing of movement and other advanced image effects.

And other types of content, such as cable TV or reality TV, can still look eerie "cinema".

Do I have it? How can I get rid of it?

You'll probably find out if your TV has been activated. If you have a newer brand called TV, Smoothing may be on by default. Most of the time, the option to turn off the picture settings in the menu is hidden. However, if you can not find them, read our instructions on disabling the effect for Samsung, LG, Sony, Vizio, and Roku TVs.

Otherwise, consult the manual and support website for your TV.
