It's always nice to discover that you have something in common with Tom Cruise – and it turns out What Hi-Fi? is fond of motion smoothing, or interpolation, (more regularly referred to as "movement" processing & # 39;) as the star Top Gun .
In a bizarre but brilliant tweet, The Cruiser released a video in which he and Mission: Impossible – Fallout director Chris McQuarrie make a passionate request to turn off the TV movement before watch their (or other) movies.

This is good advice, we have prepared the instructions that will help you disable the motion control of almost all TVs, from LG to Samsung to Sony.
But it is worth pointing out that not all the leveling of the movement is bad and there are some implementations that are worth leaving active, at least in part.
But first, what is the leveling of the movement, and why does it also exist?
What is the leveling of the movement?
Motion leveling, also known as motion interpolation or motion processing, is a technology incorporated into most modern TVs designed to reduce flicker and blurring from video sources.
Usually works by introducing artificial video frames between the actual frames provided by the source. It's exceptionally smart when you think about it, but why do you want to insert additional frames into the video you're watching?
It is because the frame rate used for many content is actually quite low: 24 fps for almost all movies and most of the TV shows with scripts. It is quite slow that with a fast movement an object or a person can jump from one point of the screen to another a few pixels away.
Your eyes often perceive this as any combination of flickering, blurring or bizarre artifacts around the subject in question, depending on the speed of movement and the TV's native response time.
Any TV can display much more than just 24 frames per second, though. In fact, they naturally show 50 frames per second in countries such as the United Kingdom that have a network frequency of 50Hz. In other countries such as the United States, a network frequency of 60 Hz results in the display showing 60 frames per second. Many TVs now update each frame at twice the speed, while others expect to triple it or more (though they often do not).
Most of the sources designed for 24fps output actually speed up the video at 25fps for better synchronicity with a 50Hz TV, but still leave the television with two possibilities: view each frame twice or add a frame from those he receives to bridge the gap. The first choice may result in a little flicker and / or blur, while the second is the interpolation (leveling of the movement) that Cruise warned.
The crux of levitating movement is that it can cause unnatural movement, which in its worst cases is often called the "soap opera effect". It may be hard to pinpoint exactly why this type of movement looks "wrong", but generally there is a feeling of overcrowding, things that move artificially quickly and / or strange artifacts that appear around fast-moving objects. movement.
These problems are created because the TV essentially provides, with an exceptionally high speed, what will be the next "real" frame and will invent a frame that is halfway. Consider everything that happens in every single frame of a movie, and that's great. Inevitably, TV often misses the elements and this can cause the defects described above.
But while we are in agreement with Cruise, the improvement of the movement is often turned off, it is not always the case. In some cases, switching from the default mode to a slightly less aggressive mode can result in a useful reduction in vibration or blurring without damaging the naturalness of the image. Only one manufacturer, meanwhile, offers its televisions with predefined motion settings that we usually recommend leaving as they are.
And for what it's worth, we do not believe (as some seem) that the processing of the movement of a TV should be turned on for some sources and turned off for others. If the leveling of the movement is not good enough for the films, it is not good enough for nothing else for us, including sport.
Fortunately, it's actually quite easy to turn off motion control by flicking through the settings menu image until you find an option with "movement" in the name: we've listed the name (s) used by each manufacturer below.
Regardless of whether you simply disable the function it is slightly less simple, however, thanks to the variation in the native refresh rate, response time and the implementation of the leveling of the movement between the models of each manufacturer. Of course, we can not list all the models of all brands here.
In addition, personal taste manifests itself in this: some people find the natural vibration of a 24 fps presentation that distracts while others barely notice, and some people are particularly sensitive to the peculiar nature of interpolation.
For these reasons, you should not simply do what we – or Tom Cruise – recommend. Instead, find the relevant settings or settings as described below and try turning them on and off to see what works best for you. To help, here are two of our favorite clips to test the movement:
Guardians of the galaxy Vol.2
L & # 39 ; opening scene sees Ego and Meredith (Kurt Russell and Laura Haddock) driving through the Missouri countryside. He pays particular attention when Meredith protrudes her arms from the open roof of the car: most of the processing of the movement has a real problem in distinguishing her arms from the rapidly moving scenery behind and flicker or vanish altogether.
So look at the car that enters the Dairy Queen: you may see shadows and / or blurs, depending on the specifics of your TV and the mode of processing the movement you have selected.
Harry Potter and The Order Of The Phoenix
Within the first minute about this entry in the series by Harry Potter provided two difficult panning shots; one vertical and one horizontal. With the horizontal panorama, pay attention to the complicated motif created by long grass, observing the addition of unnatural artifacts by any processing of the movement.
You could also see some oscillator here, but it's the vertical box, a high-rise shot of the city and park, this is the real test of judder and blur. Experiment with the settings of your TV until it feels right, paying attention to the flow of machines that move through the image.
How to Disable Smoothing Motion on a Hisense TV
Setup: Ultra Smooth Motion
Hisense televisions suffer more than most Judgers when motion smoothing (called Ultra Smooth Motion) is completely turned off, so we generally opt for the Medium setting. This often involves a slight, unnatural, excess of movement, of which Mr Cruise would not approve. For us it is the best compromise (or less).
Some Hisense models, including recently reviewed AE6100UK models, have no motion leveling options at all, in which case you get what is given to you.
How to disable the leveling of the movement on an LG TV
Sony is the strangest here, because its leveling of the movement is generally so good that it is worth leaving it on. The setting is called Motionflow and in most cases it is set to Standard by default. In our experience the result is a degree of sharpness and smoothness that maintains the natural appearance of the image and does not introduce artifacts.
There are exceptions, of course, and some low-end models will be better served by turning it off completely, but with most Sony models, even Maverick would be happy with Motionflow.
