How to disable the leveling of the movement on the TV – What Hi-Fi system?


It's always nice to discover that you have something in common with Tom Cruise – and it turns out Which Hi-Fi? is passionate about smoothing movement, or interpolation, (more regularly referred to as "processing of the movement") as the Top Gun star.

In a bizarre but brilliant tweet, The Cruiser published a video in which he and Mission: impossible – Fallout director Chris McQuarrie makes a passionate request to turn off the TV movement before watching their (or other) films.

Since this is good advice, we have prepared instructions that will help you disable motion control of almost any TV, 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 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 the flicker and blur of video sources.

It generally 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's 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 native response time of your TV.

However, any TV can display much more than 24 frames per second. 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 claim 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 leaves the TV with two choices: view each frame twice or add a frame between those he receives to fill the gap. The first choice may involve some flicker and / or blur, while the second is the interpolation (smoothing of the movement) that Cruise warned.

The crucial point of the case against the leveling of the movement is that it can cause an unnatural movement, which in its worst cases is often referred to as the "soap opera effect". It may be difficult to point the finger exactly on why this kind of movement looks "wrong", but generally there is a feeling of overcrowding, things that move artificially quickly and / or strange artifacts that appear around objects in rapid 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 flaws described above.

But while we are in agreement with Cruise that the leveling 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 generally recommend leaving as they are.

And for what it's worth, we do not believe (as some seem) that the processing of a TV's movement 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 disable motion control by flicking through the image settings menu until you find an option with "movement" in the name: we've listed the name (s) used by each manufacturer down.

If you simply disable the function it is slightly less simple, however, thanks to the variation in the native update 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.

Furthermore, personal taste comes in this: some people find the natural vibration of a 24 fps presentation that distracts, while others are barely aware, 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

The opening scene sees Ego and Meredith (Kurt Russell and Laura Haddock) driving through the Missouri countryside. He pays special attention as Meredith pulls her arms out of the open roof of the car: most of the processing of the movement has a real problem in distinguishing her arms from the fast moving scene behind and flicker or vanish altogether.

Then look at the car that enters the Dairy Queen: you may see some vibrations and / or blurs, depending on the specifics of your TV and how you have processed the motion you have selected.

Harry Potter and the order of the phoenix

Within the first minute about this item in the Harry Potter the series provided two difficult panning shots; one vertical and one horizontal. With the horizontal panorama, pay attention to the complicated motif created by tall grass, observing the addition of unnatural artifacts by any processing of the movement.

You could also see some judder here, but it's the vertical pan, a header from the city and the park, this is the real test of judder and blur. Experiment with the settings of your TV until this seems right in your eyes, also paying attention to the flow of machines that move through the image.

Hisense H65AE6100UK does not actually have a motion leveling function that can be turned off

Setting: Ultra Smooth Motion

Hisense televisions suffer more than most users when the motion smoothing (called Ultra Smooth Motion) is turned off completely, so we generally opt for the Media 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 the least bad).

Some Hisense models, including recently reviewed AE6100UK models, have no motion smoothing options, in which case you get what you are given.

How to disable the leveling of the movement on an LG TV

The LG motion leveling function is called TruMotion

Setting: TruMotion

The motion leveling setting of LG TVs is called TruMotion and you will find it hidden deep in the image setup menus. It is set too high by default (Clear is usually pre-selected) and many people will find that simply turning it off gives them the most satisfying movement.

That said, others will appreciate the User mode, which allows a subtle adjustment of the "dejudder" and "deblur" settings. Two to three points on each of these offers movement that some people – some of our reviewers included – prefer.
