One of the indispensable features of TV! What is the role of dynamic smoothing?
Everyone on the new TV will be particularly excited. After all, this is a big piece that can be used for years. Buying a new machine usually means that its technology and features are much stronger than your previous one. Just when you are about to start enjoying the great picture quality, such as putting a movie, you may find something wrong.
Faced with such a sense of violation, some people may feel that high-definition new television is like this, and adapting it does not want it, but this is not a fact. If you find this phenomenon, then this new TV is definitely acquiescence to open a mode - dynamic smoothing. Dynamic smoothing will cause the TV to produce an effect called "soap effect." This function will greatly affect the playback of the video and make the movie's visual effects look terrible.
The evil consequences of this technology may have greater impact than many people think. Even James Good, the director of the movie "Guardians of the Galaxy", recently issued a statement saying that he and Ryan Johnson, Edgar Wright, Tom Cruise and other industry elites have launched the so-called "anti-dynamic smooth motion." After this, many film directors also expressed their support.
The so-called soap opera effect refers to a very unnatural effect caused when a 24-frame movie is played more than this frame. This effect makes it easy for people to think that they are watching a current soap opera.
The vast majority of movies still adhere to the effect of 24 frames, but now it is common for TV to achieve a refresh rate of 60 frames. In order to make the dynamic picture look smoother, TV manufacturers have introduced this technology, although different brands may give it a different name, but it is actually similar. This technique uses algorithms to insert more frames in the video to make up the number of frames, correcting the content of 24 frames to 60 frames to reduce motion blur.
Although this technique is useful in some situations, the extra frames will make the movie look unnatural and fake. After all, the extra information it inserts does not actually exist. Think of colored, black-and-white photos, because they must be artificially guessing what colors are in the original scene. So any color black and white photos will look unnatural. The same is true of television, except that it is artificially added to frames, not colors.
What's worse is that the TV needs to process the content in real time. It doesn't have time to make every frame inserted as perfect as possible, let alone inserting up to 36 frames every second. You may find that dynamically smoothed video looks particularly strange, and this is one of the main reasons.
However, although we have said so many of this feature is not good, and so some celebrities also formed a coalition against it, dynamic smoothing technology is still necessary for television. The place where this feature can be used the most is sports competitions, especially those fast-paced games. Dynamic smoothing is enabled to make the movement of the ball smoother and smoother, without the problem of jittery stalling due to high speed. This time, the game looks more natural.
For many, many years, the film industry has always adopted 24 frames as an industry standard. Even with a small number of challengers, this status remains unshakable. This insistence has also affected television dramas and online video, many of which still remain at 24 or 30 frames. This is not to say that 24 frames are not a good standard in the industry. In fact, many people do think that the movies under this frame rate are the most sensational, but those slow-paced TV series and online videos that have a relatively strong atmosphere are actually many times. The frame of 60 frames is the best.
So at this time, we will need dynamic smoothing to process those videos that are less than 60 frames for us to make it smoother. Even if not everyone likes 60-frame processing, retaining this option is certainly better than not having to choose. Of course, for content that is not suitable for dynamic smoothing, we don't really need to completely turn it off, but we can open it to "minimum" to reduce some of the unpleasant jitters such as lens shift.
So when should we completely shut off dynamic smoothing? When playing games. Although it seems like a great look to make the game look smoother, the fact is that TVs consume more processing power to perform dynamic smoothing, which means that the delay increases, which means that if you press a key, it takes longer to press the key The feedback will appear on the screen. Although this delay will not be obvious to the extent that you can easily notice, if you play those high-tempo games, such as fighting, action, shooting, a slight difference in speed will determine the victory or defeat.
At least for the foreseeable future, dynamic smoothing will exist in the setting options of the TV, and it is indispensable. There is no good way to solve the jitter problem caused by playing 24 frames on a 60Hz screen. Although the future 120Hz TV can alleviate the jitter to a certain extent, when faced with 25 frames of PAL TV format, there will be problems.
According to experts' estimates, to completely solve the problems caused by 24 frames and 25 frames, you need to refresh the TV at a rate of 600Hz. It is impossible for this kind of product to come to market in the short term.
So even if many people hate the function of dynamic smoothing, it is an essential existence. As long as it is used rationally, it will not confuse our experience, and it can even make the video content look better. What TV manufacturers need to solve at the moment is how to make as many users as possible understand what this function means, so as to prevent people from having a bad bad impression on the product itself due to bad perception.
