What actions can you do with slow mo? How to make Slow Motion video (slow motion effect). Comparison of time-lapse quality on different iPhone models

The slow motion effect is often used in cinema when it is necessary to show interesting moments in more detail and effectively. Equipment that allows you to shoot slow motion costs a lot of money. However, the result is really cool. Using special designs with cameras, operators achieve a slow motion effect (by changing the shooting angle).

The slow motion effect can be achieved in a more budget-friendly way. Thus, more and more modern flagship smartphones support Slow Motion technology. People slow down tricks on skateboards, jumping into water, raindrops - everything possible. Not surprising, because this is an interesting feature that is convenient to use.

How to create the slow motion effect

Slow motion is achieved by increasing the number of frames per second. This is why you often hear the phrase “120/240/960 fps”. The recorded “slow motion” video is played back at a frequency familiar to the human eye, for example, 30/60 frames per second. In this regard, 1 second of the filmed video is stretched in the final slow-motion video by 2.3, 5 or more. However, we must remember that when shooting in slow motion with a smartphone, the image resolution usually decreases. Therefore, it is recommended to shoot such videos in good lighting conditions, for example, outdoors in clear weather. This way the loss of quality will be almost invisible.

The higher the frame rate, the more you can slow down the moment. Today, among phones, the Samsung Galaxy S9 camera has the highest frequency. Its value is 960 frames per second. For professional cameras, this number can increase to several hundred thousand.

How to make Slow Motion from a regular video

Achieving the slow-motion video effect is very easy, even if you don't have an expensive camera or phone that shoots such videos. Of course, to achieve the best effect, it is advisable that your smartphone camera shoot video at 60 FPS (frames per second), but the standard 30 is also quite suitable. We will use the Movavi video editor program, since it has a special tool for our task.

First of all, download, install and launch the Movavi Video Editor program. Next you need to add records to the program. To do this, click the “Add Files” button or simply drag and drop the video onto the timeline. You can add several fragments at once, for example, if you want to make a video with slow motion moments from different parts.

In the program, you can slow down both the entire video and a specific section of the video. So, a filmed jump on a skateboard can be slowed down only at the moment of flight, so that the effect is even cooler. To do this, you need to cut the video at the beginning and end of the desired moment. On the timeline, click on the desired break location and click on the “cut” tool (the “Scissors” icon right above the timeline).

Double-click on the desired fragment and the tools menu will open. Among them, find the “Slow Motion” option. By changing the position of the slider, select the optimal speed for the video. By the way, here you can make sure that the length of the video increases. The lower the percentage on the slider, the longer the fragment on the timeline.

After you have set the duration, if desired, you can remove the audio track and add musical accompaniment. This way you will get rid of distortion of the original sound and add impact to the video. After editing, save the result by clicking the “Save” button and choosing a format.

Create videos with slow motion effects yourself

Happy creativity, friends, with the Movavi video editor!

All modern iPhones have a colossal number of functions that users sometimes are not even aware of, but this is a technologically advanced and rather expensive device. Today we will talk about such a wonderful feature as the slow motion mode: which devices it is available on, how to use it all and what settings you can tweak.

Since the iPhone 5s, all Apple smartphone models can record video at 120 frames per second, but only the latest versions equipped with the A11 Bionic and A12 Bionic chip, such as the iPhone 8, iPhone X, iPhone XR and iPhone XS, can record Slo -Mo video in Full HD resolution (1920 × 1080 pixels) at 240 fps.

Comparison of time-lapse quality on different iPhone models

By default, iOS devices record Full HD video at 120 fps, but the settings can be changed if desired. Note that the ability to shoot Full HD video at 240 fps is present only in the iPhone 8, iPhone X, iPhone XR and iPhone XS; earlier models only support video recording in 720p resolution (1,280 × 720 pixels).

• iPhone 5s - 720p (1,280 x 720 pixels) at 120 fps;
• iPhone 6 and iPhone 6 Plus - 720p at 240 fps;
• iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7 and iPhone 7 Plus - 1080p at 120 fps or 720p at 240 fps;
• iPhone 8, iPhone 8 Plus, iPhone X, iPhone XR, iPhone XS and iPhone XS Max - 1080p at 120 or 240 fps.

Recording 1080p/240fps video requires the H.265 (High Efficiency Video Coding) codec built into the Apple A11 Bionic microprocessor or higher.

On which devices can you view slow-motion videos shot on an iPhone?

Full HD video recorded at 240 fps can be viewed on any device compatible with iOS 11 or macOS High Sierra 10.13 or later, although high-quality playback may require a modern iPhone or Mac (iPhone 6 or later) , iPad Air 2, Mac models released since mid-2015).

You can watch slow motion videos on your iPhone just like any other video. All iPhone models, starting with 4s, are equipped with a 60 Hz screen, so any video with a high frame rate is played back without loss of quality. For high-quality playback of recordings on desktop computers (based on macOS or Windows), you will need devices equipped with a 6th generation Intel Core processor or lower.

However, the best way to watch videos is on the iPad Pro. All 2017 models support, providing an image refresh rate of up to 120 Hz. When playing 1080p/240fps video on an iPad Pro that supports this technology, the screen refresh rate will automatically increase to 120Hz for smoother, clearer playback.

How much space does slow motion video take up?

Thanks to the efficiency of the H.265 (HEVC) video codec, 1 minute of recording in Slo-Mo mode (1080p/120 frames per second) takes about 170 MB of memory, 240 fps - 480 MB.

How to Record Slow-Mo Video on iPhone (1080p/240fps)

1. Open the application "Settings" on a smartphone.

2. Click option "Camera".

3. Select a subsection “Slow down. video".

4. Select the slow motion quality.

Advice. To display the hidden option to record 720p video at 240 fps on modern devices, switch from format High efficiency on Most Compatible V "Settings" - "Camera" → "Format". The camera format menu does not appear on unsupported devices.

5. Close "Settings" and run the application "Camera".

6. Select an option "Slow" at the bottom of the interface.

Advice. iOS can remember the last used mode, for example, “Video” or “Photo”. To do this, open "Settings" → "Camera" → "Save settings" and switch the option toggle switch "Camera Mode" into position "on".

7. Click the button "Record" or the volume key to start or stop recording.

The recorded video will be saved in the application "Photo" as a file with the extension .MOV.

Accelerated videos and Slow-Motion have recently become mainstream. Posting an ordinary video on VK or Instagram means showing that you are behind the times. But if everything is more or less clear with accelerated shooting, then how to make high-quality Slow-Motion? My nephew asked me this question last weekend. Unfortunately, my old Samsung model was not capable of creating high-quality video with a slow-motion effect. Will your smartphone, tablet or camera cope with this task? Let's figure it out together.

Frame frequency

The first place to start learning slow-motion is the frame rate. It is measured in fps - the number of frames per second. Modern smartphones can offer 120 fps, iPhone 6 reached 240 fps. How much do we need for slow motion? The average frequency of the videos we watch on TV or online is 24 frames per second. It is at this speed that our brain stops identifying frames as separate, disconnected pictures and perceives them as movement.

How to shoot a video slowed down in half at 24 frames per second? It's very simple, you need a camera with a frame rate of at least 48 fps. But a video slowed down 2 times is not quite slow-motion: most users strive to achieve 5-10 times slowdown. Accordingly, the required frame rate increases. Therefore, offers of amateur cameras with a frequency of 1000 fps or more are appearing on the market.

For slow motion photography you need a “high-speed” camera and a low shutter speed

The effect of slow motion also directly depends on the shutter speed setting. When we shoot regular video, we use a shutter speed of 1/48 at a speed of 24 fps. This level will add some blur to the frames and make the motion effect more natural to the human eye. But if we want to get slow-motion video, then a shutter speed of 1/48 at an increased frame rate will give us strange blurry images in the video. Therefore, we use the rule: the shutter speed denominator is calculated as 2 x fps. That is, if we shoot a video for a 2x slow motion effect at a frequency of 48fps, then we set the shutter speed to 1/96.

But there are pitfalls: the shorter the shutter speed, the less light hits the matrix. Hence the conclusion: you can shoot at a frequency of 120fps or more either in bright natural light or using lighting devices.

How to spot a fake slow-motion effect

Is it possible to “stretch” video with a frequency of, for example, 96 and 120 fps by 8 or even 10 times? Theoretically, this can be done in the editor. But if the final frequency is less than 24fps, then the video will “disintegrate.” You will see a slow transition from one frame to the next. Have you decided to take this step? I advise you to use the Twixtor plugin: it will complete the missing frames and return the effect of natural movement.

In addition, the main advantage of slow-motion is in the details that elude our sight in life and in regular video. Therefore, high-quality slow-motion at home can be obtained with a frequency of 240fps (congratulations to iPhone 6 owners). Well, for a professional video that is worthy of decorating a Youtube channel, you need at least several thousand fps.

Finally, here's an example of some quality time-lapse photography from the Slow Mo Guys.

Slow-motion as a simulation of strong emotions and stressful situations

Changing the perception of time depending on the emotional state is a known thing. It seems to us that the emotionally rich moments of our lives last longer than they really do. For example, when a person feels a threat to his life, time begins to flow noticeably slower. This illusion occurs due to the brain being overloaded with incoming information.

In 2007, American scientists conducted experiments that made people really scared. They dropped several volunteers from a height of 50 meters onto a special net without insurance, and even with their backs forward. As a result, it was found that the feeling of “flight into the abyss” was at least a third longer than what actually happened.

In addition, in a frightened person, the amygdala begins to actively work - a part of the brain that accumulates a kind of secondary set of impressions. “As a result, memories of any terrifying events become deeper and stronger,” the scientists explained. “And the more information about them is stored in your memory, the longer they seem to you later.”

Slow-motion is achieved by shooting at frame rates higher than the standard 24 frames per second. It is believed that slow-mo was invented by the Austrian priest and physicist August Musger. It was he who developed the technique of slow motion using a mirror drum as a synchronization mechanism. The device he used was patented in 1904 and first presented in a cinema in Graz in 1907.

It can be assumed that slow motion video provides the opportunity to accumulate additional impressions of what is happening on the screen in memory, allowing you to enjoy a richer experience for a longer period of time. In other words, by watching a scene in slow motion, we can remember more details, just as we do during moments of stress and adrenaline rush in real life.

This idea may explain the particularly frequent use of slow motion in dramatic scenes. Soviet classic Vsevolod Pudovkin used slow-mo in the dying scene in 1933's The Deserter, in which the hero jumps into a river. The first American film to use slow motion was Bonnie and Clyde in 1967. The scene in which the main characters were caught in a hail of bullets on a country road was remembered by the audience for its particular cruelty. Director Arthur Penn said of it: "Our goal was to show authentic violence, but at the same time the slowdown of time that a person experiences when watching something scary, like a car accident."

Slow motion reveals what is hidden from the human eye

Time-lapse video technology allows us to expand our natural visual abilities. It reveals data hidden in the “folds” of time, just as, for example, a microscope allows us to evaluate the structure of a cell or trace the life of microbes.

For example, subtle unconscious movements of the facial muscles that are so fast and brief that it is impossible to notice them with the naked eye. However, microexpressions can reveal a person who is lying. Neuroscientist David Eagleman cites the example of when child killer Susan Smith was caught on a news broadcast pleading for help in finding her child abductors, slow-motion footage showed facial expressions that could reveal her terrible lies.

Recently, scientists from Queen Mary University in London used time-lapse technology to study schizophrenia. Slow motion allowed us to explore non-verbal choreography in live interactions with patients at an unprecedented level of detail. In an experiment on subtle gestures, nods and body postures, researchers found that individuals with symptoms of schizophrenia were less engaged in dialogue and less likely to speak at the beginning of it, and they also had a harder time starting to communicate with their interlocutors.

Lie:

shifting gaze, slight smile, instant micro-tension of the facial muscles, dilation of the pupils, trembling of the lips, frequent blinking

Anger:

drooping eyebrows, tense lips and eyelids, wrinkled forehead

Disgust:

raised upper lip, squinted eyes, wrinkled nose and furrowed brows

Fear:

wide open eyes, parted mouth, raised eyebrows and flared nostrils

Happiness:

raised corners of the lips and cheeks, narrowed eyes, crow's feet on the outside of each eye

Astonishment:

lowered lower jaw, softened lips, widened eyes and slightly raised eyelids and eyebrows

Slow motion also helped explain the scientific paradox that “a bumblebee shouldn’t fly.” An insect with wings that are too small relative to the size and weight of its own body has long been of particular interest for research. A full study of the mechanics of bumblebee flight was limited by the capabilities of photographic equipment, which for a long time did not allow recording the exact trajectory of its wings. With the advent of sufficiently powerful video cameras, it was proven that the flight of insects does not violate physical laws. After analyzing video footage and supercomputer simulations of the complex movement of air around fast-moving wings, the myth was destroyed.

Slow motion as an expression of intimacy and romance

Slow motion video also allows you to capture the intimacy of a moment, whether it's the finish of a Tour de France race winner, a dance, or a guitar solo performed by your favorite musician. Live footage that reveals details that are invisible in real time, for example, drops of sweat flowing down the temples, facial expressions and body movements expressing emotions, involuntary gestures - all this gives the feeling that we know more about the person on the screen than he himself. This technique additionally creates a romantic aura, which is why it is so often used in love scenes in films and in lyrical music videos.

Wong Kar-wai, a recognized master who knows how to create a romantic atmosphere on the screen like no other, also actively uses the slow motion technique. One of the scenes of his film “In the Mood for Love” is especially expressive. To emphasize the love experiences that the main characters experience, before their fleeting meeting in a narrow staircase passage, they sadly wander around the frame for two minutes in slow motion.

Slow motion “tickles” the nervous system

Our consciousness loves to guess what will happen next. For example, when a ball is thrown into the air, our brains unconsciously begin to build patterns of its flight to predict where and when it will land. These patterns of behavior are so deeply ingrained in our nervous systems that if you toss a tennis ball in zero gravity (such as on board the ISS), you will still unconsciously reach out to catch it in the same way as if you tossed it in normal gravity. .

When watching a video in slow motion, the brain's expectations regarding the physics of what is happening do not correspond to what is seen on the screen. Imagine you're watching The Matrix and Trinity jumps up to kick an agent. Your brain makes an unconscious prediction about when it will land. But amazingly, time slows down, and Trinity hangs in the air longer than expected. As neuroscientists clarify, these inconsistencies keep our attention on what is happening and force us to focus as much as possible.
