Accelerated videos and Slow-Motion are becoming mainstream lately. 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? This question was asked by my nephew last weekend. Unfortunately my old model Samsung did not manage to create a 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 thing to start learning about slow-motion is the frame rate. It is measured in fps - the number of frames per second. Modern smartphones can offer 120 fps, the iPhone 6 has taken the bar at 240 fps. How much do we need for slow motion? The average frequency of videos that we watch on TV or on the network is 24 frames per second. It is at this speed that our brain stops defining frames as separate incoherent pictures and perceives them as movement.

How do I shoot a half-motion slow motion video at 24 frames per second? It's very simple, you need a camera with a frame rate of at least 48 fps. But the video slowed down by 2 times is not quite slow-motion yet: the majority of users tend to get 5-10 times slowing down. Accordingly, the required frame rate is increased. Therefore, offers of amateur cameras with a frequency of 1000 fps or more appear on the market.

For slow motion shooting you need a "high-speed" camera and a slow shutter speed

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

But it will not do without pitfalls: the lower the shutter speed, the less light falls on the matrix. Hence the conclusion: you can shoot at a frequency of 120fps either in bright natural light or using lighting devices.

How to spot a fake slow-motion effect

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

In addition, the main advantage of slow-motion is in the details that elude our view in life and in ordinary 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 to decorate a Youtube channel, you need at least several thousand fps.

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

Time scale

Time scale- a quantitative measure of motion deceleration, equal to the ratio of the projection frame rate to the shooting frame rate. So, if the projected frame rate is 24 frames per second, and filming was performed at 72 frames per second, the time scale is 1: 3.

The maximum degree of acceleration is determined by the design of the camera, the dynamic characteristics of the jump mechanism of the camera. In amateur equipment, accelerated shooting at frequencies up to 64-72 frames per second is provided. Professional equipment uses specialized grapple mechanisms that provide 360 ​​frames per second for 35 mm film and 600 frames per second for 16 mm.

Increasing the speed above these values ​​is carried out by changing the method of fixing a frame on film.

High-speed filming

High-speed filming(rapid shooting, from fr. rapide- fast) - filming with a frame rate of 200 to 10,000 frames per second. It is carried out with continuous uniform motion of film using various optical and electronic ways switching the luminous flux.

It is used in various fields of science and technology to study short-term and fast-running processes. Such are, for example, the processes of combustion and explosion, the interaction of various mechanisms, the propagation of shock waves and spark discharges.

It is used to create popular science and educational films that demonstrate in detail all phases of the movement of the subject.

The main ways to implement high-speed filming:

Optical compensation

In order for the image of the frame to remain stationary relative to the uniformly moving film, a rotating prism or mirror is introduced. The size and position of this optical element are chosen such that the linear displacement of the resulting image corresponds to the movement of the film.

Short-term exposure

With this method, slotted shutters cut off short times for the exposure of each frame.

Another common method is to use pulsed light sources with a flash rate that matches the required frame rate. However, for this, the duration of the flashes must be extremely short, about 10 −7 seconds.

High speed filming

High speed filming(Ultra-rapid shooting) - filming with a frame rate from 10 4 to 10 9 frames per second. Film in this method of shooting remains stationary during exposure, and the beams of light generated by the optical system that form the image move. Usually, a rotating mirror prism is used for this.

Optical switching

The film is placed on the surface of the cylinder in a special film channel. A commutation prism and a secondary lens are usually placed opposite each future frame. A mirror rotates in the center of the cylinder, which performs "sweeping" along the length of the film. This method it is used for processes taking place in a relatively small volume. The direction of the axis of the high-speed camera is unchanged.

Electronic switching

With this method, an object moving along a row of fixed lenses located along the fixed film is illuminated by separate light sources. This method is most often used for fast moving objects.

Frameless Image Dissection

Frameless shooting using raster systems

Photochronography (slit frameless shooting)

Application

In cinema, television and computer games is used to repeat and show interesting points in detail, especially in sports.

In feature films, the use of accelerated filming creates the impression of reduced gravity when simulating human movement in the lunar and Martian landscapes. Also, accelerated shooting is used in model shooting to create the illusion of a collapse or destruction of a large object at a great distance from the camera (for example, part of the shooting in the film "The Crew" was performed).

TOP 15 programs for Slow Mo

Slow mo - or "Slow motion"- is a kind of time dilation effect.

It should be noted that this effect is very popular, as a result of which it is quite often used in professional cinematography.

Obtaining the desired result is achieved, oddly enough, due to a completely opposite action - increasing the speed of the captured scene.

Subsequently, this video is played back at the usual rate - 24 frames per second - and get beautiful slow-motion scenes.

However, for such shooting, filmmakers use special expensive cameras that allow high-speed shooting.

Due to the high cost, such equipment is available only to a few, therefore, for a huge amateur army, they began to create all kinds of editors that allow simulating the effect of slowing down.

Slow motion is a time dilation effect that has been widely used in the film industry lately. How is slow motion video filmed? Interestingly, the visual slowdown of the video is achieved through accelerated shooting - with a frequency of up to 10,000 frames per second. In this shooting mode, the camera lens manages to “see” in detail and in small things what is imperceptible to the human eye. When the footage shot in this way is played back at a typical rate of 24 frames per second, there is a feeling of time slowing down.

Basically, special high-speed video cameras are used to create the slow motion effect. The problem is that not every video amateur can afford such expensive professional equipment. What if you still want to create an interesting and stylish video using the slow motion effect?

We offer you a simple solution: try Movavi Video Editor! It's not only great program for slow motion, but also a multifunctional editor that allows you to quickly and easily edit full-length movies. You only need to download the program, load the footage into it, and you can slow down any fragment of the video right on your computer with just a couple of keystrokes. Download Video Editor right now and follow our instructions.

1. Install Movavi Video Editor

Run the file you downloaded and follow the installation instructions.

2. Add video to the program

Run the program and select Create a project in advanced mode... Then press the button Add files in the tab Import and select a video to edit. The files you selected will be automatically added to the workspace at the bottom of the program window.

3 (Optional). Cut out the desired fragment

If you want to effectively slow down a specific section of your video, you need to first cut it from the general footage. To do this, put a red marker at the beginning of the selected fragment and press the button Cut... Then put a marker at the end of the fragment and press again Cut... Now you can apply the slow motion effect specifically to this section of the video.

4. Apply a slow motion effect

Double click on the video you want to slow down. The tab will open Instruments... Find the option Slow motion... Move the slider Speed to set the desired deceleration rate.

5 (Optional). Remove audio from video and add soundtrack

Let's say you're editing a "slowmotion" video about snowboarding downhill. To create the desired viewing experience for the viewer, it will not be superfluous to add some suitable music. But do not forget that the audio track of the video you slowed down also slowed down, which may sound strange in your movie. The easiest way out of the situation is to lower the video volume to zero and then overlay another audio track on top of it.

To do this, click on the icon Mute the entire track as shown in the illustration. Now go to the tab Import, press the button Add files and load the desired audio file into the program (as you did at the very beginning with video files). It will be automatically added to Audio track under your video. More detailed information about adding music to video can be found in our
