Speeding and slowing down the speed of a video is a marvel in the video editing world. In the older days, this feat was accomplished only by the big-budget filming industry.

This article will dive into how you can access the modern-day features available in video editing software. From these features, you can alter the speed of your video easily. However, before we get into the step-by-step guide, let's understand what fast and slow-mo videos are.

Part 1. What Are Fast and Slow Motion Videos?

As the name suggests, fast-motion videos are the ones that have been sped up from their average speed.

Similarly, slow-motion videos are the ones that have been slowed down from their average speed. The slow-motion effect, also known as the slow-mo effect, is widespread in modern cinema.

Now that we know what Fast and slow-motion videos are. Let's understand their applications. Or how you can use them in your videos. Scroll below to learn more!

Part 2. Why Should You Change the Speed of Your Videos?

The answer to this question would be that it's a personal creative decision that will allow you to make your videos more engaging.

Fast Motion Videos

Fast-motion videos are used in many areas of filming. For example, you can speed up your videos to create a funny video or shorten its length.

The fast-motion effect has many applications, such as cooking tutorial videos. For example, the step-by-step process of a cooking tutorial can be too long to fit into a single video. Or it could also help you in cases where you want to keep the length of the video short.

The fast motion of the steps will allow the viewer to quickly grasp the whole process without watching the entire video.

Slow Motion Videos

You can also slow down your videos to give the viewers a more detailed perspective of a scene. Or you can also create a slow-mo video that offers a general surreal vibe.

A famous example is in action films. The producers of the first Matrix film used the Slow-mo effect in the famous bullet dodging scene.

You may wonder how the film producers made the slow-mo effect. The technology at that time was less developed than the recent day. So, even you can create a slow-mo effect.

Before we get into the editing process, let's first understand what you will need to change the speed of your videos!

Part 3. What Will You Need to Change the Speed of Your Videos?

You will need the following essentials to change the speed of a video:

2. Video Clips

Well, it is evident that to change the speed of your videos, you will need video clips. But there are a few things you can keep in mind before adjusting the speed of a video.

Note: Slowing down a video requires a shot at a higher frame rate. The greater the frame rate, the better will be the slow-mo quality. On the other hand, speeding up videos does not have a strict frame rate requirement.

Part 4. How Can You Change the Speed of Your Videos?

Here you will learn two ways in which you can change the speed of your videos. The two methods to change the speed of your video are mentioned:

  • The speed adjustment panel.
  • Duration panel settings.

Let's get started with the editing process. The first method we will look into is the Speed Adjustment panel.

1. Change Speed With the Speed Adjustment Panel

The Speed Adjustment panel is the speed adjuster in the Wondershare Filmora software. This feature will give you a drag bar to adjust the speed of your video.

You can move the bar to the right to increase the speed of your video. Similarly, you can move it to the left to decrease the rate.

But before we use this feature, we will need to download the Filmora video editing software. So please scroll below to learn how to download it!

In the speed control panel, you can see the speed adjuster slider. A number will usually mark this at the end. This number tells you the current speed your video is calibrated in and how fast or slow the motion effects will be.

1.00 is always the average speed. 0.5 being half and 2.00 being double the average speed. To control the speed through the slider, you will need to do the following:

  • To increase the speed: Type in the number you want your rate to be. Or, drag the slider to the right as you wish.
  • To decrease the speed: Type in a number less than the standard 1.00, or you can drag the slider to the left as you wish.

The number of your speed can be an inconvenience if you have no prior experience. Instead, render the video and play it from the beginning with the changes that you made. It gives you a better idea of the speed of your video.

These were the methods by which you can change the speed of your video using the Speed Adjustment panel. Now let's move on to the following method to adjust the speed via the Duration panel.

2. Change Speed via the Duration Panel

The duration panel is one the most valuable features of Wondershare Filmora as it allows you to change the video speed by duration adjustment.

This feature is typically helpful when you have a space between video clips and want to fill it. By measuring the time between the two clips, you can adjust the duration of your video.

It will ultimately hasten the speed of your video. The hastening in rate will depend upon the gap. The smaller the gap, the faster the video will be. Similarly, the greater the gap is, the longer the video will be.

Apart from the Speed Adjustment Panel, the Duration Panel has the advantage of editing the speed of your video by simply typing in the text.

Step1 Import Video Clips to Timeline

After downloading Filmora, the next step is importing your video clips. To do so, follow the steps outlined below:

  • In the pop column, scroll below to Unifrom Speed.

It will open the uniform speed panel in the import window. Below the speed of the controls, you can notice The Duration Panel.

Slow Down The Video

To slow down the video clip, follow the steps mentioned below:

  • In The Duration Panel, Increase the time of the video.
  • Type in a number bigger than the normal value
Note: If the average speed of the video is 00:01:00:00, increasing the value of the duration to 00:02:00:00 will reduce the speed of your video by half.
