How to Speed Up or Slow Down a Video for Free [Desktop, App & Online]

Whether you make How-to videos for YouTube, Independent films for festivals, or marketing films for businesses, your videos could benefit from a few speed effects. Reasons to slow down or speed up video vary from purely aesthetic to practical, but whatever your reasons, speed effects can add some serious production value to your projects. 

You may be thinking that cool fast motion and slow-mo effects are something for Hollywood-level editors and learning to do them right would take time. In reality it takes under a minute to slow down or speed up video, and the process couldn’t be easier. 

This article gives you a step-by-step guide on how to slow down or speed up video on your Windows or Mac device, how to perform other cool speed effects, and offers some tips and tricks for changing video speed.

Why Change Video Speed?

There are many reasons you may want to change the speed of your video, from creative and aesthetic reasons, to purely practical. 

A practical reason to slow down video would be to show something that could not be seen by the naked eye otherwise, like watching a replay in sports to see if a foot landed out of bounds. If you make how-to videos, you may want to speed up video of any extra long steps. For instance, when making a cake, you can tell your viewers to grease and flour the pan, but you dont need to show 3 minutes of you performing that task. 

Changing your video’s speed can also be a purely creative decision to add visual interest or drama.  If you slow down video, it can help emphasize a shot, while speeding up can add humor. If done correctly (and sparingly), these changes can also add production value to your videos.

Tips to Speed Up or Slow Down Videos

Here are some tips for adding smooth, flawless speed effects to your videos. 

Tip 1: Shoot for Slow Motion.

If you know before you shoot that you plan to slow down video in a shot, there are steps you can take to keep your effect from looking choppy. Change the frames per second so you are shooting at a higher speed (around 60fps will suffice for most slow-motion shots). If you shoot at regular speed and slow it down in post, it won’t look as smooth.  

Also, when shooting at a higher frame rate, you need to add more lights. Shooting in lowlight can cause a flicker effect. 

Tip 2:  Click the Ease In/Ease Out button. 

On most video editing software there will be Ease in and Ease Out (or Fade In and Fade Out) buttons you can select when you slow down or speed up video. This will keep speed changes from being too abrupt to viewers. 

Tip 3: Use Speed Effects Sparingly

While it’s true adding speed effects can add production value to your videos, adding too many can do the opposite. Make sure you have a reason to slow down or speed up video, and that you aren’t going crazy trying to add effects just because you can.

4. What is Video Speed?

Video speed is the rate at which video is captured per second. Most cameras capture nearly 30 frames per second (29.97 to be exact.) This was a legacy from broadcast frequency and video formats that differentiated around the globe.

When a video is captured at 30 frames per second (fps) or higher, you are capturing lots of micro-movement, creating detail. Therefore, you can get a fluid and smooth slow-motion video when slowed down.

5. What is Slow Motion?

If you aren't familiar with slow-motion or slo-mo, it's simply the effect in which time appears to be slowed down in a video. This is traditionally achieved by capturing frames faster than their playback speed. When replaying back at normal speed, time appears to be moving more slowly.

This can also be achieved when you slow down video to playback at a reduced speed. This is achieved in a video editing program that generates extra frames to create the effect of slowing down the action in the clip. This will make a clip's playback time longer.

In contrast, if you are trying to achieve the "cinematic movie look," you should be capturing at 24fps. This creates a slower capture. The human eye sees between 30-60fps meaning fewer frames give your footage a less realistic and more dramatic look.

6. What is a Time-Lapse?

Time-lapses aim to reduce the time during a video clip drastically. This is traditionally done by capturing frames much slower and playing them back faster. With time-lapse, video editing software will remove frames to create the effect of faster action in a clip.

As a result, it works exceptionally well for extremely long clips to make time go by quickly. For instance, using time-lapse to reduce a sunrise (or sunset) to a few seconds versus minutes can add a stimulating effect to your videos.
