Why Change Video Speed?

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

To Get a Better Look

Slow down a video to show something that is difficult to see with the naked eye, like watching a replay in sports to see if a foot landed out of bounds, or to see someone dodging a bullet, Matrix-style.

To Speed Up Steps

If you make how-to videos, you may want to change video speed to shorten any extra-long steps. For instance, when making a cake, you can tell your viewers to grease and flour the pan, but you don’t need to show 3 minutes of you performing that task.

For Emphasis

When you slow down a video it can add visual interest or drama. Imagine a group of heroes walking slowly toward the camera on their way to defeat the bad guy, or a lifeguard shaking out her wet hair while a group of teen boys looks on.

For Humor

Speed up a video to add a comic, Charlie Chaplin-esque effect.

Easily Speed Up or Slow Down a Video on Any Device

Tips to Speed Up or Slow Down Videos

Here are some tips to change video speed with smooth, flawless speed effects.

Tip 1: Shoot for Slow Motion.

If you know before you shoot that you plan to slow down a 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 down a video in post, it won’t look as smooth.

Please note that when shooting at a higher frame rate, you need to add more lights. Shooting in low light can cause a flicker effect when you change video speed.

Tip 2: Ease In/Ease Out

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 a video. This will keep speed changes from being too abrupt for viewers.

Tip 3: Use 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 a video, and that you aren’t adding effects just because you can.
