Changing video speed is arguably a must-have procedure when editing. Maybe you need to speed up a video clip to convey time passage or skip less important/repeated parts of a video. Or maybe you need to slow down a video that was shot at an inconsistent frame rate unintentionally to match your delivery requirements.

However, some of you might be thinking that changing video speed during editing can be a difficult beast. I hear your concern, but don't worry. This article will show you step-by-step tutorials to speed up or slow down a video easily.

How to Speed Up or Slow Down Videos in VSDC

Platform: Windows

Pricing: Free; Pro version at $19.99

VSDC has a free version, but it's almost the same as the pro version. It possesses lots of editing features like altering the speed of a video, applying video/audio effects, adding shapes, extracting/adding audio tracks, inserting subtitles, etc., which satisfies me greatly. Only problem is that it uses a confusing operation philosophy that is different from other video editors. Anyway, altering the video's speed in VSDC is extremely simple. The steps below will walk you through how to create gradual speed up/down effects in VSDC.

Step 1. Create a new project with needed video settings.

Step 2. Import footage to the timeline. Then separate it to fragments using Split into parts hidden in the Editor on the top.

Step 3. Select the clip in the timeline and set a required rate in the Properties windows.

Step 4. Set a higher or lower speed rate to achieve gradual alternation effects.

How to Speed Up or Slow Down Videos in iMovie

Platform: macOS

Pricing: Free

iMovie is a must-have video editor for Apple users. It perfectly works and produces nice results when it comes to speed alternation. There are two ways to change clip speed in iMovie: the speed pop-up menu and the speed editor. The first one gives you full controls of clip speed, including custom speed adjustments, fast and slow modes, free frame, reverse and preserve pitch. The speed editor allows you to alter clip speed directly in the timeline. Moving the speed slider to left accelerates a clip with a shorter duration; moving the speed slider to right slows a clip with a longer duration.

To make videos fast/slow using the speed pop-up menu.

Step 1. Open iMovie and create a new project > import video clips > add clips to the timeline.

Step 2. Split the clips into parts so that you can alter parts of the clip speed.

Step 3. Make a selection to the clip you would make speed adjustments > head over to the menus above the viewer > Select Speed.
