How to Speed Up or Slow Down a Specific Part of a Video in CapCut

Editing videos has never been easier, thanks to CapCut. One of the most popular effects is changing the speed of your video — whether you want slow motion to emphasize a dramatic moment or fast motion to make your content more engaging. But what if you don’t want to change the speed of the entire clip?

In this guide, you’ll learn how to speed up or slow down a specific part of a video in CapCut, step by step, so you can create professional-looking edits for YouTube, TikTok, Instagram Reels, or any social media platform.



Why Adjust Video Speed?

Video speed control is more than just a fun effect. Here’s why it matters:

  • Highlight important actions in your video

  • Create cinematic slow-motion effects

  • Make your edits more dynamic and engaging

  • Improve pacing and storytelling

  • Increase viewer retention on short-form videos

By controlling only a section of your clip, you get full creative flexibility without affecting the entire video timeline.

Step-by-Step Tutorial: Change Speed of a Part of Video in CapCut

1. Import Your Video

Open CapCut and create a new project. Import the video clip you want to edit.

2. Identify the Part to Edit

Play your video and pause at the point where you want the speed change to start.

3. Split the Clip

Use the Split tool to cut the video at the starting point. Then split again at the end point of the section you want to adjust.

Now the section you want to speed up or slow down is isolated.

4. Adjust the Speed

Select the split section, tap Speed, and choose one of the following:

  • Normal → Simple speed increase or decrease

  • Curve → Smooth, advanced speed changes for a cinematic effect

Drag the speed slider to increase or decrease the playback speed.

5. Review and Fine-Tune

Play the video to ensure the speed adjustment looks natural. You can tweak it until the motion feels smooth and professional.

Tips for Better Video Speed Editing

  • Keep slow-motion above 0.5x to avoid choppy playback

  • Use Curve Speed for smooth transitions between normal, slow, and fast motion

  • Apply speed changes sparingly to keep your video natural

  • Sync speed changes with music or action for more engaging edits

Conclusion

CapCut makes it extremely easy to speed up or slow down specific parts of a video, allowing you to create professional edits without complicated software. With this simple technique, you can make your YouTube tutorials, Instagram Reels, and TikTok videos more engaging and dynamic.
