CapCut has rapidly become one of the most popular mobile video editing apps thanks to its powerful features, intuitive interface, and free access. Among its many tools, the slow motion effect is a fan favorite — used to enhance cinematic storytelling, highlight important moments, and boost engagement across platforms like TikTok, Instagram Reels, and YouTube Shorts. In this in-depth guide, you’ll learn exactly how to add slow motion in CapCut, the difference between normal and curve speed, pro tips for best results, and how to avoid common beginner mistakes.
What is Slow Motion and Why Use It?
Slow motion is a video editing effect that reduces the playback speed of a video clip, making motion appear slower than normal. This effect can be used for a variety of creative and practical reasons:
-
Emphasize key moments (e.g., action scenes, expressions, movement)
-
Create dramatic, emotional impact
-
Increase viewer retention and engagement
-
Help the audience focus on important visual details
CapCut makes it incredibly easy to apply this effect in just a few steps, whether you’re a complete beginner or an experienced content creator.
How to Add Slow Motion in CapCut: Step-by-Step Tutorial
Download and Open CapCut
If you haven’t already, download CapCut from the Google Play Store or the Apple App Store. Once installed, open the app and tap on “New Project” to get started.
Import Your Video
Choose the video clip from your phone’s gallery that you want to edit. CapCut will load the video into the editing timeline.
Trim or Split the Video (Optional)
If you want to apply the slow motion effect to only a portion of the clip, use the “Split” tool to divide the video into segments.
-
Tap the video in the timeline.
-
Move the playhead to the point where you want to cut.
-
Tap “Split” — now you can work on just the desired section.
Apply Slow Motion Using the “Speed” Tool
CapCut offers two main options for changing speed:
Option 1: Normal Speed
-
Select the clip you want to edit.
-
Tap “Speed” > “Normal”.
-
Drag the speed slider left to slow down (e.g., 0.5x, 0.3x).
-
Tap the checkmark to apply.
Best for beginners and straightforward slow motion without transitions.
Option 2: Curve Speed (Advanced Slow Motion)
-
Tap “Speed” > “Curve”.
-
Choose a preset (like “Hero”, “Bullet”, or “Jump Cut”) or tap “Custom”.
-
Add keyframes and adjust speed curves manually to create dynamic slow-fast transitions.
Best for cinematic or creative edits, where motion changes over time.
Preview and Adjust
Hit the Play button to preview your this feature effect. If it looks choppy or unnatural, try adjusting the speed or use a clip recorded at a higher frame rate (more on that below).
Optional: Enhance Your Slow Motion Clips
To take your slow motion edits to the next level, try adding these creative touches:
1. Add Music or Sound Effects
this feature works great with dramatic music or synchronized sound effects. CapCut offers a wide library of free audio under the “Audio” tab.
2. Apply Filters and Color Grading
Use the “Filters” or “Adjust” panel to give your clip a specific mood — vintage, cinematic, cool, or warm.
3. Insert Transitions or Zoom
Combine this feature with a zoom-in or cinematic transition for a professional look.
4. Add Text or Subtitles
Highlight dialogue or create emotion with well-timed titles or subtitles during your slow-mo moments.
Best Practices for Smooth Slow Motion in CapCut
Not all slow motion is created equal. Here’s how to get the smoothest, highest-quality results:
Record at High Frame Rates
For buttery-smooth this feature, shoot your original footage at 60fps, 120fps, or even 240fps if supported by your phone. The higher the frame rate, the smoother the slow-down will appear.
Use Curve Speed for Better Transitions
The Curve Speed option allows you to control speed at multiple points, letting you ramp down and ramp back up gradually instead of an abrupt change.
Avoid Slowing Down Low-FPS Clips
If your video was recorded at 30fps or lower, slowing it down too much can result in choppy or blurry playback.
Use Motion Blur (if available)
CapCut sometimes offers a Motion Blur effect to smoothen frames. Use this for fast-moving scenes that are slowed down.
Common Mistakes to Avoid
-
❌ Overusing this feature: Use it sparingly for best impact.
-
❌ Using this feature on shaky footage: Stabilize clips first for better results.
-
❌ Slowing down low-quality videos: It can ruin video clarity and smoothness.
-
❌ Ignoring audio: this feature may distort sound — mute it or replace it with music.
Exporting Your Video
Once you’re done editing:
-
Tap the Export icon in the top-right corner.
-
Choose your resolution (1080p is standard).
-
Select the frame rate (30fps or 60fps).
-
Tap Export and wait for it to save to your gallery.
You can now upload your masterpiece directly to TikTok, Instagram, YouTube, or anywhere else!
