Smooth Slow Motion
Create smooth slow motion by interpolating new frames. Unlike simple speed reduction which duplicates frames, AI interpolation generates natural in-between frames for fluid slow-mo.

How to Use Smooth Slow Motion
- Upload your video file — MP4, MKV, MOV, and other formats are supported
- Choose the target frame rate — 24 FPS for film look, 60 FPS for smooth playback, 120/240 FPS for slow-motion
- Select Fast or Best Quality AI mode
- Click Process — processing time estimate shown before you start
- Download the smooth, high-FPS video
Features
- AI-generated intermediate frames for smooth slow motion
- No frame duplication — natural motion between keyframes
- Combine with speed reduction for ultra-smooth slow-mo
Frequently Asked Questions
- How do I convert a video to 60fps?
- Upload your video, choose 60 FPS as the target frame rate, and click Process. Our AI generates the in-between frames and returns a smooth 60fps video to download — no app or software to install.
- Can I convert 30fps to 60fps?
- Yes — that's the most popular use. Our AI doubles the frame rate from 30 to 60fps by painting a brand-new frame between every existing pair, which looks far smoother than simple frame-duplication.
- How does it make a video smoother?
- Our AI looks at how things move between two frames and paints brand-new frames in between — so playback looks fluid instead of choppy. It's smarter than simply duplicating frames, which only makes the file bigger, not smoother.
- Why is this tool popular for anime?
- Anime is typically animated at 24fps or lower. Boosting it to 60fps creates the silky-smooth look popular on YouTube anime edits — our AI handles anime particularly well since it was trained on diverse motion patterns.
- What can I do with 240 FPS?
- 240 FPS lets you create stunning slow-motion. Play back at 30fps for 8x slow-mo, or 60fps for 4x slow-mo. Perfect for sports highlights, dance videos, and cinematic moments.
- What's the difference between 120 and 240 FPS?
- 120 FPS is ideal for ultra-smooth playback on 120Hz displays (gaming monitors, newer phones). 240 FPS is for slow-motion — the extra frames give you more flexibility to slow down footage while keeping it buttery smooth.
- Will this increase file size?
- Yes, more frames means a larger file. A 4x FPS increase roughly quadruples the file size. You can use our Compress Video tool afterward to reduce file size while keeping the smooth motion.
