Speed ramping — the technique of gradually changing video speed within a single clip — is used in Hollywood blockbusters and viral social media videos alike. The good news? You can achieve this effect right from your phone.
What Is Speed Ramping?
Speed ramping involves smoothly transitioning between different playback speeds within a single clip. Unlike a hard cut from normal to slow motion, speed ramping creates a fluid, cinematic feel that guides the viewer's attention.
When to Use Speed Ramping
- Action sequences: Slow down the peak moment, then speed back up
- Dance videos: Emphasize key moves with slow motion
- Product reveals: Build anticipation with normal speed, then slow down the reveal
- Sports content: Highlight the critical moment of impact or skill
How to Speed Ramp with EvoMotion
EvoMotion makes speed ramping intuitive. Import your clip, then use the speed curve editor to set keyframes. Drag the curve down for slow motion (0.1x–0.5x) and up for fast motion (2x–10x). The app automatically smooths the transitions between speeds.
Pro Tips
- Shoot at 60fps or higher for smoother slow-motion segments
- Time your speed changes to match the beat of your music
- Keep slow-motion segments short for maximum impact
- Use fast motion for travel and transition sections
