Video Speed Control Options
Change your video playback speed to create different effects:
- Slow Motion (0.25x - 0.75x): Perfect for sports analysis, tutorials, or dramatic effects
- Normal Speed (1x): Original video speed
- Fast Motion (1.25x - 2x): Speed up slow content or create energetic effects
- Time-Lapse (2.5x - 4x): Compress long videos into shorter clips
Common Use Cases
- Sports Analysis: Slow down gameplay to analyze techniques
- Tutorials: Slow motion for detailed demonstrations
- Time-Lapse: Speed up long processes (painting, construction, cooking)
- Social Media: Create engaging sped-up or slow-motion content
- Presentations: Speed up lengthy footage
