How to Change Video Speed Online?
Changing the speed of your videos can create dramatic effects, from smooth slow-motion highlights to fast-paced time-lapse sequences. Our free online video speed changer makes it easy to adjust video playback rates without installing any software. Here's how it works and why you might want to use it.
Benefits of Changing Video Speed
Slow Motion Effects
- Highlight important moments in sports videos
- Create dramatic effects in action sequences
- Analyze movement in educational content
- Add artistic flair to music videos
Speed Up Effects
- Create time-lapse videos of long processes
- Condense long presentations or tutorials
- Show progression over time (clouds, construction, etc.)
- Create comedic fast-motion scenes
Understanding Speed Settings
- 0.25x - 0.5x: Slow motion effects - good for detailed movement analysis or dramatic moments
- 1x: Normal playback speed
- 1.5x - 2x: Slightly accelerated - useful for fast-forwarding through less important content
- 4x: Time-lapse effect - ideal for showing processes that take a long time
Audio Options Explained
When changing video speed, you have two main audio options:
- Preserve Audio: Keep the audio track in your video. Disable this for purely visual time-lapse videos.
- Preserve Audio Pitch: When enabled, voices and music will maintain their normal pitch even at different speeds. When disabled:
- Slow motion videos will have deeper, slower voices
- Sped-up videos will have higher-pitched "chipmunk" voices
Pro Tip: For best results when creating slow-motion videos, use footage that was recorded at a high frame rate (60fps or higher). This ensures smooth playback even at very slow speeds.
