How to speed up a video on iPhone using iMovie?
Time needed: 5 minutes
The easiest way to speed up a video is to use iMovie on iPhone. Follow these steps:
- First, open iMovie on your iPhone and start a new project. If you already have a project, open it and move to step three.
- Those starting a new project. Select Movie and the next screen will allow you to choose what media to add to the project. Select any clips to add to the project.
- Now, tap one of the clips within your timeline to reveal the inspector.
- You can then select the speed button at the bottom of the screen. Click the speed button and then adjust the slider to change the speed of your clip.
- Additionally, you can create ranges within a clip. This allows you to make a specific part fast. There are two methods to create a range: either drag the yellow range handles to create a start and end to your clip, or you can select Add within the inspector to create another range.
- If you want to create more ranges, simply select an area of the clip that is outside of your current range. You can also tap Add from the inspector, allowing you to create a new range from the border of the playhead position. You can view what ranges you have via the vertical white lines at the bottom of a clip.
- Tap anywhere outside of the inspector to dismiss it when you are finished. Remember that if you want the audio to change with your speed, you’ll need to tap the gear icon (settings) and select Speed changes pitch (it should be on by default).
Note that you can search the Apple App Store for other video editors, but I prefer this one because it is the most accessible.
NOTE
Tips
- Instead of applying one speed to the whole clip, create ranges to speed up only specific parts.
- If you want the audio to match the speed change, make sure “Speed changes pitch” is enabled in iMovie settings.
- Start with small videos before editing long ones. It makes learning easier.
- Speeding up plus trimming gives you tighter, more engaging videos.
- Always save the final video in the highest resolution available to avoid quality loss.
