To speed up a video on your iPhone, you have several options depending on the type of video and the level of speed adjustment you want:

1. Using the Photos App (Best for Slo-Mo Videos)

• Open the Photos app and find the video you want to speed up.
• Tap Edit in the top right corner.
• If it's a slo-mo video, you'll see vertical white bars beneath the timeline. Drag these bars closer together to remove the slow-motion effect and speed up the video.
• Tap Done to save your changes.

This method is primarily for speeding up slo-mo videos by removing the slow- motion effect

2. Using iMovie (For Regular Videos)

• Open the iMovie app on your iPhone.
• Tap the + button and select Movie.
• Import the video you want to speed up and tap Create Movie.
• Tap the video clip in the timeline to select it.
• Tap the Speed button (speedometer icon) at the bottom.
• Drag the speed slider to the right to increase the speed, up to 2x the original speed.
• Tap Done and then share or save your sped-up video.

iMovie allows you to speed up regular videos up to 2x and also adjust audio speed to match

3. Using Third-Party Apps (For More Speed and Flexibility)

If you want to speed up videos beyond 2x or have more control, apps like CapCut , Videoshop , or FilmoraGo can help:

• Download and open the app.
• Import your video.
• Use the speed adjustment feature to increase the speed (some apps allow up to 100x).
• Export and save the edited video.

CapCut, for example, is popular for its ease of use and advanced speed controls
