To speed up a video on an iPhone, the most straightforward methods are using the Photos app or the iMovie app. In the Photos app, open the video, tap Edit, then use the speed slider to increase the speed and tap Done to save the change. However, this method works best for time-lapse or slo-mo videos with limited speed adjustments. For more flexible speed control, especially for regular videos, use the iMovie app: create a new movie project, import the video, tap the clip in the timeline, tap the speedometer icon, drag the slider to the right to speed up (up to 2x), and save. If needing speeds beyond 2x, re-importing the exported video into iMovie multiple times or using third- party apps like CapCut or Video Candy can achieve faster speeds up to 100x or more. Summary of the main steps:
Method| Steps| Max Speed
---|---|---
Photos App| Open video > Edit > Speed slider > Drag right > Done| Limited,
best for time-lapse/slo-mo
iMovie App| New project > Import video > Tap clip > Speed button > Drag right
Done| 2x
iMovie Repeat| Export then re-import and speed up again| Multiple of 2x
Third-party Apps| Use apps like CapCut for advanced speed control| Up to 100x or more
This provides a clear way to speed up iPhone videos using built-in and third- party tools.
