How to Fast Forward a Video on iPhone Up to 8× Easily

Want to make a long iPhone video shorter or create a quick-motion effect? You can fast forward a video on iPhone using Apple's built-in tools first. For regular videos, iMovie is a good video speed controller. It lets you increase a clip's speed up to 2× and can apply different speeds to different sections of the same video. If 2× is not fast enough, you can move the video to a Mac or Windows PC and use 4Easysoft Total Video Converter. It supports speeding up a video from 0.125× to 8×, along with output settings for format, resolution, and frame rate.

How Fast Can You Make a Video on iPhone

With iMovie on iPhone, you can speed up a video to 2× its original speed. You can also slow down a video to as little as 1/8×.

For a lot of clips, 2× video speed does the job. But it starts to feel limiting when you're trying to turn a long recording into something short and watchable.

Take a 30-minute video, for example:

• At 2×, that's about 15 minutes.
• At 4×, that's roughly 7.5 minutes.
• At 8×, you're down to around 3 minutes and 45 seconds.

If you plan to adjust the video speed to 4×, 8×, or a custom speed, iMovie won't let you do that. A desktop video speed changer gives you a lot more room to put a video in fast-forward than your iPhone allows.

Can You Fast Forward a Video in the iPhone Photos App

It depends on the type of video you're working with.

The Photos app only lets you adjust speed on certain slow-motion recordings. The little slider lets you drag the "fast" section wider or narrower. It's not built to speed up a regular video. If you try to find a speed option on a normal clip, you won't see one. Because the Photos app doesn't have it.

Step 1Open the Photos app. Select your Slo-Mo clip.

Step 2Tap the "Edit" button in the top-right corner.

Step 3You'll see a bar under the video with two white lines. This marks the slow-motion section.

Step 4Drag the white lines closer together to reduce the slow-motion effect (or move them off the clip entirely to remove it).

Step 5Or you can tap the "Speedometer" button in the top-right corner and then select the playback speed from the drop-down menu.

Step 6Tap the "Done" button to change the video speed.

How to Fast Forward a Video on iPhone with iMovie

You can change the speed of the entire clip or only certain sections with the iMovie app. This is useful when you want to shorten a long recording without removing any footage. The process only takes a few taps, although iMovie has a 2× speed limit. Here is how to speed up your video on iPhone using iMovie step by step.

Step 1Open iMovie on your iPhone. Create a new movie project or open an existing one.

Step 2Add the video you want to speed up to the timeline, then tap the clip to bring up its editing controls.

Step 3Tap the "Speed" button with the "Speedometer" icon at the bottom of the screen. A speed slider will pop up.

Step 4Drag the slider to the right to make your video play faster. Or you can use the range handles to select just the section you want to speed up. It is supported to add multiple ranges with different ranges.

Step 5Tap the "Done" and "Share" buttons to fast forward an existing video at 2× on iPhone, then export it.

How to Fast Forward an iPhone Video More Than 2×

iMovie on iPhone stops at 2×, which can be limiting for long recordings or time-lapse-style clips. 4Easysoft Total Video Converter provides a Video Speed Controller that supports speeds from 0.125× to 8×. So, you're not stuck at iMovie's ceiling. It also lets you preview the change before you commit to exporting, which matters once you're not just fast-forwarding through a video but actually creating and saving a new file at that speed.

Step 1Open 4Easysoft Total Video Converter. Go to the "Toolbox" section.

Step 2Find and click the "Video Speed Controller" button. Add your video. Choose the video playback speed up to 8×. Click the "Export" button to confirm and change the video speed.

Step 3Go back to the main interface. Select your output format from the "Convert All to" drop-down menu. Moreover, you can click the "Settings" button to adjust the video resolution, bitrate, and more. Click the "Convert All" button to get a new video with the selected playback speed.

What Happens to the Audio When You Fast Forward a Video

Fast-forwarding a video also makes its audio play faster. In iMovie, the pitch is typically kept constant when you change the video speed. If you want the pitch to rise or fall with the speed, turn on the "Speed changes pitch" option in the project settings. At higher speeds, the original audio can become hard to understand. For tutorials, lectures, and long recordings, it may be better to mute the original audio and add background music or a new voice track instead.
