How to Easily Speed Up a Video on iPhone - Best Tools and Methods

Suppose you want a long video to play faster. In such a case, learning how to speed up a video on an iPhone becomes important. From built-in features in iMovie to more complex options such as AVAide and CapCut, this guide shows many different ways of speeding up videos on your iPhone quickly and easily.

Part 1. Can You Speed Up a Video on iPhone

Yes, it is possible to speed up a video on iPhones. This option changes the relative speed of the playback so that the video is played faster than its original recording. So, these tools can make the video time-lapse or short clips faster, depending on how long it takes to go through them. Once you have saved the video, it will always come back in that resolution and allow you to share it in that resolution as well. It is rather straightforward and readily available, placing power in the hands of the user to change the pace of a video on an iPhone.

Part 2. The Best iPhone Video Speedup Method (More Than 2x)

If you are searching for a tool that can provide video speed well beyond the primary 2× limit, the AVAide Video Converter is perfect. This is an all-in-one solution that possesses powerful speed control features to manipulate video speed for creative purposes or shrink the size of the content. Using AVAide, videos can easily be accelerated to correlate with the duration required without compromising quality. Hence, this is an ideal option for users who want more than just the basic video speed changes.

Step 1Search for its official website and install AVAide Video Converter on your computer.

Step 2Launch the application, click the More Tools tab, then select Video Speed Controller from the tools provided by the application.

Step 3Next, click the + button to upload the video from your iPhone.

Step 4In the Video Speed Controller, pick from the buttons to set speed - it ranges from the slowest speed of 0.125× to the normal speed of 1× to 8× faster and ranges further up, allowing all speeds.

Step 5Finally, save your video by clicking the Export button – before that, review the preview video and make any necessary adjustments to the speed settings so the video meets your demands.

Part 3. How to Speed Up iPhone Video in iMovie

If you want to speed up or slow down a video, you do not need third-party applications because Apple provides an iMovie video editing app. With iMovie, you can slow down or speed up videos by 2 times, remove shake from video clips, cut, crop, and enhance visuals. This application supports several formats, such as MP4, Apple ProRes, AVCHD, and HEVC. Additionally, iMovie supports iCloud, allowing access across devices.

Step 1Open the application iMovie. You either open up an existing project or select Start New Project > Movie so that you can import a new video.

Step 2Move your video clip in a timeline and tap the speed icon, which looks like a speedometer. A yellow bar will appear above the clip.

Step 3By dragging the edges of the yellow bar, set a range for the extent to which speed can be altered. Alternatively, part of the clip can be tapped, and in the inspector, Add can be selected to set multiple speed ranges within the video.

Step 4At the bottom of the panel, move the speed slider anywhere between 0.125× (slow motion) and 2× (fast motion) as the situation demands adjusting the speed of the video.

Step 5When happy with all your adjustments, press Done to finalize the saving process. You can save the video in the iPhone gallery or share it with others.

Part 4. How to Fast Forward a Video on an iPhone

There are two ways to fast-forward videos on your iPhone. One uses CapCut, which allows fast speeds up to 100×, and the other uses the Photos application to edit and make simple adjustments to slow-motion videos. For faster edits of a slow-motion clip, use the Photos application; for more precision edits in video speed, use CapCut.

Method 1: How to Fast Forward a Video on iPhone via CapCut

CapCut is an all-around video editing software and iPhone application that enables users to increase the speed of videos up to 100 times the normal rate, making it perfect for very short clips. Additionally, as a versatile flip video app, CapCut allows users to rotate or mirror video clips easily, adding flexibility to their editing process.

Step 1Download CapCut on your iPhone. Create a new project or open an existing one containing the video you would like to fast forward.

Step 2Now tap on the video and select Edit on the bottom left. Then click on the Speed button.

Step 3Adjust Speed:

• Normal Speed: Allows changing the speed of the whole clip from 0.1 percent of normal to 100 percent of normal.

• Curve Speed: Making speed alterations requires choosing one of the symmetric configurations and providing a value between 0.1× and 10× within the range restriction.

Step 4Watch the video to see the modifications made. If satisfied, save the video.

Method 2: Speeding Up a Slow Motion Video In the iPhone Photos Application

If your video is enabled to be in slow motion, the Photos app can speed it up. This method, however, is limited to slow-motion videos only and cannot be used for normal footage videos.

Step 1Open your Photos app, locate the Albums tab and scroll down to SLO-MO videos.

Step 2Choose the video clip you wish to edit by tapping it and then select the Edit option.

Step 3Now, move the two white bars of time cop close to each other to shorten the slow-motion length.

Step 4Finally, press the Done button to save the changes made to speed settings.
