How to Convert Slow Motion Video to Normal Speed on iPhone and Computer

iPhone has begun to support slo-mo video since iPhone 5s iOS 9. From the new iPhone 15 experiment shot released by Apple, we can see this mobile's mature and stunning slo-mo skills on water, sound and light. Slo-mo, full name slow motion, also abbreviated as slo-mo, was originally taken by a highly specialized camera and used in pro-level movies, TVs, events, or natural showings to present an artistic effect. But today, with the continuous hardware upgrades, even generally inexpensive phones are capable of capturing high-fps slo-mo video, opening up a new funny world for personal videography.

How to Convert Slow Motion Video to Normal Speed on iPhone

This is the easiest and most direct way to normalize the speed of iPhone slo-mo video. Please follow the steps below.

Step 1. Access to Photos app and navigate to the slo-mo video you'd like to watch at normal speed.

Step 2. Tap the video and click "Edit" located in the top right area to have speed controls shown up right below the video.

Step 3. There are quite many vertical lines or say tick marks above speed control. After watching the video completely, you will see the video part with more spaced out vertical lines has a slow motion effect and the other sections with tight tick marks have regular speed. Therefore, when you want to leave all video content at normal speed, you only need to move either of the timeline handles to the other, the leftmost slider to the right end or vice versa to remove the slow motion effect.

Step 4. Tap "Done" to apply the operation. Next time you watch the video, you will enjoy a regular-speed video.

How to Convert Slow Motion Video to Normal Speed on Computer

Instead of controlling the playback mode with fps and duration unchanged, you are suggested to maintain the slow-motion effect by slowing down video with a video editor, for instance, lowering video fps from 240 to 30 with the duration from 4s to 32s.

Now we set an easy instruction with VideoProc Vlogger, a totally free and slick iPhone video editor, to slow down iPhone high fps slo-mo video permanently.

As a fully-featured iPhone video editor, VideoProc Vlogger not only supports changing the linear speed, but also supports adjusting no-linear speed (speed ramping). Besides, VideoProc Vlogger allows you to add motion effects, edit background music, color grade and color correct your footage for more stunning effects.

Step 1. Free download VideoProc Vlogger on a Windows or macOS computer, and then finish the installation to launch.

Step 2. Export iPhone slo-mo video to the hard drive via Photos/AutoPlay app on Windows or Photos app on Mac. If you have no idea how to do it, read this official guide.

Step 3. Import iPhone slo-mo video into VideoProc Vlogger by clicking the big + icon on the main interface. Then drag and drop it to the Video Track in the Timeline.

Step 4. Browse the Inspector Panel on the right side of the Preview Window and find the Play Speed menu. Choose from the linear speed listed, or click the custom button to enter the play speed from 0.3 (32x slower) to 32 (32x faster). You can also change the speed of the video by setting its duration.

Step 5. Click "OK" to save the speed change. Continue to do other editing or hit Export to output real slo-motion video at hardware-accelerated speed.

Pro Tips: Enhance the Video with AI Frame Interpolation

Simply changing a slow-mo video to normal speed might cause frame drops and make it look jittery. Fortunately, VideoProc Converter AI, a handy companion to VideoProc Vlogger, can generate natural and realistic frames in between and deliver smoother footage. With the AI Neuronet Trained models, its FPS interpolation tool can study consecutive frames, estimate pixel behaviors, and process footage with complex motion intelligently.

VideoProc Converter AI offers quick editing, converting, compressing, downloading, and recording services. And currently, it takes a big stride in AI video processing. On top of FPS interpolation, it's set to upgrading with cutting-edge AI upscaling and stabilization features.

Now download and install VideoProc Converter AI to enhance the video quality with advanced AI frame interpolation!

Step 1. Launch VideoProc Converte AI and choose the "Frame Interpolation" feature in its main UI.

Step 2. Drag and drop the video you just converted to normal speed to it.

Step 3. Set the FPS to 2X or 3X. If there are big scene changes in your footage, enable the "Skip scene changes" option to avoid artifacts in transitions.

Step 4. Choose an output format and export.

Note: The Windows version now supports AI-powered Super Resolution, Frame Interpolation, and Stabilization to enhance video and image quality. These AI features are not yet available in the Mac version but will be coming soon.

How to Copy Slow-mo Video off iPhone for Normally Playback

Slo-mo is a limited feature of Apple. Put it in simple words, Apple only empowers Camera and Photos apps on iOS to "slow down" a portion of 120/240fps video and display at 30fps.

Therefore, you can only keep the slow motion effect in Camera, and Photos apps or through default Share sheet to upload to YouTube, Facebook, Vimeo, etc. When exporting or syncing the original slo-mo to a computer, sending it to other non-iOS devices (via chatting apps or text message), or uploading it to cloud services or sites, not via Share sheet, the video will play at the natural high frame rate, no slow motion anymore.

List of Slo-Mo Shooting iPhones & Available Options

Apple first introduced slo-mo shooting to the iPhone in Sept. 2013 and then started to support speed control in the iPhone 6 lineup. Through years of hardware updates and performance improvements, it's able to shoot 1080p HD at up to 240fps slo-mo effortlessly. Whenever you want to produce amazing slo-mo with iPhone, you simply need to:

-> 1. Open up the native Camera app from the Home page.

-> 2. Swipe twice to the right to navigate to Slo-Mo mode.

-> 3. Press the record button to begin the shooting.

-> 4. Press the red button to stop recording and enjoy slo-mo at once.

Note that most iPhone selects the lower resolution and frame rate combination by default to capture relatively smaller slo-mo video. If you prefer higher resolution or fps, e.g. from 720p to 1080p or 120fps to 240fps, you can reset it in "Settings -> Camera -> Record Slo-mo". To preserve the camera settings, please turn the Camera Mode switch on under Settings -> Camera.

In this way, you can easily make award-winning slo-mo videos of any action scenes or natural phenomena around you, and share them on social sites with proper edits or not. Slow motion is cool, but how to change the slow-motion video to normal speed? Here this guide will share 2 easy ways to help you realize it, along with more related information on iPhone slow motion.
