How to Slow Down a Video on iPhone Using the Photos App
Want to know how to slow down a video on your iPhone using its built-in features?
The Photos app offers a quick way to adjust videos already shot in Slo-Mo mode.
Here’s how:
- Step 1: Open the Photos app on your iPhone.
- Step 2: Find and tap the video you want to edit. This method works best if the video was originally recorded in your iPhone's Slo-Mo camera mode.
- Step 3: Tap "Edit" in the top-right corner.
- Step 4: Look at the video timeline at the bottom. If your video has Slo-Mo sections, you'll see denser vertical lines indicating these parts. Drag the handles (the taller white lines) to adjust where the slow-motion effect begins and ends. The section between the handles will play in slow motion, while the parts outside will play at normal speed.
- Step 5: Happy with your changes? Tap "Done" to save your slow-motion video.
Important Note: If your video was not originally recorded in your iPhone's Slo-Mo mode, you cannot add a new slow-motion effect directly using only the Photos app. For these regular videos, or if you want more precise control, you’ll need a dedicated video editing app. An excellent choice is YouCam Video, which lets you easily make any video slow motion on your iPhone, regardless of how it was shot.

Can I make an iPhone video slow motion *after* I've recorded it?
Yes, absolutely! This is a common question. While the iPhone's built-in Photos app primarily adjusts videos already shot in Slo-Mo mode, you can easily make any existing video slow motion on your iPhone after recording using third-party apps. Apps like YouCam Video, iMovie, CapCut, or InShot are designed for this. Simply import your normally recorded video into the app and use their speed adjustment tools to create the slow-motion effect.
How to slow down a video on iPhone without an app, if it wasn't shot in Slo-Mo?
Unfortunately, if your video wasn't originally recorded using your iPhone's Slo-Mo camera setting, the built-in Photos app doesn't allow you to add a new slow-motion effect to it. The Photos app can only adjust the slow-motion portions of videos that were *already* captured in Slo-Mo. To slow down a regular video on your iPhone, you'll need to use a video editing app like iMovie (which is free from Apple) or other popular choices like YouCam Video.
What's the best app to make videos slow motion on iPhone in 2025?
There are many great apps in 2025! Some top choices to make your iPhone videos slow motion include:
- YouCam Video: Highly recommended for its ease of use, precise speed controls, and additional features like video quality enhancement, making it ideal to slow down video on iPhone smoothly.
- iMovie: A solid free option from Apple, good for basic speed adjustments.
- CapCut: Very popular for social media, offering robust speed tools and other trendy effects.
- InShot: A user-friendly editor with good speed control features.
- Slow Fast Slow: Specifically designed for intuitive speed ramp effects.
The "best" app often depends on your specific needs and how much control you want over the editing process.
How can I slow down an iPhone video without making it look choppy or blurry?
To get smooth slow motion on your iPhone videos in 2025, follow these tips:
- Record at a Higher Frame Rate: If possible, shoot your original video at a higher frame rate (e.g., 60 FPS, 120 FPS, or even 240 FPS if your iPhone supports it for Slo-Mo). More frames per second mean smoother slow motion when you slow the video down.
- Use Quality Editing Apps: Apps like YouCam Video often use advanced algorithms (sometimes called frame blending or optical flow) to create smoother transitions between frames when slowing down footage.
- Don't Overdo It: The more you slow down a video (especially one shot at a standard frame rate like 30 FPS), the higher the chance of it looking choppy. Experiment to find the sweet spot.
- Enhance if Needed: Some apps, including YouCam Video, offer video enhancement tools that can help improve clarity if slowing down introduces slight blurriness.
Does slowing down an iPhone video reduce its quality?
Slowing down a video can sometimes affect its perceived quality, but it's not always a straightforward "reduction." Here's why:
- Choppiness: If the original video has a low frame rate (e.g., 24 or 30 FPS) and you slow it down significantly, each frame is displayed for a longer time. This can make the motion appear less fluid or "choppy." This is the most common quality concern.
- Blurriness: Extreme slowing might reveal motion blur that was less noticeable at normal speed or if the editing app uses frame interpolation that isn't perfect.
- File Size: Ironically, slowing a video down doesn't usually decrease file size much, and if advanced processing is used, it might even increase slightly.
However, using a good video editing app like YouCam Video, especially with footage shot at higher frame rates, can help minimize these effects and maintain good visual quality for your slow-motion iPhone videos.
