120 FPS Video Editing on iPhone: Add Slow Motion Anywhere with UpRes
Take Full Control of Slow Motion Editing
When you record on your iPhone, Apple forces you to choose between two camera modes — regular or slo-mo.
If you shoot in regular mode, you can’t add cinematic slow motion later.
And if you shoot in slo-mo, the entire video is slowed down — even the moments you want at normal speed.
This is a big limitation for creators who want control over timing, pacing, and storytelling.
Now, UpRes gives you a new option: save videos at 120 frames per second (fps) so you can add slow motion to any part of your video — not the whole thing.
Introducing the New 120 FPS Save Feature in UpRes
The latest update to UpRes introduces 120 FPS video saving, letting you shoot normally, then upgrade later.
No need to choose between Camera and Slo-Mo mode ever again.
Key Benefits
- 🎬 Add slow motion anywhere — highlight key moments like jumps, spins, or splashes.
- 🎥 Keep cinematic flow — combine real-time and slow-motion clips seamlessly.
- 💾 Save storage — shoot in standard 30 or 60 fps, then convert to 120 fps only when needed.
-
⚙️ Process locally — all conversions happen directly on your iPhone, keeping your files private.
With UpRes, you decide where the slow motion happens — and how much.
Why Not Just Record in 120 FPS on iPhone?
The new iPhone 17 Pro and some iPhone 16 models can record in 120 fps natively, but there’s a catch: huge file sizes.
Recording directly in 120 fps generates massive video files that quickly fill your storage, forcing you to delete or offload content.
UpRes latest release solves this problem.
You can record in standard resolution and convert to 120 fps later, creating smooth, cinematic slow motion without the storage bloat.
This makes UpRes the smarter, storage-efficient alternative for iPhone users who want pro-level control.
Compatible Devices
The new 120 FPS Save feature works on:
- iPhones running iOS 26 or later.
- iPhone 13 and newer models
All processing happens on-device, with no cloud uploads or subscriptions required.
Upgrade to the Smarter Way to Add Slow Motion
UpRes’s 120 FPS Save option is more than just a feature — it’s a new creative freedom.
You get to control your video’s speed, reduce storage waste, and enhance your storytelling — all from your iPhone.
