ReMaster: AI Video Upscaler

ReMaster — Bring Your Old Videos and Photos Back to Life

Turn blurry, low-resolution footage into sharp, vibrant memories. ReMaster uses on-device AI to upscale your videos and photos up to 4K and smooth out choppy motion — entirely on your iPhone or iPad, with nothing ever uploaded to the cloud.

Whether it's a clip from an old phone or a pixelated photo, ReMaster restores the detail that time and compression took away.

■ NEW: Memory Remaster
Remaster a lifetime of memories in one go. Choose a folder, and ReMaster finds every video and photo inside — including all its subfolders — and saves the results to a folder you pick, with exactly the same structure.
- Before you start, see how many files will be processed, how much space you need, and about how long it will take
- Your originals are never changed
- Files that can't be remastered — such as already high-resolution files, other formats, or documents — are copied as they are, so the new folder is complete. Their names are listed in a text file
- Stopped partway? Run it again with the same folders and it picks up where it left off
- On supported iPad models, processing continues in the background even when you switch apps or lock the screen. On other devices, the screen stays on while ReMaster works, and processing pauses when you leave the app and resumes when you return

■ Straight from your Photos library
Pick videos and photos right from your camera roll, and save the results back to your photo library. Folders in the Files app work too.

■ AI Super Resolution
Powered by Real-ESRGAN running entirely on-device, ReMaster reconstructs lost detail as it enlarges — up to 4x sharper, all the way to 4K. A faster Standard (Lanczos) mode is also available when you're in a hurry.

■ Smooth 60fps with AI Frame Interpolation
Turn 30fps video into silky-smooth 60fps. Advanced frame interpolation (RIFE) generates natural in-between frames so motion feels alive again.

■ Batch Processing
Select multiple items in the picker — or point ReMaster at a folder — and it remasters every video and photo, one after another.

■ Keeps What Matters
The shooting date, location, and camera details are carried over to remastered files, so they sit right next to the originals in your library.

■ Wide Format Support
- Video: MOV, MP4, and M4V
- Photos: JPEG and PNG (HEIC is converted automatically when you pick from Photos)
- Choose your output format (MP4 / MOV / JPEG / PNG)

■ Private by Design
Every pixel is processed locally using the Apple Neural Engine and GPU. Your videos and photos never leave your device — no account required.
