Questions
Good to know
How long does it take?
Processing time depends on the clip length, source resolution, frame rate, selected mode, and device. Test a short section on your own device before starting a long export. The app shows an estimate before you start; no universal processing-time benchmark is claimed.
Can I use my phone while it works?
Yes. Keep using other apps or lock your phone. Upscaling continues in the background with progress shown by iOS, and you'll get a notification when it's done.
Does it keep the sound?
Yes. The original audio is copied into the new video exactly as it was, so it stays in sync.
Are my videos uploaded?
No. Local Video Upscaler runs its AI model on your iPhone, iPad, or Mac. Videos are never uploaded, and there's no account.
What about HDR videos?
HDR videos are saved in standard dynamic range.
Is my original changed?
No. The app always saves a new copy.
How much does it cost?
$9.99 once in the U.S. App Store, checked November 10, 2026. No subscription or in-app purchases. Apple shows your local price before purchase.
What can it improve?
Soft, low-resolution footage and compression artifacts. It cannot recover heavy motion blur or out-of-focus detail. Output is capped at 4K; videos already at 4K are skipped. HDR exports use standard dynamic range. Your original is never changed.
Which devices are supported?
Available for iPhone with iOS 26.0 or later, iPad with iPadOS 26.0 or later, and Mac with macOS 26.0 or later. Universal purchase includes the approved iPhone, iPad, and Mac versions with one purchase. Using it on a Mac

Try one short clip before a long export
Use a copy of a short section with faces, movement, or fine texture. Compare the original and enhanced result at the same playback size. Extra pixels cannot recover every detail lost to blur or compression.
