Why not generate at 4K?
Cloud upscalers need the upload before they can start, then charge per minute. For footage under NDA or a security policy, the upload is the blocker. Acuta removes it: the work runs on hardware you already own.
How it works
- Choose the clip
Read from your disk. Any aspect ratio, at least 720 pixels on the short edge, up to 10 minutes.
- Check three frames
Model beside plain upscale, at actual pixels, before anything renders.
- Export to your disk
There is no server in the chain.
Questions
- What does this site send?
- One short hardware report, after a notice with a Don’t send button, and an email only if you type one. The privacy page lists every field. The extension sends no hardware report.
- Can security review it?
- Yes. The privacy page is written for that reader. Enterprise plans add source review.
- How long does it take?
- A 30-second export takes at least 2½ minutes on an M3 Max, plugged in, a floor, not a promise. Plug in: on battery, Apple silicon runs roughly an order of magnitude slower.
- How good is it?
- It slightly over-sharpens the mid-tones on video, by 8–10%. That was measured, never resolved, and not investigated, and it can read as a synthetic crispness on skin and on gradients when you look closely on a big display. Nobody has run a review of logos and small type, so check your own in the preview before you sign off.
