How getting Premium works

  1. Pay $5 with PayPal (card or PayPal balance) — one time, never again.
  2. Your key appears right here after paying — this page shows it for 1 hour. It's also saved as AI-Upscale-Premium-Key.txt in your Downloads and printed in your PayPal receipt (as the item number).
  3. Open AI Upscale right away: it finds the key file by itself — or click Premium key → Enter key and paste it. Done, forever.

🛟 Contact me for troubleshooting: raiyanaukeli@gmail.com — paid but no key, payment problems, anything at all.

Once it's in the app, Premium is stored on your PC and survives updates and reinstalls — no subscription, no internet needed. Your key is personal: please don't share it (shared keys can be blocked). Lost it? Here's how to get it back.

Everything you need to know before downloading

💻 What you need

  • Windows 10 or 11 (64-bit)
  • NVIDIA GeForce RTX card — RTX 20, 30, 40 or 50 series (desktop or laptop)
  • 6 GB VRAM minimum, 8 GB+ ideal for 4K
  • NVIDIA driver 580 or newer (update in the NVIDIA App)
  • ~12 GB free disk space during install (~7 GB after)
  • Internet for the one-time install only

AMD / Intel graphics and Mac are not supported yet — the AI runs on NVIDIA's CUDA.

⚡ Install in 3 steps

  1. Extract the zip: right-click it → Extract All… → Extract. (It won't work from inside the zip.)
  2. Double-click 2 - INSTALL (double-click me) in the new folder and leave the window open until it says DONE (10–20 min, ~5 GB download).
  3. Done! AI Upscale opens by itself. Next time, open “AI Upscale” from your desktop.

See a blue “Windows protected your PC” box? That's normal for small apps — click More info → Run anyway.

The installer downloads a private copy of Python, PyTorch/TensorRT and the AI models from their official sources. Nothing is installed system-wide — delete the folder to uninstall.

🛡️ Safe & private

  • Your videos never leave your PC — everything runs locally
  • No account, no tracking. Premium has no ads at all
  • Scanned on VirusTotal by 60+ antivirus engines
  • Windows SmartScreen may say “unrecognized app” because it's new and unsigned — click More info → Run anyway

Made for everyone — especially low & mid-range GPUs

Great video tools shouldn't need a $2,000 graphics card or a monthly subscription. AI Upscale was built and tuned on an everyday RTX 5060 laptop, with lots of tricks (TensorRT, smart tiling, compiled models) so it runs fast on the kind of GPU most people actually have. The free edition stays free, and Premium is one small payment — never a subscription. 🙂

Features

Everything a pro video enhancer does — without the subscription. Premium marks what Premium adds.

🧠

Automatic content detection

Drop in a video and a small vision AI (CLIP) recognizes whether it's real footage, anime or 3D animation — then switches to the AI models made for that kind of video. No guessing which setting to pick.

🔎

Upscale to 1080p, 2K, 4K or your screen

State-of-the-art models (Real-ESRGAN, APISR, AnimeJaNai, Nomos2, …) rebuild real detail instead of just stretching pixels. Free: 1080p & 2K. Premium 4K and Screen above 2K.

🎞️

60 / 90 / 120 FPS interpolation Premium

RIFE 4.26 creates brand-new in-between frames for buttery-smooth motion, with scene-cut detection so cuts never smear.

🪄

Fix low-quality video

Old, blurry or blocky clips (480p, 720p, phone and messenger videos) get repair models plus extra cleanup — switched on automatically for very low-res files. It also spots “fake HD” files that were stretched from a lower resolution.

⚡

Speed / Balanced / Max detail

Three quality tiers, accelerated with NVIDIA TensorRT and compiled models — up to 3× faster than plain PyTorch, with identical output. Premium Max detail.

🎨

Live color grading

Brightness, contrast, gamma, saturation, vibrance, temperature, tint and hue — previewed live on the moving video. One-click looks: Vivid, Cinematic, Anime Pop, Warm, Cool, B&W.

🧽

Cleanup & detail

Temporal noise reduction, debanding for smooth gradients, adaptive sharpening and optional film grain.

👀

See it before you render

Before/after slider with zoom, “Compare looks” (Real vs Anime vs 3D side by side at your screen's real size), and a 10-second test render.

🐼

Meet Bao Premium

A little panda who waves hello, gets excited when you drag a video in, types away on his laptop while your video renders, naps when you pause and throws confetti when it's done.

📊

Live hardware monitor

GPU load, encoder, temperature, VRAM and power while rendering. Keeps your PC awake and pauses Wallpaper Engine during renders.

🎧

Pro-quality output

10-bit HEVC, AV1 or H.264 via NVENC, original audio kept, trim built in, MP4 or MKV (keeps subtitles).

🔒

100% local & private

No uploads, no cloud, no account. Your videos stay on your PC — it even works offline after installing.

How fast is it?

Measured on an RTX 5060 Laptop GPU (8 GB) — a 50-second clip upscaled to 2K at 120 FPS (Premium):

≈ 3 minSpeedgreat for quick jobs & previews
≈ 7 minBalancedthe sweet spot — recommended
≈ 55 minMax detailtransformer model, for final renders

Faster GPUs are proportionally faster. The first render with a new model takes an extra 1–3 minutes to optimise it for your GPU (once).

What people use AI Upscale for

An AI video upscaler and AI video enhancer for PC — here's what it's best at.

Upscale video to 4K

A video upscaler for PC that rebuilds real detail to enhance video quality — the low quality video fix for old clips, phone videos and soft “fake HD” files. An offline AI upscaler and NVIDIA RTX upscaler in one, with a free edition.

Anime upscaler

Upscale anime to 4K with clean lines and no smearing. This anime video upscaler uses APISR, AnimeJaNai and Real-ESRGAN — like a Real-ESRGAN GUI, but it picks the right model for you.

60 & 120 FPS converter

AI frame interpolation with RIFE interpolation (4.26) works as a 60fps converter and turns almost any clip into a smooth 120fps video. Increase video FPS without stutter or smeared scene cuts.

Topaz alternative, no subscription

Looking for a Topaz Video AI alternative? AI Upscale has a free AI upscaler edition and a $5 lifetime Premium — a video enhancer download with no subscription. It's also a great Wallpaper Engine upscale tool for live wallpapers.

FAQ

What's the difference between Free and Premium?

The free edition upscales clips under 1 minute to 1080p or 2K at the original frame rate with the Speed and Balanced models, and shows small ads. Premium removes every ad and unlocks videos of any length, 4K, 60/90/120 FPS, the Max detail models, a brand-new design and Bao the panda — plus all future updates.

Is Premium a subscription?

No — never. You pay $5 once and Premium is yours forever: no monthly fee, no renewals, no limitations, no expiry date. It even works offline — the app checks your key on your own PC, so it can't be switched off later.

What do I get when I pay?

A personal lifetime license key (it looks like AIU5-XXXXX-XXXXX-XXXXX-XXXXX) that unlocks: no ads, any video length, 4K, 60/90/120 FPS, Max detail, the Premium design with Bao the panda, and every future update. Plus a big thank-you from me. 💜

I paid — where is my key? / I lost my key

Your key is shown on this website for 1 hour right after paying (the 🔑 My Premium key button at the top shows it again during that time), it's saved to your Downloads as AI-Upscale-Premium-Key.txt, and it's printed in your PayPal receipt email as the item number. Can't find any of them? Email raiyanaukeli@gmail.com with your PayPal receipt and I'll send your key again — always.

Will I lose Premium if I update, reinstall or move the app?

No. The key is saved in two places on your PC (your Windows user folder and the app folder), so updates, reinstalls and moving the folder keep Premium. On a new PC, just enter the same key again. It never expires.

I paid but PayPal didn't bring me back here. What now?

No worries! Open this page again in the same browser — it will ask whether you finished paying and show your key. You'll also find the key in your PayPal receipt (item number). And if anything at all goes wrong, email me with your receipt and I'll sort it out.

I paid the optional $5 before Premium existed — do I get it?

Yes, of course! Thank you for being one of the first supporters. Email raiyanaukeli@gmail.com with your PayPal receipt and you'll get a lifetime Premium key.

Can I use the free edition forever?

Absolutely. 💜 It's free forever, with no trial timer. And if you can't afford Premium, that's completely okay — no hard feelings, ever. Sharing AI Upscale with a friend is a wonderful way to help too.

I paid but didn't get my key / payment trouble — who do I contact?

Contact me for troubleshooting: raiyanaukeli@gmail.com. Include your PayPal receipt (or the email you paid with) and I'll make sure you get your key.

Is the payment safe?

Yes. Payments go through PayPal's official, secure checkout (card or PayPal balance) — this website never sees your card or account details.

Can I use one key on more than one PC? Can I share it?

Use it on your own computers — that's fine. But please don't share your key: it's personal. Keys that get shared can be blocked in the next update, and then they stop working for everyone using them — including the person who bought them.

Is it safe? My antivirus or SmartScreen warned me.

The download is scanned by 60+ engines on VirusTotal (green button above). Because the installer is new and not code-signed, Windows SmartScreen may show “Windows protected your PC” — click More info → Run anyway. The installer only writes inside its own folder.

Do my videos get uploaded anywhere?

Never. Everything runs on your own GPU. After installing it works completely offline (the free edition needs the internet only to show its ads).

Which graphics cards work? What about AMD or Intel?

Any NVIDIA GeForce RTX card (20/30/40/50 series, desktop or laptop) with 6 GB+ VRAM. It was developed on an RTX 5060 Laptop GPU, so mid-range cards are first-class citizens. AMD, Intel and Mac aren't supported yet because the AI runs on NVIDIA CUDA.

Is this an alternative to paid upscalers like Topaz Video AI?

It's an independent tool that covers the same core jobs — AI upscaling, frame interpolation and enhancement — using well-known open models, for $0 or a one-time $5 instead of a subscription. Results depend on your video, so try the 10-second test and see for yourself.

What's the “automatic content detection”?

When you open a video, a small AI looks at a few frames and decides whether it's real footage, anime or 3D animation, then selects the matching upscaling models. You'll see a “Detected” badge, and you can always override it.

Can I make Wallpaper Engine wallpapers with it?

Yes — that's what it was made for! The Wallpaper preset (Premium) renders exactly at your screen's resolution at 120 FPS, and AI Upscale pauses Wallpaper Engine while rendering so your GPU is free.

Why is the first render slower?

The first time you use a model at a new video size, AI Upscale compiles it specifically for your GPU (1–3 minutes, shown as “Optimizing”). After that it's cached and starts instantly.

Where do the AI models come from?

From their original authors' official releases (Real-ESRGAN, APISR, AnimeJaNai, AniScale, Nomos2, RIFE, CLIP…), downloaded by the installer and checked with SHA-256. Some models are licensed for non-commercial use, so please use AI Upscale for personal projects. Full credits are in THIRD-PARTY-NOTICES.txt.

How do I update to a new version?

Download the new zip and extract it over your existing AI Upscale folder (replace the files). Your models, settings, history and Premium key are kept, and there's no need to install again.

How do I uninstall?

Delete the AI Upscale folder and its shortcuts. Nothing else is changed on your PC (your Premium key stays in %APPDATA%\AI Upscale in case you come back).

❤️ Keep it going for everyone ❤️

AI Upscale is made by one person. If it brought an old video back to life for you, Premium or a small donation (any amount, Free or Premium user) helps keep it alive and improving. Even just sharing it with a friend means a lot. Thank you! 🙏
