How AI video enhancers actually work
There are hundreds of "AI video enhancer" websites. Most run the same handful of underlying models — and some are thin wrappers that quietly forward your footage to a third-party API. Here's what's really under the hood, and why it matters for your privacy.
The same models power most tools
Two open-source models do most of the heavy lifting across the industry:
- Real-ESRGAN — the go-to model for AI upscaling and detail recovery.
- GFPGAN — restores faces, sharpening eyes and features in portraits and old film.
Because these are freely available, a large share of online enhancers are built on top of them. That's why so many tools produce broadly similar results — they're often running the same engine with a different interface on top.
Three kinds of "AI video enhancer"
1. API resellers
A website that forwards your upload to a third-party API (e.g. a model-hosting service) and shows you the result. Fast to build — but your video passes through a company you never chose.
2. Desktop apps
Software you install that runs models on your own GPU (Topaz, AVCLabs, HitPaw). Private, but needs hardware, installation, and usually a license.
3. Self-run cloud
A service that runs the models on its own infrastructure. You get online convenience without your file bouncing through extra third parties. This is where BetterVideo sits.
Why the "wrapper" question matters for privacy
If a tool is a thin wrapper, your footage may be sent to — and temporarily stored by — an API provider you were never told about. For a meme clip, who cares. For family archives, client work, or sensitive footage, every extra hop is extra risk.
Where BetterVideo differs: we run Real-ESRGAN and GFPGAN (plus contrast and sharpening) on our own GPU infrastructure — your video isn't resold to a third-party enhancement API. We don't train on your uploads, and files auto-delete. Same proven models, without the mystery middlemen.
What to ask before you upload
- Does this tool run the models itself, or forward my file to another API?
- Is my video used to train AI?
- How long is it retained, and can it be deleted?
- Where is it processed?

Frequently asked questions
Do AI video enhancers use the same models?
Many do — Real-ESRGAN and GFPGAN are open-source and power a large share of online enhancers, which is why results across tools often look similar.
What's wrong with a tool reselling an API?
Nothing inherently — but your video passes through an extra company you didn't choose, adding privacy and retention risk. It matters most for sensitive footage.
Does BetterVideo resell a third-party API?
No. BetterVideo runs its models on its own infrastructure, doesn't train on uploads, and auto-deletes files.
