The FaceReady glossary

Video calls have grown their own vocabulary, and a lot of it is fuzzier than it sounds. "Virtual camera", "beauty filter", "Touch Up My Appearance" — people use these as if they all mean the same thing, and they don't. Here's what each one actually means, with our honest take on where it helps and where it falls short.

Virtual camera

A virtual camera is software that sits between your real webcam and whatever app you're calling from. It takes the feed coming off your camera, does something to each frame, then presents itself to your computer as a camera you can pick — so in Zoom, Teams, Meet, Slack, Discord, OBS, FaceTime or Webex, "FaceReady" simply shows up in the camera list. You choose it the same way you'd choose your built-in camera.

That's the whole trick, and it's why a virtual camera works in every app instead of just one. It doesn't need the app to support anything special; it just needs the app to let you choose a camera, which they all do. If you're weighing up the options, see the alternatives roundup.

De-aging / live de-aging

De-aging is our idea of what a camera filter should actually do — take a few years off, live, while you talk. In practice that means softer jowls, covered greys, brighter and more rested eyes, and evened-out skin. The point isn't to turn you into someone else. It's the version of you on a good morning, after a proper night's sleep.

"Live" is the hard part: every frame has to be adjusted as your face moves, with no lag. And we draw a firm line — de-aging is not a face change. You stay unmistakably you, which is exactly why nobody on the call can tell it's on. If your reflection looks fine but the webcam doesn't, here's why the mirror and the camera disagree.

Beauty filter

"Beauty filter" is the catch-all term for any effect that's meant to make you look better on camera. Honestly, most of them don't do much beyond smoothing — they blur your skin into a smear, sometimes shrink your nose or widen your eyes, and the result reads as obviously filtered. That's the giveaway. The moment someone can see the filter, it's working against you.

We think the bar should be higher than "blur everything". A good adjustment is one nobody notices; a bad one announces itself. If you want the fuller picture of what's out there for work calls, we wrote about beauty filters for Zoom, Teams and Meet.

Skin smoothing / retouching

Skin smoothing is the single most common thing a filter does: it softens texture so pores, fine lines and blemishes fade. Retouching is the same idea borrowed from photo editing, where you'd painstakingly clean up a still image. On a live call, the software has to do that to every frame as it goes.

Done gently, it just looks like good lighting. Pushed too hard, you get that waxy, plastic look where skin loses all its detail and your face starts to look flat. Less is nearly always better here: a touch of smoothing reads as "well rested"; a lot of it reads as "filter on".

Touch Up My Appearance

Touch Up My Appearance is Zoom's built-in skin smoother. You'll find it under Settings → Video as a slider. It softens your skin a little, and that's genuinely useful for a quick polish before a meeting.

The catch is it only does the one thing — mild smoothing — and only inside Zoom. Switch to Teams or Meet and it's gone, because it's a Zoom feature rather than a camera. It also can't help with greys, tired eyes or the way a webcam flattens your face. We pulled apart where it runs out of road in why Zoom's Touch Up isn't enough.

Snap Camera

Snap Camera was a free desktop app from Snap Inc., the company behind Snapchat. It launched in 2018 and let you pipe Snapchat-style lenses — the dog ears, the potato, the more subtle face tweaks — into desktop apps like Zoom. For a while it was how a lot of people first discovered virtual cameras at all.

Snap discontinued it in January 2023, and the desktop app stopped working. That left a real gap, because plenty of people had quietly come to rely on it. We covered the shutdown and what to do about it in what happened to Snap Camera.

Webcam filter

"Webcam filter" is the everyday phrase for any effect applied to your camera before it reaches a call — beauty filters, background blur, colour tweaks, lenses, the lot. It's a description of what someone wants ("I want a filter on my webcam") more than a specific piece of software.

The thing worth knowing is how the filter gets there. App-specific filters live inside one app and vanish when you switch. A filter delivered through a virtual camera follows you into every app, because it's the camera itself doing the work. That difference is usually what people are actually asking about when they say "webcam filter".

Neural Engine / on-device AI

The Neural Engine is the dedicated chip Apple builds into its silicon for running AI work fast and efficiently, right there on the Mac. "On-device AI" just means the processing happens on your machine rather than on someone's server.

For a camera, that's the whole privacy story in a sentence. FaceReady runs every frame on-device, on your own machine — nothing is uploaded, there's no cloud round-trip, no account, and nothing is stored. Your face never leaves your computer. On-device isn't just faster; it's the reason we can promise that what the camera sees stays with you.

The "Zoom boom"

"Zoom boom" is the shorthand for what happened when video calls became the default way to meet. Suddenly we were all spending hours a day looking at our own faces in a little window — something almost nobody did before — and a lot of people noticed they were paying far more attention to how they looked on screen.

There's nothing mysterious about it. Stare at any small, slightly distorted picture of yourself for long enough and you start picking at the details. That self-consciousness is the itch a good camera filter is meant to settle, so you can get back to the actual conversation instead of watching yourself have it.

Frame rate & latency

Frame rate is how many images a camera produces each second, measured in fps. Most webcams run at 30fps, and that's the number a live filter has to keep up with — every single frame needs adjusting before it goes out, thirty times a second. Latency is the lag between something happening in front of the camera and it showing up on the call.

This is why "live" is harder than it sounds. If the software can't process frames fast enough, you get dropped frames, stutter, or your face lagging behind your voice — and any of those is far more distracting than a few greys ever were. A de-aging camera lives or dies on staying fast: keep the frame rate steady and the latency invisible, and it just looks like you, only better.
