Frame 001What is it

What is AI rotoscoping?

Rotoscoping is isolating a subject from its background, frame by frame — the matte that lets you replace a backdrop, drop in an effect or cut a person out clean.

AI roto does it automatically. It’s auto rotoscoping that masks the subject in every frame of your video roto, so you skip the hand-drawn splines and the frame-by-frame tracing. Upload a clip, let the AI trace the edge, and pull back a cut-out or an alpha matte in the Pixazo editor. It’s the same idea as AI video background removal — here the focus is the matte and the mask itself. Every clip shown is illustrative, generated with Pixazo.

Frame 002The workflow

Rotoscope a video in three frames

No splines, no keyframes, no tracing — the whole roll runs in the browser.

FRAME 01

Upload your clip

Drop in the video with the subject you want to isolate — a person, a product, a car, an animal. Any ordinary background works.

FRAME 02

AI masks the subject

The model traces the subject’s edge and masks it in every frame automatically — the AI-roto alternative to drawing splines by hand.

FRAME 03

Export the cut-out

Pull back the subject cut out on transparency, or the alpha matte on its own, ready to composite onto a new background or effect.

Frame 003What you can do

One clip, every kind of mask

The same roto pass drives every deliverable — read it like a layer stack.

LAYERS06 ACTIVE
OBJECT
Mask an objectMask an object in a video — a phone, a sign, a car — to isolate it or hide it from the shot.
ISOLATE
Isolate a subjectIsolate a subject in a video from everything behind them, holding the edge through movement.
CUT-OUT
Cut out a subjectCut out a subject from a video and drop them onto a new background or a transparent export.
MASK
Video maskingAI video masking that follows the subject across the whole clip, no keyframing the mask by hand.
MATTE
Pull an alpha matteExport the alpha matte on its own for compositing — a built-in alpha matte generator, the roto deliverable done by AI.
PLATE
Clean plateRemove the masked subject entirely to leave a clean plate of the background behind them.
Frame 004Cut-outs

Subject in, matte out

Each of these was a full scene; AI roto isolated the subject and pulled the alpha matte off the background. All illustrative, generated with Pixazo.

Frame 005AI roto vs manual

Manual roto is billed by the frame

Traditional rotoscoping is slow, manual spline work — the reason studios and rotoscoping services price it per frame. AI roto does the first pass for you.

Frame 007Field notes

Get the cleanest matte

A few habits that help the edge hold — and the honest limits.

+

Contrast helps the edge. A subject that stands out from the background masks cleaner than one that blends into it.

+

Steady, well-lit footage wins. Even light and a stable shot give the AI a clearer edge to trace than a dark, noisy clip.

−

Fine hair and fast motion are hardest. Flyaway strands and motion blur can shimmer on tricky frames — check those before export.

−

It’s an AI first pass. For a broadcast-finished matte, studios still refine by hand — AI roto gets you most of the way, fast.

Frame 008FAQ

AI rotoscoping questions

What is AI rotoscoping?+
AI rotoscoping automatically masks and isolates a subject from its background in every frame of a video — the AI-roto alternative to drawing splines by hand. You get the subject cut out on transparency, or the alpha matte on its own.
How do I rotoscope a video?+
Upload your clip, let the AI mask the subject across the whole video, then export the cut-out or the matte. No keyframing, no manual tracing — it runs in your browser.
Can I mask an object or isolate a subject?+
Yes. AI video masking lets you mask an object, isolate a subject, or cut out a subject from a video — a person, a product, a car or an animal — and hold the edge as it moves. Whether you need to mask object in video, isolate subject in video, cut out subject from video, or rotoscope video end to end, it’s the same one-click flow.
Is AI roto as good as a rotoscoping company?+
AI roto does a fast, automatic first pass that covers most shots. For a broadcast-finished matte on a hard shot, rotoscoping services still refine by hand — but AI gets you most of the way in seconds, for free.
What footage works best?+
A steady, well-lit clip where the subject stands out from the background. High contrast and a stable shot give the cleanest mask; fine hair and fast motion are the hardest.
Is AI rotoscoping free?+
You can create while you build, and new accounts start with 100 credits. HD exports and premium models use credits.
