AI Motion Capture: 10 Markerless Tools Compared

For AI motion capture without a suit, Move.ai gets studios closest to optical data using iPhones. Rokoko Vision, DeepMotion and Krikey AI are the easy free ways to turn a phone video into 3D animation, Plask Motion handles several people in one clip, RADiCAL captures live from a webcam, and Wonder Dynamics (Flow Studio) also drops the CG character into your real footage.

Markerless motion capture uses AI to pull 3D movement out of plain video. That can be a phone clip, a webcam or a few cameras. The performer wears no markers and no sensor suit. It has moved mocap from a six-figure studio job to something an indie developer can do with a tripod and a laptop.

There is a catch. Markerless capture can't match a real optical or suit rig on fine precision. Results also depend on light, on how much of the body is hidden, and on the footage. But for previs, indie games, social content and lots of pro work, that trade is fine. The ten tools below are the ones worth a look.

Comparison table

Studio and entry-level capture

1. Move.ai

Move.ai is for studios that want data good enough to replace an optical marker system. Its multi-camera mode uses two to six iPhones on tripods. The company says the result is on par with an inertial suit, or with a full optical rig when all six cameras are used. Its Dex tech adds hand and finger tracking from normal video. It can also track more than 20 people at once across a space as big as a stadium. Few markerless tools aim that high.

Best for: studios and big productions that want optical-quality data without renting an optical stage. All you need is phones.

Where it falls short: it still trails true optical markers on the hardest shots. It struggles when the body is hidden or the clothes are very loose. Paying per second, per camera, adds up fast on long sessions.

Pricing: pay as you go from $0.012/second (one camera, Gen 1) up to $0.043/second per camera for multi-camera Gen 2. A 30-day Move Pro trial costs $995.

2. Rokoko Vision

Rokoko Vision is the free, no-hardware way into Rokoko. The same company sells mocap suits and gloves that cost thousands of dollars. So Vision is built as a first step with a clear upgrade path, not as a rival on pure quality. It takes video from a webcam, phone or DSLR and processes it in the cloud. The suits are still the better pick once a project needs more than a camera can give.

Best for: creators who want a free start and may move up to Rokoko's suits and gloves later.

Where it falls short: free single-camera capture only takes short clips. The more precise two-camera mode needs a paid Plus or Pro plan.

Pricing: free Starter plan with unlimited FBX exports. Paid Plus and Pro plans add two-camera capture, BVH/CSV export and live streaming.

3. DeepMotion (Animate 3D)

DeepMotion's Animate 3D does one thing. You upload a video of a person moving. Its AI tracks the movement and uses it to rig and animate a 3D character. No suit, no markers and no special training. The team includes people from Blizzard, Pixar, Disney and Ubisoft. The tool also adds physics on top of the tracked motion, so a character moves with real weight instead of floating.

Best for: indie developers and animators who want the simplest path from a phone video to a usable 3D animation.

Where it falls short: results depend a lot on how clear the footage is. It is built mainly for human characters, not creatures or other non-human rigs.

Pricing: plans start at $9/month, and a free-forever tier lets you test it.

4. Plask Motion

Plask runs in the browser and can track up to five people in one video. It captures the full body, hands and face. It also has cleanup tools built in, like foot locking and motion smoothing. Most rivals leave that work to a separate 3D app. Its free tier gives 900 credits a day, which is enough for real commercial work, not just tests.

Best for: creators who need several people in a shot and want to clean up the motion in the same tool instead of in Blender.

Where it falls short: everything runs on credits, even on paid plans. Tracking several people uses far more credits than tracking one.

Pricing: Standard plan from $18/month (billed annually). A free tier covers one-person capture.

Browser, budget, and keyframe tools

5. RADiCAL

RADiCAL's big feature is live capture. You don't upload a video and wait. A performer streams from a webcam and sees the 3D animation as it happens. You can stream the result into Blender, Unreal, Unity or Maya. RADiCAL Canvas adds a 3D scene builder in the browser. You can block, light and frame a scene around the take without leaving the page.

Best for: previs and virtual production, where seeing the motion right away changes how you direct the shoot.

Where it falls short: it does well with one person. Busy scenes with several people or tricky interactions often need manual cleanup. The free tier is capped by hours of use per year.

Pricing: free Personal plan with up to 24 hours of use per year. Professional plan from $20/month (or about $8/month billed annually).

6. QuickMagic

QuickMagic covers more than body motion. It does half-body, full-body, face and hand tracking. All of it draws from one credit pool that it shares with its avatar tools. That makes it a handy one-stop pick. It handles one person or several, and it exports to FBX, Mixamo, BIP and Unreal Engine.

Best for: creators on a tight budget who want face and hand capture without paying for a second tool.

Where it falls short: the free tier gives 50 credits a month and caps clips at 30 seconds. That is tight for more than quick tests. Mocap and avatar features also share the same credits.

Pricing: free plan with 50 credits a month. Starter plan from $9.90/month.

7. Cascadeur

Cascadeur is the odd one out on this list. It doesn't capture motion from video at all. It is a keyframe animation app that uses AI to make hand animation much faster. With AutoPosing and its physics engine, an animator sets a key pose and the follow-through motion fills in on its own. It skips the suit in a different way: hand animation gets fast enough to compete with capture.

Best for: animators doing physics-heavy action, like fights, falls and acrobatics, where filming a real performer would be risky or hard.

Where it falls short: it's a keyframing tool with its own learning curve. If you need to pull a real performance out of video, it won't do that.

Pricing: free indie license for non-commercial use. Paid plans start around $8 to $12/month, and Pro and Teams tiers run $25 to $49/month.

8. Krikey AI

Krikey is about getting a finished result fast, not about top capture quality. You upload a video, and its AI Video to Animation tool turns it into a 3D animation. You don't need rigging or animation skills. It targets game developers, filmmakers and marketing teams who want results in minutes, not days. Teams that need a set style can get a custom AI model through its enterprise services.

Best for: creators with no animation background who want a simple path from video to avatar.

Where it falls short: it puts ease and speed first. It lacks the fine cleanup and precision controls of tools built only for mocap.

Pricing: free-forever plan. Pro plan from $15/month with unlimited credits and 4K exports.

Production compositing and retargeting

9. Wonder Dynamics (Flow Studio)

The tool once called Wonder Dynamics is now part of Autodesk's Flow Studio. It captures body, hand and face motion from live-action footage shot on any camera. Then it goes further than most. It animates and lights a CG character and composites it into the original shot. It supports custom rigs and auto-retargeting. It exports to Maya, Blender, Unreal, 3ds Max and USD. That makes it a real production tool, not a quick-capture app.

Best for: productions that want mocap and VFX character work done in one place, instead of exporting the data and compositing it elsewhere.

Where it falls short: it's built for producing whole shots, and its credits are priced for that. If you just need clean motion data from a simple take, it's more than you need.

Pricing: free tier with 300 starting credits. Paid plans run from $45/month (Lite) to $95/month (Pro).

10. Viggle PINOC

PINOC runs on JST, Viggle's own video-to-3D model. Its main strength is a physics-aware solve that respects weight, contact and timing. It outputs a 65-bone skeleton with Mixamo names, so it drops onto a rigged character with no manual remapping. A text-to-motion mode makes 3D animation from a written prompt. That helps with background motion nobody has time to animate or act out.

Best for: creators who want the quickest path from a captured or described motion to a character moving in their scene, with no remapping step.

Where it falls short: paid credits work out to roughly $2 to $2.60 per minute of mocap. Reviewers say that is pricey next to some rivals once the free welcome credits run out.

Pricing: free to start with welcome credits. Paid use from roughly $2 per minute of motion on the Pro tier.

After capture: invideo agent (not mocap)

invideo agent is not a motion capture tool. It's an AI video generator and editor, so it isn't counted in the ten above. It comes in after capture. Once a mocap tool has made an animated character, invideo agent is where that take becomes a finished, edited video that stays consistent across several scenes.

It uses the same persistent context engine as invideo agent's other consistency features. Once you lock a character's look, it carries over to every shot, scene and session in a project. That matters as soon as a mocap character shows up in more than one scene. Camera Controls let you add a set camera move around the take, like a dolly-in, an orbit or a crash zoom. The platform also sends each shot to the best fit of its 200+ models, including Veo 3.1, Sora 2, Kling 3.0, Seedance 2.0, Recraft and GPT Image 2.0. So a mocap character can sit next to fully AI-made shots in the same project with no visible seam.

Best for: creators who already have a character performance from one of the mocap tools above and need it edited into a finished video with several scenes.

Where it falls short: it can't capture anything itself. It only helps once you have motion data or an animated character.

Pricing: plans start at $17/month, with team and enterprise options too.
