Plask Motion
Plask Motion turns an ordinary video into 3D character animation using AI motion capture, with no suits or sensors. Full-body and hand tracking, multi-person capture and FBX, GLB or BVH exports for animators, game developers and short-form creators.
What is Plask Motion?
Plask Motion is a browser-based AI motion capture and 3D animation tool published by Plask USA Inc. Its promise is stated plainly on the homepage: transform any video into professional 3D animation with AI motion capture, no suits or sensors required. An ordinary clip goes in, usable 3D motion data comes out.
The whole chain runs in the browser. You import a video, Plask extracts the motion, you apply it to a 3D model, stage the shot, then render or export. Capture covers the full body and the hands, handles several performers in a single clip, and supports eye blinking and physics for MMD and VRM models. Cinematography is assisted rather than manual: camera and lighting can be set automatically, and post-processing adds vignetting, motion blur, auto-focus depth of field and tone mapping. Animation leaves as FBX, GLB or BVH at a frame rate you choose, and nine integration guides cover Unreal Engine 4 and 5, iClone, After Effects, MetaHuman, VRoid, Blender, Cinema 4D and Ready Player Me, with Unity, Maya and 3ds Max also listed as compatible. Scenes can be shared, teams collaborate in real time, cloud storage runs from 1 GB to 10 GB depending on the plan, and a Community section lets users publish scenes.
The input rules are strict and worth reading first: mp4 or webm, 100 MB maximum, between 3 seconds and 5 minutes, 720p or better, horizontal, with the whole body in frame. Plask's software is designed to recognize only human forms, so animals and objects are out of scope. Multi-person clips add limits of their own: a fixed camera, no overlapping bodies, fewer than 10 people, under one minute and 1,800 frames.
Pricing is freemium: a permanent Free plan capped at 15 seconds of capture a day, Standard at USD 18 a month and Pro at USD 50 a month on a yearly commitment, both opening with a 7-day free trial. A separate Plask Shorts service has the team produce TikTok-style animations within 24 hours, quoted by form. The company is registered in the United States, with a mailing address care of a San Francisco law firm, but its roots are Korean and the interface ships in English, Korean and Japanese.

When to use Plask Motion / When not to
A quick filter to help you decide if Plask Motion is the right fit.
When to use Plask Motion
- 3D animators and indie studios working without access to a motion capture stage
- Game developers who need clean animation to drop into Unreal Engine or Unity
- Social media creators producing dance clips and other short-form vertical content
- Students and teachers, who qualify for a verified academic discount
- Anyone who needs fast previsualization: the Quick Start guide claims a first animation in about three minutes
When not to use Plask Motion
- Anyone capturing animals, vehicles or props: Plask's software is designed to recognize only human forms
- Editors with long or heavy source footage, since clips are capped at 5 minutes, 100 MB and mp4 or webm only
- Crowd work: multi-person capture stops at fewer than 10 people, one minute and 1,800 frames, on a fixed camera
- Developers who need an API or a mobile app, as neither is documented anywhere on the site
- Compliance-driven teams that require a signed DPA, a subprocessor list or SOC 2 / ISO 27001 certification, and productions that cannot grant an irrevocable promotional license over their footage
How to use Plask Motion
A typical end-to-end flow, from setup to results.
- Create an account and open the editor at motion.plask.ai from the Get Started or Login button
- Prepare the footage: horizontal, 720p or better, mp4 or webm, under 100 MB, between 3 seconds and 5 minutes
- Frame the performer full body and front-on, clearly separated from the background and in close-fitting clothes
- For multi-person clips, keep the camera fixed, avoid overlapping bodies and stay under 10 people, one minute and 1,800 frames
- Import the video from the Outliner's Import menu or the Add button under Assets, then click Generate
- Drag a 3D model from Assets onto the Canvas, or start from one of the default characters
- Drag the extracted animation onto the target bone of the model
- Play the scene and trim it with the From and To markers
- Select the bones, open the Export menu and pick the format, FBX, GLB or BVH, and the frame rate
- Check the exported file in your target software: 3ds Max, Maya, Unreal Engine, Unity or Blender

Data, GDPR & hosting
A consolidated view of how Plask Motion handles your data.
GDPR overview
Plask USA Inc. names itself Data Controller in its privacy policy, last updated 5 April 2023. For users in the EEA and the UK it states a legal basis, namely providing the service and making it usable, and lists rights of access, rectification, erasure or restriction, withdrawal of consent, portability, objection and complaint to a supervisory authority, with a ten-day response commitment and a portable copy within ten days. Cross-border transfer is explicit: personal information may be transferred to and processed in South Korea with the user's consent. Californian rights, Shine the Light and the CPRA, are handled separately. The gaps are just as clear: no Article 27 EU representative is designated, no Data Protection Officer is appointed, the contact being Privacy Officer Lee Junho, CEO, at support@plask.ai, and no DPA or subprocessor list is published.
Who owns the data?
Plask's Terms of Service state that users retain full ownership of their User IP, meaning the videos, models and animations they upload or create. That ownership comes with a broad grant, however: by using the service the user gives Plask USA Inc. an irrevocable, non-exclusive, fully-paid, royalty-free and worldwide license to access, review, use, copy, modify, create derivative works of, reproduce and analyze the content; to process it through machine learning, algorithmic optimization and human analysis; and to display and use it in advertising and promotion of Plask. Payment details are the exception: card data is handled by the payment processor, and the privacy policy states that Plask never receives or stores it.
Reuse rights
Because users keep ownership of their User IP, the animations and exported files can be reused, edited, sold or published without asking Plask for permission, subject to the Community Guidelines for anything shared publicly on the platform. On its own side, the privacy policy lists the purposes Plask pursues: delivering and personalizing the service, performing contracts, billing and collection, notifying users of changes, and marketing its own or third-party products, which can be switched off in the account profile. The data collected ranges from the user's image, likeness and performance to name, password, date of birth, phone number, place of residence, correspondence, transactions, search queries and crypto wallet address, alongside technical data such as IP address, device identifier and type, operating system, browser configuration and usage logs. Analytics are gathered through third-party services named as Google Analytics and HubSpot, with cookies and web beacons; behavioral tracking can be opted out of by emailing support@plask.ai. Data may be shared with subsidiaries and affiliates, contractually bound service providers, an acquirer in a merger or sale, marketing partners with consent, and authorities on lawful request. What the documents never settle is whether uploaded content is used to train models: the Terms license processing through machine learning without saying so, and no training opt-out is offered.
Data retention & training
Hosting summary
Plask's privacy policy names no hosting country, no data center and no cloud region. What it does say is that all information provided to the company is stored on secure servers behind firewalls, and that payment transactions are protected by SSL encryption. The only jurisdiction named anywhere is South Korea: users located outside the Republic of Korea are told that personal information may be transferred there and processed by Plask or its legally authorized information processors, with the user's consent. That clause, dated 5 April 2023, is a transfer and processing statement rather than a hosting declaration, so it should be read as an indication and not as a commitment. No hosting subprocessor is disclosed and no security certification such as SOC 2 or ISO 27001 is published. A technical observation made outside the policy, that the domain resolves to an Amazon anycast address and that site media is served from Supabase storage, is not a statement by the publisher and should not be treated as one. Organizations with data residency requirements should ask Plask directly before committing.

Things to keep in mind
Risks and trade-offs to weigh before adopting Plask Motion.
- The User IP license is irrevocable, worldwide and royalty-free, and expressly covers machine learning processing plus use of your footage in Plask's own advertising
- Nothing in the documents states whether uploaded content trains models, and no training opt-out exists: the only opt-outs cover behavioral tracking and promotional emails
- Personal data may be transferred to and processed in South Korea, under Korean retention rules that keep contract and payment records for up to five years
- The privacy policy lists your image, likeness and performance among the data collected, so think twice before uploading footage of minors, clients or colleagues without their agreement
- Automated capture invites over-reliance: output quality is bound to the source clip, and treating a generated take as final rather than as a draft to clean up will show in the work
- Thin compliance surface for business use, with no DPA, no subprocessor list, no SOC 2 or ISO 27001 certification, no Article 27 EU representative, and legal documents from 5 April 2023 that contradict themselves on jurisdiction
- Subscriptions renew automatically and amounts are non-refundable except where the law requires otherwise, while tight capture quotas create steady pressure to upgrade
Setup & Integrations
Technical difficulty
Low. Nothing is installed: everything runs in the browser at motion.plask.ai once an account is created. The documented path has five steps and the Quick Start guide claims a first animation in about three minutes, with default characters supplied so you do not need to own a 3D model. The real difficulty sits either side of the tool, in preparing a clip that meets the framing, angle, clothing and resolution rules, and in bringing the exported file into your 3D software. No rigging skill is needed for a first result, though handling bones and the Outliner assumes some 3D basics.

Should you pick Plask Motion?
Plask Motion sets out to democratize motion capture for creators who will never book a mocap stage, and on that measure it delivers. The full chain sits in one browser tab: a phone video goes in, motion is extracted, applied to a 3D model, staged with automatic camera and lighting, then rendered or exported as FBX, GLB or BVH for Unreal Engine, Unity, Blender or Maya. Hand tracking and multi-person capture are included even on the permanent Free plan, the documented five-step path gets you a first animation in minutes, and the academic discount makes it genuinely cheap for students and schools.
The reservations are real, though. Capture quotas are tight, at 15 seconds a day on Free and 10 minutes a month on Standard, so serious output means the Pro tier or careful rationing. Input rules are unforgiving: human forms only, horizontal video, 100 MB, five minutes. And the compliance surface is thin for anything beyond personal work, with no DPA, no subprocessor list, no security certification and no Article 27 EU representative, while the Terms grant Plask an irrevocable license to process your footage through machine learning and use it in its own promotion.
One signal deserves watching. The Terms and privacy policy are dated 5 April 2023 and still describe NFT and crypto wallet features that are nowhere in the product, the site copyright is frozen at 2024 and the changelog stops on 31 October 2024, even though the service is still online and answering.
The verdict: an excellent, low-friction way for indie animators, game developers, short-form creators and students to get usable motion data without hardware. Companies with data residency or procurement requirements, and anyone who cannot license their footage that broadly, should look elsewhere or ask Plask directly before committing.
