All in One AI Motion Analyzer
An advanced AI video player equipped with all the essential features you need to analyze your movement, including frame-by-frame playback, body part position tracking, and 3D simulation.
A function that allows you to frame-by-frame playback by pushing buttons. You can adjust the number of frames freely.
A function to play 2 videos next to each other. You can change the state from "Both videos" "Left Only" "Right Only"
A feature that allows you to move the video position vertically and horizontally, as well as zoom in and out. This is useful when comparing two videos or focusing on the movement of specific body parts.
A feature that combines the playback bars of two videos into a single control panel, allowing unified operations such as play, pause, and frame-by-frame navigation. Useful for comparing two movements side by side.
A feature that allows loop playback of only a specified section of the video. The loop range can be set from the settings panel.
You can play videos pre-configured by the administrator. This feature is useful for comparing user movements or testing system functionality.
FAQ
What can this system do?
This system is a next-generation AI analysis tool that not only includes traditional video player functions such as frame-by-frame playback and dual video display side by side, but also features advanced capabilities like AI-based motion analysis. It can visualize motion trajectories of a person in a video and recreate their movements as animations in 3D space.
It is suitable for a wide range of applications, including sports form checks, performance comparisons, and motion analysis for dance and fitness.
Is frame-by-frame playback available?
Yes, intuitive frame-by-frame playback is available by using the forward and backward buttons. While many video players offer this function on PC, our system also works seamlessly on smartphones, freeing users from the hassle of adjusting tiny progress bars. Additionally, you can customize the number of frames to skip, from 1 to 10 frames.
Can this system create 3D animations from videos?
No, this system is designed to reconstruct the positions of body parts in 3D space based on the person’s movements in the video. It does not generate visually elaborate, so-called“3D animations.”However, you can freely change the viewpoint within the 3D space and examine the reconstructed body positions from angles that were not visible before, allowing you to analyze your movements from new perspectives.
What features are available?

- 3D animation conversion: Reconstruct body movements in 3D space based on AI analysis.
- Pose estimation accuracy control: Adjust the accuracy level of AI-based pose estimation.
- Download feature: Export videos with overlaid trajectories and visual elements.
Do I need to download any software?
No. This system is a web-based application, and all features run directly in your browser. There is no need to install any software—simply access the system from your smartphone or PC to start using it.
What file formats are supported?
The system supports video file formats that are playable in your web browser. The upload section will automatically display the formats supported by your browser.
Is it available on mobile devices?
Yes, the system is compatible with smartphones and tablets. You can analyze recorded videos on the spot. However, to ensure stable performance and usability, certain features—such as dual playback and download—are available only on PC.
How accurate is the pose estimation?
The system utilizes a state-of-the-art pose estimation engine powered by AI to detect joint movements in real time. When the video is well-lit and the subject is clearly visible, it delivers highly accurate analysis. However, accuracy may decrease if the subject appears blurry or if the video is taken from low angles—such as placing the camera on the ground and shooting upward. In such cases, adjusting parameters through the AI's pose estimation accuracy tuning feature may help improve performance.
Is this system free to use?
Yes, all features—including video uploads, 3D analysis, and frame-by-frame playback—are currently available free of charge.
