AI Action Recognition姿态分析Video PlaybackImage Viewing骨架显示Membership
Product Intro
Tap one button and let AI read the pose - it draws the human skeleton right on the video. Whether the move is standard, where the power goes wrong - it's all clear at a glance. Pair two videos on one screen to make professional action teaching more intuitive and more effective.

The Universal Edition is a portable, no-install app with all components built in — just download, unzip and run, no extra setup. Below, every core feature is explained with images; click any feature above to jump to its section.
① AI Action Recognition: draws the full-body skeleton in one click
Main screen after analysis: the video is frozen at the take-off instant with the full-body skeleton overlaid
1
Open a video: click "Open Video" to load a recording (MP4 / AVI / MOV).
2
One-click recognition: click 'Action Recognition' and the AI draws the full-body skeleton frame by frame.
3
Video precheck: before recognition begins, the system checks video quality item by item (decodable, resolution, duration, brightness, sharpness and more).
Video precheck before recognition: checks whether the clip is decodable, its resolution, duration, brightness and sharpness item by item, then proceeds to recognition
② Skeleton Overlay: multiple styles show the pose clearly
Skeleton overlay: joints and bone lines are clearly drawn over the video, making the pose obvious
Joints: key joints across the body marked with dots
Bone lines: joints connected following human anatomy, making the pose obvious
Adjustable style: freely set the color, size and thickness of joints and lines
③ Motion Trajectory: records the movement path
Trajectory tracking: the joints' movement path is drawn on the frame, so the motion route is clear
Four styles: solid / dashed / gradient / glow, switch at will
Path trails: the joints' movement path is visualized, making the trajectory clear
Show as needed: toggle the trajectory for specific joints individually
④ Dual-Video Comparison: student vs standard demo
Dual-video AB window: two clips side by side in sync, frozen at the same instant
1
Enter dual video: click 'AB Window' to split the main window into two panes.
2
Synchronized playback: both clips play in sync, with slow motion and frame-by-frame replay.
3
Synchronized compare: both skeletons are shown together so differences are visible frame by frame.
⑤ Video Player: smooth multi-format playback
Video player: open a clip and play it back smoothly, with slow motion and frame-by-frame replay
Many formats: MP4 / AVI / MOV and more open and play directly
Speed control: slow motion and frame-by-frame replay to see key moves clearly
Position control: drag the progress bar or jump to a frame to find the key instant fast
⑥ Image Viewer: freeze a single frame for a clear look
Image viewer: import a key-move screenshot and zoom in for a closer look
Direct viewing: import and view JPG / PNG / BMP images directly
Frame freeze: bring in a key-move screenshot and analyze it with the skeleton
Zoom in: magnify the details and miss no power point
⑦ Joint Angle Display: power and posture deviations at a glance
Joint angle display: draws angle arcs and values at the joints in real timeDisplay settings panel: switches for angles, center of gravity, body silhouette and more at a glance
Live angles: draw angle arcs and values at the joints in real time
Per-part switches: control shoulders, arms, legs and torso independently
Works with the skeleton: shown together with the skeleton, without affecting other rendering
⑧ Center of Gravity: stability at a glance
Center of gravity: marks the body's center of gravity, moving with the action in real time
COG marker: marks the body's center of gravity on the frame
Moves with the action: the COG shifts in real time, intuitively showing balance
Independent switch: can be enabled alone, no interference with skeleton/silhouette
⑨ Body Silhouette Rendering: semi-transparent skin/muscle look
Body silhouette rendering: draws a semi-transparent body outline along the real contour
Real contour: draws a semi-transparent body shape frame by frame along the real outline
Film texture: supports edge blur and opacity adjustment
Toggle anytime: overlays with the skeleton and starlight skeleton without interference
⑩ Starlight Skeleton Preset: a more expressive pose
Starlight skeleton: a semi-transparent blue spirit film + glowing star-trail lines + bright star jointsRender settings: enable the starlight skeleton in the 'Render Presets' group
One-click switch: enable the starlight skeleton in 'Render Settings → Render Presets'
Starlight effect: spirit film + star-trail lines + star joints
No interference: freely combine with the skeleton and body silhouette
⑪ Trajectory Waveform: plots the motion path as curves
Trajectory waveform: click 'Trajectory Waveform' to open a separate window showing each joint's path as curves
Separate window: click 'Trajectory Waveform' to open the curve window
Per-joint view: each joint's path shown as a waveform curve
Zoom & overlay: supports zoom and overlaying multiple curves to inspect the rhythm
⑫ Video Trim & Picture Adjust: cut clips, straighten the frame
Video trim + picture transform: set start/end frames to cut a clip, rotate/mirror to straighten the frame
Video trim: set start/end frames to cut a key clip and save it, original file untouched
Rotation: rotate by any angle to straighten the shooting angle
Horizontal/vertical mirror: flip with one click, switching the viewing side as needed
⑬ Theme Skins: four themes to switch freely
Theme skins: switch instantly among blue, dark, vivid orange and fresh green
Four skins: blue, dark, vivid orange, fresh green
Instant effect: switch via the 'Settings → Skin' menu
Auto-remembered: saved automatically and restored on next launch
⑭ Membership Unlock: unlocks all core features
Membership center: check authorization status, buy online or enter an activation code
Easy activation: buy online in the membership center or enter an activation code
Per-device activation: unlocks action recognition and other core features on this device
