Could you build this?
Partial Basic dual-video playback and side-by-side scrubbing is simple to build, but monocular 3D motion capture and kinematic alignment require complex computer vision models.
What it would actually take: The architecture requires WebAssembly/WebGL or WebGPU running pose estimation models (e.g., MediaPipe, MMPose, or custom 3D mesh recovery like SMPL/HMR2). The hard part is accurate monocular 3D spatial reconstruction without depth sensors and robust temporal smoothing across arbitrary camera angles, demanding specialized computer vision and biomechanics expertise.
