Small-group motion capture from one phone video
A two-dancer rehearsal clip becomes aligned 3D bodies on a ground plane for timing, spacing, and partner travel review.
Computer vision pipeline
Dance motion capture from a normal practice video
Sway uses computer vision to turn raw rehearsal footage into dancer tracking, identity-aware 3D body meshes, and motion capture review that can help choreographers clean spacing and timing.
- Use regular phone or camera footage as the input, then track dancers through the clip.
- Lift motion into a 3D mesh world so spacing, travel paths, and timing problems are easier to inspect.
- Connect video evidence back to Sway formation planning, rehearsal feedback, and future motion capture workflows.

Motion capture video examples
Team-scale tracking through a crowded formation
A nine-dancer practice video becomes a readable 3D world for formation cleanup and motion capture review.
Phone-first video to full-body 3D motion
Portrait rehearsal footage produces dancer-specific mesh motion without studio suits, markers, or a capture volume.
Frequently asked questions
Can Sway use regular dance videos for motion capture?
The CV pipeline is designed around normal practice footage: a phone or camera video is analyzed for dancers, identities, poses, and 3D body motion instead of requiring studio markers.
How is this different from a pose overlay?
A pose overlay shows 2D joints on top of the video. The 3D mesh pass reconstructs body motion in a shared world, which is more useful for spacing, collision checks, formation cleanup, and motion capture review.
