RALLYSCOPE
Pickleball rally analysis
RALLYSCOPE is a free AI Skill for Claude Code, Codex and Cursor that turns a pickleball rally into an analysis video with a light-trail ball and player scores. Upload one fixed-camera pickleball or tennis rally. All four players are tracked as glowing skeletons, the ball flies with a light trail, every strike gets a speed and a placement, and the rally ends with a scored report on who played the most professionally and what each player should work on, delivered as a video and an interactive page.
What's included
- An analysis video: holographic court, glowing skeletons, the ball's light trail, a shockwave and callout for every strike
- An interactive page with the same overlay plus the scored report and improvements for all four players
- Analysis scripts and the page template
Perfect for
- Pickleball and tennis coaches
- Club and team social content
- Players who want to see their own positioning
What you need
- A fixed-camera rally with the whole court in frame
- Raw footage without an existing overlay works best
- Claude Code, Codex or Cursor
Methods and research
Model
- MediaPipe Pose (BlazePose): a 33-keypoint body model, each player tracked frame by frame in their own cropBazarevsky et al., CVPR Workshops (2020)
Measurement
- A homography from the four court corners turns pixels into metres; shot speed is the distance between the two hitters divided by flight timeHartley & Zisserman, Multiple View Geometry in Computer Vision (2004)
Positioning, movement, knee angle and paddle height are measured from the tracked keypoints and the court coordinates; shot speed is the average over the flight. Scores describe this one rally, not a player's level.
FAQ
Paste it into Claude Code, Codex or Cursor and point it to your rally video. The AI downloads the analysis scripts, sets up the tools in a separate environment and builds the video and the page in your project folder. How Skills work
Player positions, knee angles and paddle height are measured frame by frame from 33 tracked points and the court coordinates; shot speed is the distance between the two hitters divided by flight time. Scores describe this one rally, and the far players are smaller on screen, so their angles are coarser.
No. The Skill runs inside your own AI tool, and your video never reaches Sketchry.
