Filming tips

Camera faces your chest at leg lift (RHP: 3B side, LHP: 1B side), at hip height on a tripod. Don't pan or zoom.
Whole body in frame, plain background, good light.
Use slow-mo (120–240 fps). If a slow-mo clip was exported at 30 fps, enter the real capture fps (e.g. 240).
Trim to set position → follow-through. Same spot every session.
Phones are slower than laptops. Keep the screen on while it analyzes.
