Square the view.
Put the camera directly side-on near seat height. Start about 2–3 m (7–10 ft) away, then adjust for your room, lens, body, and erg.
Side-view camera setup · Guide 06
I want RowCoach to see the whole stroke.
Give the camera one stable, square view from head to strapped foot at both ends of the stroke. RowCoach handles the warmup from there.
Build a frame the stroke cannot leave.
Place the camera directly side-on, near seat height, and far enough away that the complete catch and finish both fit with breathing room.
View needs work One end is cropped
Ready to row Catch + finish fit
Keep every end point.
Head, moving hands, knee, and strapped foot stay visible.
Warm up hands-free.
- Press Start once.
- Row two or three easy unscored strokes.
- Continue when live coaching begins automatically—no second confirmation is needed.
A useful view is stable, square, and complete.
Use RowCoach from localhost or HTTPS so the browser can grant camera access. Use a camera capable of at least 15 FPS; 30 FPS is recommended. RowCoach may lower the preferred 1280×720 resolution to preserve a usable frame rate.
On a phone, RowCoach prefers the rear camera when the preview opens. If the phone has more than one camera, use Use front camera or Use rear camera before starting the warmup. Camera switching stays out of the live session so it cannot interrupt a stroke.
Stabilize the camera, center the full stroke, use steady lighting, and avoid a bright window behind the rower. If a joint disappears, the pose jumps between sides, or the camera shifts, move the camera or erg and use Reset for a fresh warmup.
The distance and height are a starting point, not a universal placement standard. Wide-angle distortion, room geometry, body proportions, clothing, and working-side occlusion all affect the useful frame.
The camera stays local. The analysis stays bounded.
Privacy and evidence availability are separate promises, and both should be clear before the first stroke.
Video becomes pose landmarks
Pose estimation and camera-video processing occur in your browser. Camera video is not uploaded, recorded, or stored.
Landmarks and timing
Normalized pose landmarks and timing go over an encrypted connection to the protected analysis service, which learns machine direction, working side, and body scale from warmup strokes.
When a check lacks evidence
Keep the strapped foot and knee visible. If lower-body evidence is missing, the completed stroke's technique result shows Learning while supported upper-body coaching can continue. A camera cannot measure force or replace a qualified coach's judgment.
