Why did tracking drift off the pitch after a good start? What if the camera moved?

The field boundary (ROI) uses image coordinates from setup; it does not automatically follow a changed camera viewpoint just because the pitch is the same. The old boundary may include off-pitch passes, substitutes or a neighbouring pitch. Tracking drift can have other causes too; check the original recording and any changes in camera position.

1. 1

   Choose the final position, tripod height and direction, keep the camera level and lock the fittings. Check that both halves are visible. Do not move the camera or tripod after completing setup.

2. 2

   Open Set field in the Ballr App, or the field-confirmation page for your workflow. Check that the panorama shows the new viewpoint; do not redraw over an old screenshot.

3. 3

   Confirm the far-left, near-left, near-right and far-right corners and the lowest point of the near touchline. Match the real boundary, exclude off-pitch areas, save and check the status. Choosing a pitch size does not replace redrawing the boundary.

• Stop unsafe use. To inspect the mount, safely lower the tripod as instructed and support the camera before checking the tripod, quick-release fitting and locks. Do not release a raised mount or carry a fully extended tripod.
• Once stable, check the view and set the field again if position or direction changed. Redrawing cannot fix persistent shaking. Stop use and contact Ballr Support if anything remains loose or damaged. Still trees do not rule out a tripod or mount problem.

• Note the recording time of the movement and retain the original video and views before and after it. Overwriting one boundary does not necessarily fix both viewpoints within the same recording.
• For a planned move, use a break in play to stop and save the current recording, then safely reposition and secure the camera. Start a new recording and use Set field again in the recording menu. Recording continues during setup; check the timer and save status.

1. 1

   If you need to move the camera during a live session, end the stream normally in the App and confirm it has ended before repositioning safely. Do not keep streaming with the old boundary.

2. 2

   Follow the current live workflow to confirm the field again using the new live image, reselect the points and save. Complete preflight, restart the stream and check the viewer picture. This interrupts the stream; it is not a seamless camera move.

• For uploaded footage, submit a field correction or tracking-optimization request in Ballr Hub. Include the recording time of the move, views before and after it and the affected segment. One static boundary cannot automatically cover several viewpoints. Contact Ballr Support if unsure.
• Keep the original video; do not delete or repeatedly upload it to troubleshoot. Saving a boundary or submitting a request is not proof that past footage is fixed. After processing finishes, review the reported timestamps to verify the result.
