For the ground triangle, measure: A ↔ B, A ↔ launch origin, and B ↔ launch origin. These three distances calculate the horizontal headings. Each phone/iPad supplies its camera tilt from the device orientation sensor automatically; positive means the rear camera is aimed upward.

Apple 1080p rear-camera presets are loaded automatically. Rotating a camera only corrects the image orientation — it does not change the saved/calibrated FOV values. You can still type measured/calibrated FOV values below; doing so changes that camera to Custom.

Required alignmentbefore launch

Place A and B on one straight baseline. Keep both phones upright and still. Aim the centre crosshair of each phone exactly at the paper rocket’s launch origin. The program uses that centre point to calculate each camera heading.

Press the button when both videos are buffered. The tracker scans both synchronized clips, follows the rocket, finds its highest synchronized point, and places both tracking dots automatically. Manual clicking can still correct either dot.
