I have some weird issues trying to track my footage using a tripod pan shot and one additional helper frame from a different position. I used a Canon 5D with a 75mm lens and there is no visible distortion.
No matter if I enter 50mm or 90mm for focal length, automatic refinement isn’t triggered and the solve error is far too high (>100) and even if i can solve below, 1 the camera movement is plain wrong. I tried manual refinements, the solve error jumps from 43.3 (75.3mm) to 0.555 (75.5mm), or from 78.1 (75.6mm) to 8.3 (80mm)
The solver error between 85-90mm is below 0 but if i control the empties using map reference the angles and distances are very distorted. Enough markers are tracked, I have no more ideas how to solve this.
