Start with footage that has real parallax
Move the phone through the scene instead of only panning from one spot. Camera translation gives the solver real depth information. Avoid heavy motion blur, blank walls, overexposure, and scenes where the only visible detail is moving foreground content.
Convert, track, import, clean, and align
Use Select Footage to convert the video into a sequence. Run Quick Tracking first if you want fast feedback, or Heavy Tracking when quality matters. Import the result, clean floating points, align the floor, then set the footage as the camera background to judge whether the track sticks.
Use masks when people or cars move through the shot
If the footage includes a moving subject, create a SAM2 mask or polygon layer before Heavy Tracking. Tracking the background region helps prevent moving objects from damaging the solve.
