Splatastic — how to film
Seven rules for a walkthrough that can be reconstructed. 0.5× first.
1. 0.5× — ultra-wide
Never 1× or tele: 1.47 px loop error measured at 0.5×, while the same walkthrough stayed unsolved at 1×.
2. 4K60, HDR and action mode off
Resolution and frame rate high; everything that smooths, stabilises or lifts contrast afterwards, off.
3. Lock exposure and focus, lights on
Set the AE/AF lock before you start — and do not film into the sun or a window.
4. Walk slowly, never just pan
Keep the phone at the same height and walk a curve instead of turning on the spot. A short pause is fine, standing still for minutes is not: it only yields duplicates and pushes the revisits out of the memory of the pose solver.
5. Close the loop
Walk 3–5 m past your starting point so the loop closes unambiguously.
6. Pause briefly in doorways
Show every passage twice — from both sides — and on white, featureless walls keep an edge in the frame.
7. One pass per room, halls in sections
One dedicated pass per room; split large halls into 3–5-minute sections instead of one long take.
