PermaVid revisit benchmark · span 0.33 (slow / small-motion)

Span 0.33 revisit — video, degradation, and same-pose model comparison

The slow-sweep setting (span_frac = 0.33): the camera moves gently and revisits observed viewpoints. Each scene has every method as a playable video (progress bar + 0.25–1× speed), a multi_visit degradation curve (per-frame PSNR with revisit frames shaded), and a same-camera-pose comparison ranking all models at the returning pose.

▶ Play all fires every method in a scene in sync (kept frame-aligned to the GT clock). Drag the GT progress bar to scrub the whole scene together; the speed buttons apply to all at once.

🎬 The condition (what every method is given): the first 36 observed frames (the blue CONDITION clip in each scene) + the full 180-pose camera trajectory (intrinsics K + per-frame camera-to-world). The task: generate the remaining 144 frames following that exact path — which loops back to observed viewpoints, so it tests whether the model remembers the scene on return.
