Kubric-4D — qualitative by difficulty bin (clean GT)

Each bin is the change in camera optical-axis direction from the input view (30° small near-view shift … 180° full back-view), grouped easy→hard so extrapolation degradation is visible top-to-bottom. Each clip is a grid of individual native-res videos (576×384 Kubric / larger for baselines), ending with the real clean GT target view (fully synthetic scene, so true GT with no warp/inpaint confound). Shape-of-Motion is a per-scene 4D-GS reference fit only on a subset of scenes; elsewhere its tile is marked n/a.

Kubric-4D difficulty sweep (25 clips × 5 bins)
