scene-extrapolation-benchmark

Revisit/memory qualitative: full-res per-method video panels for 6 memory benchmarks (mv/mb x dl3dv/spatialvid/kubric4d, ~10 clips each), lockstep SYNCHRONIZED playback controller on ALL qual panels, and per-clip return-frame comparison (generated-return | observed-GT + reused return/self PSNR/SSIM/LPIPS). Incremental: all prior sections (eval50/nvidia/spatialvid/kubric/lh qual, memory tables, difficulty hero, pose-free curves, fairness, coverage, glossary, story) preserved. [viz_pkg mirror]

	<h2>Qualitative Comparisons</h2>
	<p class="q-intro">Every panel below is a single clip shown as a <b>CSS grid of individual full-resolution videos</b> (max 4 per row) — each method's output plays at its <b>native resolution</b> (no downscaling; e.g. GEN3C 1280×704, ViewCrafter 1024×576, NVS-Solver/Shape-of-Motion 960×540, FrameCrafter/Ours 832×480, Kubric 576×384). Tiles read left→right, top→bottom: <b>Observed</b> input, the geometry-only <b>Warp</b> (point-cloud reprojection with disocclusion holes), key baselines including <b>FrameCrafter</b>, our <b>VACE-14B</b> (green), and — where honest ground truth exists — a <b style="color:#2769b8">GT</b> tile (blue). Videos lazy-load on scroll; press play (they also loop muted). Sections are collapsible.</p>
