<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) &mdash; each method's output plays at its <b>native resolution</b> (no downscaling; e.g. GEN3C 1280&times;704, ViewCrafter 1024&times;576, NVS-Solver/Shape-of-Motion 960&times;540, FrameCrafter/Ours 832&times;480, Kubric 576&times;384). Tiles read left&rarr;right, top&rarr;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 &mdash; where honest ground truth exists &mdash; a <b style="color:#2769b8">GT</b> tile (blue).
