+
+This five-second, 24 FPS test starts with a public 1280×720 Seedance 2.0 action
+generation: a running puppy, tracking camera, fur, grass, flowers, and a moving
+butterfly. A deterministic product-demo HUD is added before downsampling so the
+test also contains the small labels, cards, and buttons this model targets. The
+reference is downsampled and encoded to a real 640×360 input; bicubic and Clark
+then receive the same decoded frames.
+
+Across all 120 frames:
+
+| Measure | Bicubic x2 | Clark x2 | Gain |
+|---|---:|---:|---:|
+| RGB PSNR | 32.482 dB | 33.185 dB | +0.703 dB |
+| Edge PSNR | 17.986 dB | 20.659 dB | +2.673 dB |
+| Temporal-delta PSNR | 38.520 dB | 37.598 dB | -0.922 dB |
+
+The moving test therefore confirms stronger per-frame reconstruction and edge
+recovery, while also exposing a real remaining gap: this frame-independent
+student does not yet match bicubic's temporal-delta fidelity. The source,
+separate bicubic and Clark outputs, held-out reference, exact prompt, seed,
+hashes, crop, and metric definitions are all included under
+`examples/seedance-action/` and `technical/seedance-action-video-evaluation.json`.

 The left column is the actual low-resolution source before either scaler is applied. The middle and right columns both start from that exact source. A held-out high-resolution frame is used only for PSNR measurement; it is not shown or mislabeled as the input.
