<h3>🚀 Why CROWN HyperPDMD-HD? (Solving 3–4 Step Collapse &amp; Q4 Quantization Blur)</h3>
<ol>
 <li>True 3–4 Step Trajectory &amp; Mid-Clip Sharpness up to 15 Seconds (<code>362f @ 24fps</code>): Standard 3–4 step MiniMax H3 without LoRA freezes on single-frame I2V, melts into faceless blobs on pure T2V, and suffers severe ghosting/blur in the middle 5s–10s of 15-second FL2V clips (<code>Laplacian = 22 ~ 48</code>). CROWN HyperPDMD-HD delivers <code>6.5× ~ 10×</code> higher optical sharpness with full dynamic motion and synchronized <code>32kHz</code> stereo dialogue audio in just 3–4 Euler steps (<code>CFG = 1.0</code>).</li>
 <li>Online Multi-Precision De-Quantization Training (<code>BF16 + ConvRot INT8 + GGUF Q4_K_M</code>): Distilled on <code>8×NVIDIA B200</code> clusters using Projected Distribution Matching Distillation (<code>HyperPDMD</code>) + 5-frame 3D-Conv VideoVAE spectral discriminator while dynamically perturbing student base weights across <code>45% GGUF Q4_K_M</code>, <code>35% Block-256 Hadamard ConvRot INT8</code>, and <code>20% Pure BF16</code>. Eliminates 4-bit quantization haze while adding <code>0.00 GB</code> extra VRAM when loaded with <code>UnetLoaderGGUFAdvanced (patch_dtype="target")</code>.</li>
 <li>Compact Energy-Optimal SVD Rank Compression (<code>~345 MB</code> vs <code>2.0–3.9 GB</code> Bloated LoRAs): Compressed from <code>Rank-64</code> Cosine-Tail Checkpoint Soup via exact FP64 QR-SVD to <code>avg_rank = 38.0</code> across all 208 DiT + TokenRefiner layers (<code>comfy.lora.load_lora = 208/208 = 100%</code>), retaining <code>99.96%–99.98%</code> Frobenius energy at 1/10th the file size.</li>
