Researchers have developed DSAQuant, a novel quantization-aware training framework specifically designed for video diffusion models (VDMs). This method addresses the degradation of visual details and texture fidelity often seen in quantized VDMs by aligning the training and inference processes with the stage-wise nature of video denoising. DSAQuant employs Denoising-Stage Oriented Supervision to maintain stable structure planning in early stages and target-driven optimization for detail reconstruction in later stages, while Denoising-Stage Gated Guidance mitigates quantization errors during inference. Experiments show DSAQuant significantly outperforms existing methods on the Wan and CogVideoX families, improving VBench scores under aggressive quantization settings. AI
