CompAdapt: Adaptable Composite Motion Modeling for Physics-Consistent Text-to-Video Generation

While diffusion-based text-to-video (T2V) models have demonstrated impressive capability in generating realistic and temporally coherent videos, they often fail to respect fundamental physical dynamics. Although recent physics-constrained methods incorporate explicit dynamics priors to improve physical plausibility, th...

AViTS: Adaptive Spatiotemporal Token Selection for Efficient Dynamic-Resolution Generation

AViTS models spatial importance via latent-text attention and temporal importance via token-level feature variation across diffusion timesteps, and fuses them to enable spatiotemporal importance-aware selective upsampling: it prioritizes resolution refinement for critical tokens while deferring less important ones, the...

LinCa: Accelerating Diffusion Models via Learnable Decomposed Feature Caching

LinCa decomposes cached features into sub-components with distinct continuity properties via a lightweight invertible network and applies differentiated prediction orders matched to each component, forming a unified Decompose-Predict-Reconstruct pipeline.
