VDOT++: Unified Few-Step Video Generation via Unbalanced Optimal Transport Distillation

Video creation spans text-to-video (T2V), image-to-video (I2V), and condition-based generation, yet video diffusion models remain costly because they repeatedly evaluate large backbones during sampling. Distribution matching distillation (DMD) reduces this cost, but its reverse Kullback--Leibler (KL) objective can prov...

Vorch-Streamer: Extending Human Audio-Visual Generation to Real-Time Long-Form Streaming

Vorch-Streamer, a post-training framework that addresses real-time long-form Text-to-Audio-Video (T2AV) streaming and enables real-time long-form avatar audio-video streaming, and bounded causal context and four-step denoising are presented.

Diff-VF: Training-free High-quality Long Video Generation via Diffusion Model

Diff-VF, a training-free, plug-and-play and model-agnostic framework that converts existing short-video diffusion backbones into long-video generators without modifying or fine-tuning the base model, is proposed.

DeforM: Reasoning-Guided Physics-Aware Video Generation via Spatial-Temporal Masking

DeforM is proposed, a reasoning-guided image-to-video generation framework that directs the model's focus toward physics-critical regions, and introduces a VLM-guided physical reasoning module, DeforM-Reason, to identify target objects and generate spatial-temporal masks.
