SkyReels V2

By Skywork AI

SkyReels V2 combines a structured video representation (high-level descriptions plus shot-level detail), progressive pretraining, and post-training stages including supervised fine-tuning and motion-focused reinforcement learning, then uses a diffusion-forcing framework with non-decreasing noise schedules to enable efficient long-video synthesis. It is described as supporting long duration generation and controls like video extension plus start and end frame control for the diffusion-forcing model.
