Details
LongVie 2 is an advanced AI model that can generate ultra-long videos up to 3-5 minutes in duration. It is driven by world-level guidance, integrating both dense and sparse control signals, to enable controllable video generation. The model is trained using a degradation-aware strategy to maintain long-term temporal consistency during the extended video generation process. It also incorporates history-context modeling to further enhance the coherence and realism of the generated videos. This represents a significant advancement in the field of video synthesis, enabling the creation of longer, more coherent, and more controllable AI-generated videos.
