The model demonstrates remarkable capabilities in executing users’ instructions, maintaining consistency between the first frame and the generated video, and delivering smooth transitions between the first and last frames to generate realistic and natural visuals of complex movements. It enables users to create a five-second video at 720p resolution for free when prompting the model on Wan’s official website.
The key technology behind this model is an innovative approach to video generation by incorporating an additional control adjustment mechanism. This mechanism uses the user-provided first and last frames of a sequence as control conditions, enabling smooth and precise transitions between the start and end frames.
To ensure visual stability, the mechanism helps inject semantic features from the first and last frames into the generation process, enabling the model to maintain consistency in style, content and structure, while dynamically transforming frames.
