Performs smooth video generation between specified starting and ending frames using MiniMax H3. By conditioning on both reference images, the workflow preserves key visual details while creating coherent motion and natural transitions from the first frame to the last. An acceleration LoRA is integrated to improve generation speed and efficiency while maintaining visual quality. This workflow is ideal for controlled transitions, character motion, scene evolution, and other tasks requiring precise first-to-last frame guidance. Generating a 5-second video costs approximately $0.09 and takes around 1.5 minutes.
