MiniMax H3 first-and-last-frame video: upload a first frame and a last frame (JPG/PNG/WebP) plus a prompt, and the model infers the motion path, character actions, camera changes and scene transition in between, producing a smooth, detailed bridging clip. Supports 1–15 second clips in 736p portrait, landscape or 1:1, billed per second. Ideal for AI animation, ad creative, storyboarding, product demos and transitions.
