kling-2-1/standard/image-to-video
Animate a single image into a smooth video with Kling 2.1 Standard.
MiniMax's MiniMax H3 Fast Reference To Video makes a 5-15 second clip with native audio from a prompt plus up to one reference video and four reference images. MiniMax H3 Fast returns sooner and costs less, but it follows detailed prompt instructions less strictly than the standard MiniMax H3 page. For developers, MiniMax H3 Fast on RunComfy can be used both in the browser and via an HTTP API, so you don't need to host or scale the model yourself.
Ideal for: Draft storyboards | Social clips | Fast iteration
MiniMax H3 Fast bills each resolution below at its own per-second rate. Generation is faster than standard MiniMax H3, and detailed prompt instructions are followed less strictly.
