Readme
FLUX 3 is Black Forest Labs' frontier video model. The image supplies the opening frame - a single bare keyframe - and the prompt describes how the clip develops from it.
Duration runs from 5 to 20 seconds or auto, at 720p or 1080p, with audio generated by default. Aspect ratio auto lets the model follow the input image.
