FLUX 3 Max Keyframes-to-Video Tutorial Cover

Create a dynamic cover for the flux-3-max/keyframes-to-video usage tutorial: use a static "tutorial cover" layout as the first keyframe, and let the image complete its own entrance and settle within 10 seconds, forming a looping visual that can be placed directly at the top of a document. The composition retains the layout with a title area on the left and a demo area on the right; the title area is used for overlaying tutorial copy, while the right demo area shows the transitional imagery from a reference image to a video clip. The author's pipeline positions keyframes on a 24fps timeline via the keyframes array; this piece places two keyframes, the first frame and the last frame, and uses duration, resolution, aspect_ratio, and reasoning_level to control output specifications, with synchronized audio generation enabled, making it convenient for direct use in documents or social media previews. Suitable for scenarios such as tutorial covers, product documentation header images, and model family introduction pages that need low-cost dynamic versions of static layouts; it is also suitable as a reference for developers using this model family for rapid creative iteration and storyboard previsualization.
