FLUX.3 Image to Video Draft by Black Forest Labs is the fast, low-cost preview mode for image to video: use your still as the opening frame and generate a quick draft, with native synchronized audio, to explore how it should move. When a draft lands, re-render it at full quality on FLUX.3 Image to Video and it keeps the same subjects, composition and motion. Supports durations from 5 to 20 seconds in aspect ratios from 21:9 to 9:16. Ideal for testing motion on product shots, key art and characters before a final render.
