About this model
FLUX 3 Image-to-Video animates a still image into a cinematic clip with optional native synchronized audio, using Black Forest Labs' unified image/video/audio architecture. Motion stays physically grounded and consistent with the source frame, making it well suited for product animation, portrait bring-to-life effects, and scene extension. Pair it with FLUX 3 Video Extend to keep building on the generated clip, or compare against Kling 3.0 and Wan 3.0 for image-to-video generation.
