About this model
FLUX 3 Image-to-Video animates a still image into a full motion clip — with optional native, synchronized audio — using Black Forest Labs' unified FLUX 3 architecture. Because FLUX 3 is jointly trained across image, video, audio, and action-prediction data, motion generated from a source frame stays physically grounded: objects move the way they would in the real world rather than drifting or warping. This makes FLUX 3 Image-to-Video well suited to product animation, portrait bring-to-life effects, and extending a still shot into a short scene, joining options like Seedance 2 Image to Video already available on Muapi.

It's Black Forest Labs' image-animation mode within the FLUX 3 family — it takes a still image and generates a cinematic video clip, with optional native synchronized audio, using the same unified multimodal architecture as FLUX 3 Video.
FLUX 3 Video entered early access on announcement day; Muapi will enable the image-to-video endpoint once Black Forest Labs opens general API availability.
Yes — because FLUX 3 is trained jointly on image, video, and action-prediction data, generated motion tends to stay physically grounded and consistent with the source frame's geometry and lighting.
Yes, set `generate_audio` to true and FLUX 3 will produce scene-appropriate synchronized audio alongside the animation.
Expect roughly 4–10 second clips at launch based on the announcement and comparable video models, with longer durations likely to follow as the model matures.
FLUX 3 Image-to-Video will join existing options like Seedance 2, Kling, and Veo 3 image-to-video — Muapi will publish head-to-head comparisons once FLUX 3 is generally available.
