FLUX.3 Image to Video by Black Forest Labs brings a still to life, using your image as the opening frame and generating motion plus matching audio from your prompt. Describe how the scene should move and what it should sound like, then choose a duration from 5 to 20 seconds at 720p or 1080p in aspect ratios from 21:9 to 9:16. Speech, sound effects and music are created in sync with the action, and the source subjects stay consistent. Ideal for animating product shots, key art, characters and concept frames for ads, games and film.
