Flux 3 Video is a third-party site for using FLUX 3, the first video model from Black Forest Labs. You upload a frame, describe the shot, and get a clip of up to 20 seconds at 1080p, with sound generated in the same pass.
A cheaper draft mode makes 720p previews so you can test ideas, then re-render the take you like at full quality. Free credits are available to start, with no card and no watermark.
