What is Flux 3?
Flux 3 is the first AI video model from Black Forest Labs, the team behind the Flux image models. It is a multimodal video generator that produces clips up to 20 seconds long in a single generation, with native audio created alongside the picture. You describe the shot, drop in a starting image, or set keyframes, and Flux 3 returns a finished clip with sound. On MagicShot, that means one long take instead of stitching four short ones together.
How Flux 3 works inside MagicShot
Flux 3 covers the jobs that usually need three separate tools. Feed it a prompt for text-to-video, a photo for image-to-video, a reference clip for video-to-video, or a first and last frame for controlled transitions. It outputs HD video with Full HD available through upscaling, across wide, square, and vertical aspect ratios, so a single generation can serve a landscape ad and a 9:16 Reel.
Why the 20-second single pass matters
Most models cap out at 5 to 10 seconds, so a longer scene means chaining clips and fighting drift between them. Flux 3 renders the whole 20 seconds at once, keeping the subject, motion, and audio consistent from the first frame to the last. Black Forest Labs positions it against models like Seedance 2.0 on quality and length.
Best uses
Product and ad clips: animate a single product shot into a 20-second spot with sound.
Social video: one prompt into a vertical clip for TikTok, Reels, or Shorts.
Story scenes: set a first and last frame and let Flux 3 fill the transition.
Image to motion: bring an existing still or Flux render to life without a reshoot.
Flux 3 is one of many models available on a MagicShot paid plan, so you can move from prompt to finished clip without a camera, a crew, or a separate video subscription.
