What it's like to use
FLUX 3 is Black Forest Labs' video model: picture and synchronized sound generated together, from a prompt or from a first frame toward an optional last frame, in 5 to 20 second clips at 720p or 1080p. A low-cost draft tier previews a shot, extend continues a finished clip, and upscale enlarges the keeper up to three times.
Good for
- Short dialogue scenes over rain, engines or a crowd
- Bringing a portrait or a product photo to life
- Storyboards drafted cheaply, with only the keepers rendered properly

- Finish the prompt with a line starting "Sound:" naming the rain, the footsteps or the exact words a character says. Quoted lines come back word for word.
- Settle framing and action in the draft tier, then switch to standard quality for the final.
- Keep one action, one camera move and one light change per clip; ask for too much and the model tends to cut.
