FLUX 3: Dedicated for Scenes with Motion and Sound

Text-to-video suits a scene you have not designed yet. Describe the subject, setting and action, then add the camera direction that matters to the shot. Image-to-video is useful when the composition already exists and you want to decide what happens next rather than rebuild the opening frame through words alone.

With an image input, use the prompt to explain motion and intent. A detailed description of every visible object can obscure the action you actually want. Focus on what changes during the clip: a person turns toward the camera, fabric moves in the wind, or the viewpoint moves closer to a product.

A first frame establishes where the shot begins. A first-and-last-frame setup also tells the model where it should arrive. For more structured transitions, our FLUX 3 Video workflow accepts up to 10 timeline keyframes.

Pin keyframes at the moments that define your transition: the opening pose, a change in composition and the final image. Keep the same subject, lighting and visual style across the references for a continuous scene. For transformations, use the intermediate frames to show the intended progression.

Native audio lets you describe a scene as an audiovisual event. Dialogue, background ambience and sound effects can be part of the same direction as the visible action. A conversation in a quiet room and a product reveal in a busy workshop need different sound environments even when the camera movement is similar.

FLUX 3 supports multilingual dialogue. Specify the spoken language, exact line and speaker action in the prompt. Include the intended vocal delivery, such as a quiet conversation or an energetic introduction, alongside the camera and sound directions.

A single FLUX 3 generation runs for up to 20 seconds. Give each clip one main action and a clear beginning and ending. Split dialogue exchanges, major transformations and changes of location into separate shots so you can control their order and pacing in the edit.

Reference images establish the subject and composition. During review, check faces, hands, product edges, repeated objects and visible text throughout the clip. Use matching reference frames for recurring characters and products, and keep the motion focused on the action the shot needs.

Add final logos, required disclosures and fixed-layout text during editing or compositing. This keeps exact brand assets separate from generated movement and gives you direct control over their placement and legibility.

Review the spoken words, pronunciation, background sound and timing alongside the picture. For a scene that needs revised dialogue or a different sound mix, adjust the audio direction before generating another version. Select the clip whose performance and sound match the intended scene.
