FLUX 3 Video: Native Audio, 20s Clips & Workflows

Juli 24, 2026

FLUX 3 Video is Black Forest Labs’ next-generation AI video model for cinematic multimodal creation. It combines native audio, text, image and video inputs, keyframe control, scene continuation, and single generations up to 20 seconds.

The result is a more complete creative workflow: build the shot, direct the sound, guide the opening and ending frames, transform source footage, and continue a strong scene without rebuilding it from zero.

What is FLUX 3?

FLUX 3 is a visual intelligence model family from Black Forest Labs. The company is best known for FLUX image-generation models, but this generation expands the family toward a unified multimodal workflow that covers image and video creation.

For video, the important shift is not one isolated quality claim. It is the combination of:

  • text, image, and video inputs
  • native audio generation
  • first-frame and last-frame control
  • video-to-video transformation
  • video and audio continuation
  • multilingual dialogue
  • typography-aware visual creation
  • agentic chaining across creative steps

That combination makes the video system relevant to filmmakers, product teams, marketers, game studios, agencies, and creators who need more control than a simple one-prompt clip.

How long can one generation be?

Black Forest Labs says the video model can generate up to 20 seconds in a single generation.

The “single generation” detail matters. Several-minute sequences may be possible through chained clips and continuation workflows, but that is different from creating several minutes in one request. A practical 20-second scene can hold:

  • an opening setup and visual payoff
  • a short dialogue exchange
  • a product reveal with camera movement
  • a complete social-ad beat
  • a pre-visualization shot with ambience and sound

Does the model generate native audio?

Yes. Native audio is one of the model’s defining capabilities. The video workflow generates visual and audio content together, including dialogue, ambience, sound effects, and music direction.

That makes sound part of the shot design instead of a separate finishing step. Prompts can describe what the audience should hear, when a sound should happen, and how the audio should support the scene.

Text-to-video prompting

Text-to-video starts from a written scene. A useful model prompt should describe more than the subject:

  1. subject and environment
  2. action and timing
  3. camera movement and framing
  4. lighting and visual treatment
  5. dialogue, ambience, effects, or music direction
  6. intended duration and aspect ratio

Build the complete shot brief in the text-to-video studio, including subject, motion, camera, lighting, pacing, dialogue, and sound.

Image-to-video and keyframes

Image-to-video is useful when a product, person, illustration, character, or composition must remain recognizable. The model also supports first-frame and last-frame control, giving the generation clearer opening and ending boundaries.

Strong keyframe workflows typically use:

  • a clean first frame with the required subject and composition
  • a compatible last frame that describes the desired destination
  • a prompt focused on the transition, camera, and motion
  • audio direction that matches the timing of the shot

Prepare references in the image-to-video studio.

Video-to-video and continuation

The system is designed for both transformation and continuation:

  • Video-to-video transformation uses a source clip to guide motion, rhythm, composition, or a new visual treatment.
  • Video and audio continuation extends an existing audiovisual scene while carrying context into the next segment.

These workflows are central to multi-shot storytelling because creators can work from a previous result instead of rebuilding every scene from zero.

Is this the official FLUX 3 website?

No. flux3video.app is an independent AI video workspace and is not the official Black Forest Labs website. For first-party product announcements and access, use bfl.ai.

Can generated videos be used commercially?

For commercial work, use original or licensed input materials and review the terms attached to your selected generation plan. Before publishing advertising, client work, or monetized content, check:

  • the provider’s current commercial-use terms
  • whether uploaded materials are licensed
  • consent for recognizable people
  • rights to logos, music, characters, and product assets
  • any required provenance or disclosure

Frequently asked questions

Does it support multilingual dialogue?

Yes. Multilingual dialogue expands the model from silent visual clips into character scenes, explainers, ads, and story moments built around spoken performance.

Can it generate readable text?

Yes. Typography-aware generation supports concepts where titles, packaging, interfaces, signs, or branded text are part of the visual composition.
