FLUX 3 Video Generator: A Model Trained on Sight and Sound
Built by Black Forest Labs, the FLUX 3 Video Generator is a single multimodal foundation model that learns from footage, stills, and audio at the same time. Its Self-Flow training method lets one network render 20-second audiovisual clips, hold onto subtle facial expressions, and outscore rival video models in early preference tests.
- Trained Across Every ModalityFootage, stills, and sound enter the same training loop, so the FLUX 3 Video Generator grasps how movement, light, and audio behave together in the physical world.
- Sound Built Into Every ClipAudio is never bolted on afterwards. Each render from the FLUX 3 Video Generator ships with dialogue, effects, and room tone that line up frame by frame.
- Chain Clips Into Longer StoriesReference the same character or setting across separate renders and stitch them together, letting the FLUX 3 Video Generator carry continuity through multi-minute sequences.
Four Steps to Run the FLUX 3 Video Generator
Pick an input style, add your references, and let one engine handle picture and sound together.
Capabilities Built Into the FLUX 3 Video Generator
A single model covers text-to-video, image-to-video, video-to-video, keyframe transitions, and chained multi-shot work. In early head-to-head preference tests, the FLUX 3 Video Generator came out ahead of several established rivals while still in development.
Five Modes, One Engine
Written prompts, image continuation, clip restyling, keyframe transitions, and audio-driven continuation all run through the same FLUX 3 Video Generator.
Convincing Human Expression
Faces, gestures, and multilingual delivery hold up under scrutiny — early benchmarks put the FLUX 3 Video Generator ahead of competing models on emotional nuance.
Self-Flow Training Method
Black Forest Labs built the FLUX 3 Video Generator on a Self-Flow approach that keeps generation and understanding inside one shared network.
Strong Preference Results
In early side-by-side tests, raters favored the FLUX 3 Video Generator over Grok Imagine Video 69% of the time, Runway Gen-4.5 77%, and Luma Ray 3.2 93%.
Dialogue and On-Screen Text
Multilingual speech and rendered typography stay legible, whether the FLUX 3 Video Generator is asked for candid camcorder footage or stylized animation.
An Open-Weight Release Is Coming
Black Forest Labs intends to publish FLUX 3 Dev as an open-weight multimodal backbone, while API access to the FLUX 3 Video Generator is already open.
Questions About the FLUX 3 Video Generator
Answers to the questions people ask most about the FLUX 3 Video Generator and the multimodal model sitting behind it.
What exactly is the FLUX 3 Video Generator?
It is a multimodal foundation model from Black Forest Labs that learns from footage, stills, and audio at once. Renders run up to 20 seconds, arrive with sound already attached, and can be steered through five different generation modes.
How does it differ from other video models?
Most video models only ever see moving pictures. The FLUX 3 Video Generator also learns from audio and still images, which teaches it that impacts should sound like impacts, objects should move the way physics allows, and a face should stay the same face from shot to shot.
Which generation modes are supported?
Five: text-to-video, image-to-video for continuation or reference, video-to-video restyling, keyframe-to-video transitions, and audio-video continuation that picks up from an existing clip.
Does it produce audio as well?
Yes. Every render from the FLUX 3 Video Generator carries its own synchronized soundtrack — dialogue, sound effects, and background ambience — so nothing has to be mixed or synced in a separate step.
How long can a single video be?
One pass from the FLUX 3 Video Generator yields up to 20 seconds. By reusing references and chaining renders together, you can build multi-minute sequences that keep characters consistent.
Will FLUX 3 be released as open source?
Black Forest Labs has said it plans to ship FLUX 3 Dev as an open-weight multimodal backbone. For now, the FLUX 3 Video Generator is reachable through early-access API and private weights on bfl.ai.
