Meet the FLUX.3 Video Generator: One Model for Video and Sound
Built by Black Forest Labs, the FLUX.3 Video Generator is a single multimodal architecture that studies motion, stills, and sound side by side. Launched in July 2026, it returns 20-second clips with audio already attached, reproduces subtle facial detail, and scores above rival video models — thanks to the Self-Flow training method.
- Trained on Video, Stills and SoundBecause the FLUX.3 Video Generator studies all three data types at once, it grasps how movement, imagery, and audio relate to one another in the real world.
- Audio Arrives With the PictureEvery render ships with matching sound — effects, spoken lines, and room tone are produced in the same pass as the visuals, never bolted on later.
- Multi-Shot Sequences From ReferencesLink separate renders into longer narratives while the same characters stay recognizable, using reference-driven generation inside the FLUX.3 Video Generator.
Running the FLUX.3 Video Generator in Four Steps
Choose a mode, add your references, and render sound and picture together in one pass with the FLUX.3 Video Generator.
Core Capabilities of the FLUX.3 Video Generator
One unified model covers text-to-video, image-to-video, video-to-video, keyframe transitions, and agentic multi-shot chaining. Even while still in development, the FLUX.3 Video Generator outpaced leading rivals in early preference tests.
Five Distinct Generation Modes
Text-to-video, image-to-video continuity, video-to-video restyling, keyframe-to-video transitions, and audio-video continuation — all handled by one model.
Expressive Human Performance
Facial nuance, multilingual dialogue, and emotional subtleties come through more convincingly than rival models managed in early benchmarks.
Self-Flow Training Backbone
Black Forest Labs' Self-Flow method lets the FLUX.3 Video Generator align multimodal generation and understanding inside a single underlying network.
Wins in Head-to-Head Tests
Early comparisons favored it over Grok Imagine Video in 69%, Runway Gen-4.5 in 77%, and Luma Ray 3.2 in 93% of cases — and the model is still improving.
Multilingual Dialogue and Typography
Produce clips with accurate multilingual speech and clean on-screen text, spanning looks from candid camcorder footage to full animation.
Open-Weight Release Planned
Black Forest Labs intends to publish FLUX 3 Dev, an open-weight multimodal backbone, alongside API access to the FLUX.3 Video Generator.
FLUX.3 Video Generator: Frequently Asked Questions
Straight answers about the FLUX.3 Video Generator and the multimodal video technology it is built on.
What exactly is the FLUX.3 Video Generator?
It is a multimodal foundation model from Black Forest Labs that studies video, images, and audio together. From a single prompt it returns 20-second clips with native sound, expressive human faces, and five different creative modes.
How does it differ from other AI video models?
Most video models only learn from footage. The FLUX.3 Video Generator also learns from stills and audio, so it picks up cross-modal rules — a slam sounds like a slam, motion obeys physics, and faces stay consistent — through Self-Flow training.
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 generative audio-video continuation that extends an existing clip.
Does the FLUX.3 Video Generator create its own audio?
It does. Sound effects, spoken dialogue, and ambient background come out synced with every clip, so there is no separate audio pass or post-production alignment to worry about.
How long can a single video run?
One generation can reach 20 seconds. By chaining clips with reference-based agentic generation, you can build multi-minute sequences that keep the same characters throughout.
Will FLUX 3 be released as open source?
Black Forest Labs intends to publish FLUX 3 Dev as an open-weight multimodal backbone. For now, the FLUX.3 Video Generator is reachable through early-access APIs and private weight access on bfl.ai.
