Meet the FLUX 3 Video Generator
Built by Black Forest Labs, the FLUX 3 Video Generator is a single architecture that absorbs video, stills, and sound at the same time. It renders 20-second clips with matched audio, keeps facial detail lifelike, and outranks rival models in blind preference tests thanks to its Self-Flow training method.
- Trained Across Every ModalityBecause the FLUX 3 Video Generator studies picture, sound, and movement in parallel, it grasps how the three connect in the real world.
- Sound Baked Into Every ClipDialogue, ambient noise, and effects arrive already matched to the visuals in each FLUX 3 Video Generator result — no separate audio pass needed.
- Link Clips Into Long StoriesUsing reference-based generation, the FLUX 3 Video Generator lets you stitch scenes into multi-minute narratives while keeping characters on-model.
Getting Started with the FLUX 3 Video Generator
Five input modes, one simple workflow — see how fast the FLUX 3 Video Generator turns an idea into a finished audiovisual clip.
What the FLUX 3 Video Generator Can Do
A single engine covers five creation paths — prompt-to-clip, image animation, restyling, keyframe bridging, and multi-shot chaining. Even in development, the FLUX 3 Video Generator beat major rivals in early preference tests.
Five Creative Modes
Prompt-to-video, image continuation, clip restyling, keyframe bridging, and audio-video extension all live inside the FLUX 3 Video Generator.
Lifelike Human Faces
Facial nuance, emotional shading, and multilingual dialogue come through clearly — the FLUX 3 Video Generator edged out rivals in early benchmarks.
Self-Flow Foundation
Black Forest Labs' Self-Flow method lets the FLUX 3 Video Generator unify generation and understanding inside one underlying model.
Wins in Blind Tests
Early reviewers 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% — and it keeps improving.
Accurate Text and Speech
From candid camcorder looks to animation, the FLUX 3 Video Generator renders multilingual dialogue and on-screen typography with precision.
Open Weights on the Way
An open-weight multimodal backbone, FLUX 3 Dev, is planned alongside API access to the FLUX 3 Video Generator.
Answers About the FLUX 3 Video Generator
Quick answers on what the FLUX 3 Video Generator does, how it handles sound, and how long its clips can run.
What exactly is the FLUX 3 Video Generator?
It's a multimodal model from Black Forest Labs that studies video, images, and audio side by side. With it you can produce 20-second clips that already carry sound, lifelike faces, and five different generation modes.
How does it differ from other video models?
Most video models only ever see footage. This one is trained on all modalities at once through Self-Flow, so it picks up cross-modal rules — a slam sounds like a slam, movement follows physics, and faces stay consistent.
Which generation modes are available?
Five paths are available: prompt-to-video, image-to-video for continuation or reference, clip restyling, keyframe-to-video bridging, and audio-video extension from a source clip.
Does it create its own audio?
Always. Each result ships with matched sound — effects, spoken lines, and background ambience are generated together with the picture, so there's nothing to sync afterward.
What is the maximum clip length?
One pass yields up to 20 seconds. By chaining clips through reference-based generation, you can build multi-minute sequences while keeping the same characters throughout.
Will FLUX 3 be open source?
An open-weight backbone called FLUX 3 Dev is planned. For now, access is offered through an early-access API and private weights on bfl.ai.
