Why Creators Choose the FLUX.3 Video Generator
The FLUX.3 Video Generator from Black Forest Labs is one multimodal architecture that learns from video, images, and audio together. Launched in July 2026, it returns 20-second audiovisual clips, renders subtle human expression, and beats leading video models in early preference tests — all powered by the Self-Flow training method.
- Trained Across Three ModalitiesBecause it studies footage, stills, and sound at the same time, the FLUX.3 Video Generator grasps how movement, imagery, and audio relate in the physical world.
- Sound Comes Built InEvery clip the FLUX.3 Video Generator returns already carries matching audio — effects, spoken lines, and background ambience rendered in the same pass as the picture.
- Chain Shots Into StoriesLink separate clips into sequences minutes long while characters stay recognizable, thanks to the reference-driven generation inside the FLUX.3 Video Generator.
Getting Started with the FLUX.3 Video Generator
Pick a mode, attach your references, and let the FLUX.3 Video Generator build finished footage with sound in just a few steps.
Core Strengths of the FLUX.3 Video Generator
A single model covering text-to-video, image-to-video, video-to-video, keyframe transitions, and multi-shot chaining — the FLUX.3 Video Generator already outranks established rivals in early preference testing, even while still in development.
Five Creative Modes
Text prompts, image continuations, video restyling, keyframe transitions, and audio-video extension all live inside the FLUX.3 Video Generator.
Lifelike Human Expression
Faces, gestures, multilingual speech, and emotional nuance come through convincingly — the FLUX.3 Video Generator topped competitors on exactly these points in early benchmarks.
Self-Flow Training
Black Forest Labs' Self-Flow method lets the FLUX.3 Video Generator align generation and understanding of multiple modalities inside one underlying model.
Strong Preference Scores
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%.
Multilingual Dialogue and Text
Produce accurate speech in multiple languages and clean on-screen typography, from candid camcorder looks to full animation, with the FLUX.3 Video Generator.
An Open-Weight Release Is Coming
Black Forest Labs intends to publish FLUX 3 Dev, an open-weight multimodal backbone, and to offer API access to the FLUX.3 Video Generator.
FLUX.3 Video Generator: Your Questions Answered
Answers to the questions people ask most about the FLUX.3 Video Generator and the multimodal video technology behind it from Black Forest Labs.
What exactly is the FLUX.3 Video Generator?
It is a multimodal foundation model from Black Forest Labs that learns from video, images, and audio together. The FLUX.3 Video Generator returns 20-second clips with sound already attached, expressive human performance, and five different generation modes.
How does it differ from other AI video models?
Most models learn from footage alone. The FLUX.3 Video Generator picks up cross-modal rules — an impact sounds the way it looks, movement obeys physics, expressions stay steady — because it trains on every modality at once through the Self-Flow approach.
Which generation modes are available?
Five of them: text-to-video, image-to-video for continuation or reference, video-to-video restyling, keyframe-to-video transitions, and audio-video continuation that extends an existing clip — all handled by the FLUX.3 Video Generator.
Does it create the audio as well?
Yes. Sound effects, spoken dialogue, and ambient background are rendered in the same pass as the picture, so every FLUX.3 Video Generator result arrives already synchronized — nothing to dub or mix afterwards.
How long can a single video be?
One generation from the FLUX.3 Video Generator runs up to 20 seconds. By chaining reference-based clips together, you can build multi-minute sequences in which the same characters keep appearing.
Will FLUX 3 be released as open source?
Black Forest Labs plans to ship FLUX 3 Dev as an open-weight multimodal backbone. For now, the FLUX.3 Video Generator is reachable through an early-access API and private weight access on bfl.ai.
Put the FLUX.3 Video Generator to Work
See one model handle motion, stills, and sound at the same time — the FLUX.3 Video Generator turns a written idea or a single photo into a finished clip.
