The Multimodal Model Behind the FLUX 3 Video Generator
Black Forest Labs' FLUX 3 Video Generator is one multimodal foundation model trained on video, image and audio data together. Launched in July 2026, it renders 20-second audiovisual clips, captures subtle facial expression, and scores top preference marks against rival video models through its Self-Flow training method.
- Simultaneous Cross-Modal LearningBecause it learns from video, image and audio data at the same time, the FLUX 3 Video Generator grasps how movement, imagery and sound connect in the real world.
- Built-In Audio, Up to 20 SecondsSound arrives with the picture: each clip from the FLUX 3 Video Generator ships with matched effects, spoken lines and background ambience created together with the visuals.
- Chained Multi-Shot StorytellingStitch separate shots into multi-minute narratives while keeping the same characters across scenes, thanks to reference-driven generation in the FLUX 3 Video Generator.
Step-by-Step: Using the FLUX 3 Video Generator
Follow four quick steps to produce multimodal clips with matched sound across five modes in the FLUX 3 Video Generator.
What the FLUX 3 Video Generator Can Do
A single model covers text-to-video, image-to-video, video-to-video, keyframe transitions and agentic multi-shot chaining. Even before release, the FLUX 3 Video Generator earned higher preference scores than several leading rivals.
Five Ways to Generate
The FLUX 3 Video Generator handles text-to-video, image-to-video continuity, video-to-video restyling, keyframe-to-video transitions and audio-video continuation.
Lifelike Human Expression
Subtle facial cues, dialogue in multiple languages and fine emotional detail all come through in the FLUX 3 Video Generator, beating rival models in early tests.
Self-Flow Training Design
Using Black Forest Labs' Self-Flow method, the FLUX 3 Video Generator keeps multimodal generation and comprehension aligned inside one underlying model.
Strong Head-to-Head Scores
In early matchups, the FLUX 3 Video Generator was favored over Grok Imagine Video 69% of the time, Runway Gen-4.5 77%, and Luma Ray 3.2 93% — and it is still getting better.
Multilingual Dialogue and Typography
The FLUX 3 Video Generator renders accurate dialogue across languages and crisp on-screen type, covering looks from handheld camcorder footage to animation.
Planned Open-Weight Backbone
Black Forest Labs intends to ship FLUX 3 Dev, an open-weight multimodal backbone, together with API access to the FLUX 3 Video Generator.
FLUX 3 Video Generator: Frequently Asked Questions
Answers to frequent questions 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's a multimodal foundation model from Black Forest Labs that learns from video, image and audio data together. The FLUX 3 Video Generator turns out 20-second audiovisual clips with built-in sound, lifelike expression and five creative modes.
What makes it different from other video models?
Most models train on video only. The FLUX 3 Video Generator instead picks up cross-modal rules — impacts carry matching sound, motion follows physics, expressions stay steady — because it learns from every modality at once through Self-Flow.
Which generation modes are supported?
You can run text-to-video, image-to-video (as continuation or reference), video-to-video restyling, keyframe-to-video transitions and audio-video continuation from an input clip in the FLUX 3 Video Generator.
Does the tool generate audio as well?
Yes. Each result from the FLUX 3 Video Generator arrives with matched audio built in — effects, spoken dialogue and ambient sound — so there's no extra audio pass or manual syncing.
How long can the videos run?
A single run of the FLUX 3 Video Generator yields up to 20 seconds. With reference-based agentic chaining you can join clips into multi-minute sequences that keep the same characters.
Will FLUX 3 be 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 an early-access API and private weight access on bfl.ai.
