What Makes the FLUX.3 Video Generator Different
Released in July 2026 by Black Forest Labs, the FLUX.3 Video Generator is a multimodal foundation model that learns from footage, stills, and sound inside one shared architecture. It renders 20-second audiovisual clips, reads subtle facial emotion, and scores above rival video models in early preference tests — all powered by the Self-Flow training method.
- Unified Cross-Modal LearningBecause it trains on motion, imagery, and sound at the same time, the FLUX.3 Video Generator grasps how these elements behave together in the real world.
- Built-In Sound, 20 Seconds LongEach clip from the FLUX.3 Video Generator arrives with matching audio — effects, spoken lines, and room tone rendered in the same pass as the picture.
- Scene-to-Scene ContinuityStitch separate shots into multi-minute stories while keeping characters recognizable, thanks to reference-driven output from the FLUX.3 Video Generator.

Six Capabilities That Define the FLUX.3 Video Generator
From text and image prompts to clip restyling, keyframe transitions, and chained multi-shot storytelling, the FLUX.3 Video Generator covers five workflows in one model — and outranks several leading competitors in early preference evaluations.
Five Modes, One Engine
Text, image, and video inputs, keyframe transitions, and audio continuation are all handled natively by the FLUX.3 Video Generator.
Expressive Human Performance
The FLUX.3 Video Generator renders delicate facial cues, multilingual speech, and emotional range that early benchmarks rank above competing models.
Self-Flow Training Backbone
Black Forest Labs built the FLUX.3 Video Generator on a Self-Flow recipe that unifies generation and understanding inside one underlying network.
Strong Head-to-Head Results
In early comparisons, 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 Speech and On-Screen Text
Dialogue in multiple languages and clean typography render reliably, covering looks from handheld camcorder footage to full animation with the FLUX.3 Video Generator.
Open Weights on the Roadmap
Black Forest Labs intends to ship FLUX 3 Dev, an open-weight multimodal backbone, alongside API access to the FLUX.3 Video Generator.
FLUX.3 Video Generator: Questions Answered
Quick answers about what the FLUX.3 Video Generator can do, how long its clips run, and where to access 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 together. The FLUX.3 Video Generator returns 20-second clips with native sound, detailed human expression, and five distinct generation modes.
How does it differ from other video models?
Most systems train on visuals alone. The FLUX.3 Video Generator learns cross-modal rules instead — impacts carry matching sound, motion follows physics, and expressions stay stable — because every modality is trained at once using Self-Flow.
Which generation modes are available?
Five: text-to-video, image-to-video for continuation or reference, video-to-video restyling, keyframe-to-video transitions, and audio-video continuation — all offered by the FLUX.3 Video Generator.
Does it produce sound as well?
Yes. Every result from the FLUX.3 Video Generator ships with synchronized audio — effects, spoken dialogue, and ambient background — so no separate dubbing or post-production sync is needed.
How long can the videos be?
A single pass from the FLUX.3 Video Generator yields up to 20 seconds. By chaining reference-based shots, you can assemble multi-minute sequences that keep the same characters throughout.
Will FLUX 3 be open source?
Black Forest Labs plans to publish FLUX 3 Dev as an open-weight multimodal backbone. Until then, the FLUX.3 Video Generator is reachable through early-access API and private weights on bfl.ai.
