Why the FLUX 3 Video Generator
The FLUX 3 Video Generator is Black Forest Labs' new multimodal foundation model that jointly learns from video, images, and audio within a single unified architecture. Released in July 2026, it produces 20-second audiovisual clips, captures nuanced human facial expressions, and achieves top-tier preference scores against leading video models — all built on the Self-Flow training approach.
- Joint Multimodal TrainingTrained simultaneously on video, images, and audio, the FLUX 3 Video Generator understands how motion, visuals, and sound interrelate in the physical world.
- 20-Second Native AudioEvery FLUX 3 Video Generator output includes synchronized audio — sound effects, dialogue, and ambient tracks generated alongside the visuals.
- Agentic Multi-Shot ChainingChain individual clips into multi-minute sequences with consistent characters across scenes using the FLUX 3 Video Generator's reference-based generation.
How to Use the FLUX 3 Video Generator
Create multimodal videos with synchronized audio in five modes using the FLUX 3 Video Generator.
FLUX 3 Video Generator Core Capabilities
One unified model spanning text-to-video, image-to-video, video-to-video, keyframe transitions, and agentic multi-shot chaining — the FLUX 3 Video Generator outperforms leading competitors in early preference evaluations while still in development.
Five Generation Modes
Text-to-video, image-to-video continuity, video-to-video restyling, keyframe-to-video transitions, and audio-video continuation — all in the FLUX 3 Video Generator.
Superior Human Expression
The FLUX 3 Video Generator captures nuanced facial expressions, multilingual dialogue, and emotional subtlety that outperform competitor models in early benchmarks.
Self-Flow Architecture
Built on Black Forest Labs' Self-Flow approach, the FLUX 3 Video Generator aligns multimodal generation and understanding within a single underlying model.
Competitive Preference Scores
Preferred over Grok Imagine Video in 69%, Runway Gen-4.5 in 77%, and Luma Ray 3.2 in 93% of early comparisons — the FLUX 3 Video Generator leads while still improving.
Multilingual & Typography
Generate videos with accurate multilingual dialogue and strong typography rendering — the FLUX 3 Video Generator handles styles from candid camcorder to animation.
Open-Weight Backbone Planned
Black Forest Labs plans to release FLUX 3 Dev, an open-weight multimodal backbone, alongside API access for the FLUX 3 Video Generator.
FLUX 3 Video Generator — FAQ
Common questions about the FLUX 3 Video Generator and its multimodal video capabilities from Black Forest Labs.
What is the FLUX 3 Video Generator?
It is Black Forest Labs' multimodal foundation model that jointly learns from video, images, and audio. The FLUX 3 Video Generator produces 20-second audiovisual clips with native audio, superior human expressions, and five creative generation modes.
How is it different from other video models?
Unlike models trained on video alone, the FLUX 3 Video Generator learns cross-modal constraints — sound matches impact, motion obeys physics, and expressions stay consistent — because it trains on all modalities simultaneously via the Self-Flow approach.
What generation modes does it support?
The FLUX 3 Video Generator supports text-to-video, image-to-video (continuation or reference), video-to-video restyling, keyframe-to-video transitions, and generative audio-video continuation from input clips.
Does it generate audio?
Yes — every FLUX 3 Video Generator output comes with native synchronized audio including sound effects, dialogue, and ambient noise. No separate audio generation or post-production syncing required.
How long can videos be?
The FLUX 3 Video Generator produces clips up to 20 seconds in a single generation. Through reference-based agentic chaining, you can combine clips into multi-minute sequences with consistent characters.
Is FLUX 3 open source?
Black Forest Labs plans to release FLUX 3 Dev as an open-weight multimodal backbone. The FLUX 3 Video Generator is currently available through early access API and private weight access on bfl.ai.
