What Makes the FLUX.3 Video Generator Stand Out
Black Forest Labs' latest multimodal foundation model trains on video, images, and audio together inside one unified system. Announced in July 2026, it generates 20-second audiovisual clips, captures subtle human facial movements, and earns top preference scores against competing video models — all powered by the Self-Flow training method.
- Unified Cross-Modal LearningBy simultaneously training on video, images, and audio, the FLUX.3 Video Generator learns the natural relationships between motion, visuals, and sound as they occur in the real world.
- Built-In 20-Second AudioEach output from the FLUX.3 Video Generator includes synchronized sound — dialogue, sound effects, and ambient audio generated at the same time as the visuals.
- Intelligent Multi-Shot SequencingLink individual clips into longer narratives with consistent character appearances across scenes using the reference-based chaining capability of the FLUX.3 Video Generator.
Getting Started with the FLUX.3 Video Generator
Produce multimodal videos with built-in audio across five creation modes using the FLUX.3 Video Generator.
Key Capabilities of the FLUX.3 Video Generator
A single model that handles text-to-video, image-to-video, video-to-video, keyframe transitions, and agentic multi-shot chaining — the FLUX.3 Video Generator already beats top competitors in early preference tests and continues to improve.
Five Creation Modes
Text-to-video, image-to-video continuation, video-to-video restyling, keyframe-based transitions, and audio-video extension — all inside the FLUX.3 Video Generator.
Expressive Human Detail
The FLUX.3 Video Generator excels at capturing subtle facial expressions, multilingual speech, and emotional nuance, outscoring rival models in early evaluations.
Self-Flow Architecture
Built on the Self-Flow framework from Black Forest Labs, the FLUX.3 Video Generator aligns multimodal generation with understanding inside one unified model.
Leading Preference Scores
In early blind comparisons, the FLUX.3 Video Generator is preferred over Grok Imagine Video by 69%, Runway Gen-4.5 by 77%, and Luma Ray 3.2 by 93% — and the model is still being refined.
Multilingual Dialogue & Typography
Generate videos with accurate multilingual speech and strong text rendering — the FLUX.3 Video Generator handles styles from raw camcorder footage to cartoon animation.
Planned Open-Weight Release
Black Forest Labs intends to release FLUX 3 Dev, an open-weight multimodal backbone, together with API access for the FLUX.3 Video Generator.
Frequently Asked Questions — FLUX.3 Video Generator
Answers to common queries about the FLUX.3 Video Generator and its multimodal video capabilities from Black Forest Labs.
What exactly is the FLUX.3 Video Generator?
It is a multimodal foundation model by Black Forest Labs that learns from video, images, and audio simultaneously. The FLUX.3 Video Generator creates 20-second audiovisual clips with native sound, realistic human expressions, and five creative generation modes.
How does it differ from other video models?
Unlike models that train only on video, the FLUX.3 Video Generator learns across all modalities — sound matches movement, physics governs motion, and expressions stay natural — because it trains on video, images, and audio together through the Self-Flow method.
Which generation modes are supported?
The FLUX.3 Video Generator supports text-to-video, image-to-video (continuation or reference), video-to-video restyling, keyframe-based transitions, and generative audio-video continuation from existing clips.
Does the output include audio?
Yes — every clip from the FLUX.3 Video Generator comes with native synchronized audio including sound effects, dialogue, and ambient sounds. No extra audio generation or post-production syncing is needed.
What is the maximum video length?
The FLUX.3 Video Generator produces clips up to 20 seconds in one generation. By using reference-based agentic chaining, you can connect clips into multi-minute sequences with consistent character appearances.
Will FLUX 3 be 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 at bfl.ai.
