FLUX.3 Video Generator — Your Questions Answered
Quick answers about Black Forest Labs' multimodal video tool, the FLUX.3 Video Generator, covering capabilities, modes, audio, and availability.
What does the FLUX.3 Video Generator do?
It is Black Forest Labs' multimodal foundation model that learns from video, stills, and audio together. The FLUX.3 Video Generator creates 20-second audiovisual clips with native sound, realistic human expressions, and supports five distinct generation modes.
How does it differ from conventional video generators?
Unlike single-modality models, the FLUX.3 Video Generator learns cross-modal relationships—sound matches motion, physics governs movement, and expressions stay consistent—thanks to joint training through the Self-Flow approach.
Which generation modes does it offer?
The FLUX.3 Video Generator provides text-to-video, image-to-video (continuation or reference), video-to-video restyling, keyframe-to-video transitions, and generative audio-video extension from input clips.
Does it produce audio automatically?
Yes—every output from the FLUX.3 Video Generator includes native synchronized audio, covering sound effects, dialogue, and ambient noise. No separate audio generation or manual sync is needed.
How long can the generated videos be?
Each generation from the FLUX.3 Video Generator lasts up to 20 seconds. By chaining clips using reference-based agentic generation, you can build multi-minute stories with consistent characters.
Is FLUX.3 open-source?
Black Forest Labs intends to release FLUX 3 Dev as an open-weight multimodal backbone. Currently, the FLUX.3 Video Generator is available via early access API and private weights on bfl.ai.
