Flux 3 Key Features
Text, Image & Keyframe to Video
Turn a prompt, a still image, or a keyframe into flux video up to 20 seconds long. Flux 3 handles camera motion, lighting, and physics automatically — describe the shot and it directs it.
Native Audio, In Sync
Flux 3 generates sound as a first-class signal, not an afterthought. Dialogue, sound effects, music, and ambience are timed to on-screen events, so a closing door or a footstep lands exactly when it should.
Photoreal Images & Razor-Sharp Text
The same model renders flux image stills across a huge range of styles — from candid camcorder footage to polished cinematics — with high-accuracy typography in multiple languages.
Multilingual Dialogue & Consistent Characters
Give a character lines in multiple languages and Flux 3 speaks them with matching motion. Reference images keep the same character and style consistent as you chain clips into longer scenes.
Move Fluidly Between Formats
Start from text, promote a still to motion, or continue an existing clip. Flux 3 lets you flow between flux image, flux video, and audio in one workflow instead of exporting between separate tools.
How to Use Flux 3 Online
Go from a prompt to a Flux 3 video with sound in three simple steps.
Step 1 — Describe Your Shot or Upload a Reference
Tell Flux 3 what you want — subject, action, mood, camera. Or upload a reference image or keyframe to guide the look, the character, or the starting frame of your flux video.
Step 2 — Pick Image or Video, Then Generate
Choose a still flux image or a video up to 20 seconds with native audio. Set aspect ratio and style, hit generate, and Flux 3 handles cameras, lighting, and sound for you.
Step 3 — Refine, Continue, and Download
Extend the clip, swap the audio, or chain another shot while keeping your character consistent. When it's ready, download your Flux 3 result in high quality for immediate use.
Use cases
Flux 3 Use Cases — Who Is It For?
Flux 3 is built for creators and teams who need image, video, and audio to come out of one model, in sync and on brand.
Content Creators & Social Media
Turn a prompt into scroll-stopping flux video with native audio, or a flux image thumbnail, in minutes. Keep a recurring character consistent across posts and chain 20-second clips into longer stories — no separate editing suite required.
Marketing Teams & E-Commerce
Produce product videos, ad spots, and campaign stills from one model. Flux 3 renders accurate on-pack text, consistent lighting, and spoken multilingual voiceover, so you can localize a spot without a studio shoot.
Filmmakers & Studios
Previz a scene, generate a keyframe, then animate it into a 20-second flux video with matched sound design. Flux 3's Self-Flow backbone keeps motion physically plausible and characters on-model across shots.
Developers & API Integration
Build Flux 3 image and video generation into your own apps and pipelines through the provider API. This site is an independent web interface for Flux 3 and does not resell raw API access.
What Is Flux 3? Black Forest Labs' Unified Real World Model
Flux 3 is Black Forest Labs' next-generation multimodal model. Instead of separate tools for image, video, and sound, Flux 3 learns them together in one Self-Flow backbone — so a still flux image, a 20-second flux video, and its native audio all come from the same model, natively in sync.
Type a scene and Flux 3 renders it as an image or animates it into flux video with dialogue, sound effects, and music. Start from text, a reference image, or a keyframe, keep characters consistent across shots, and chain clips into longer sequences.

Flux 3 leads on unified image-plus-video generation and native, physically-aligned audio from a single model. In Black Forest Labs' early preference tests, Flux 3 was preferred over Runway Gen-4.5 and Luma Ray 3.2 by wide margins and over Kling v3 Pro in a majority of comparisons. Kling excels at human motion and Runway at post-production control, but for one model that outputs flux image, flux video, and sound together, Flux 3 is the strongest choice.
