FLUX 3 AI Video Generator: Create Cinematic Videos with Native Audio
Generate cinematic AI videos with native audio using FLUX 3, Black Forest Labs' multimodal foundation model for video, audio, images, and action-aware generation. Create up to 20-second clips from text prompts, images, keyframes, or video references on Medeo, then refine your idea into a polished video workflow.
What Is FLUX 3?
FLUX 3 is Black Forest Labs' multimodal foundation model for generating and understanding video, audio, images, and actions within one unified architecture. FLUX 3 Video focuses on cinematic video generation with native audio, supporting text-to-video, image-to-video, video-to-video, video continuation, and controlled transitions with keyframes. With Medeo, creators can use FLUX 3 to create short audiovisual clips, product scenes, social videos, cinematic stories, and reference-guided video outputs without managing complex model setup.
A Multimodal Model for Video and Audio
FLUX 3 is built to connect video, audio, images, and action understanding in one model family. Instead of generating silent clips first and adding sound later, FLUX 3 can create native audio alongside the video, helping creators build more complete short-form content from the first generation.
Create Up to 20-Second AI Videos
FLUX 3 Video can generate clips up to 20 seconds long, giving creators more room for complete scenes, product moments, dialogue beats, camera movement, and visual storytelling than shorter AI video generations.
Core Capabilities of FLUX 3 AI Video Generator
FLUX 3 is designed for creators who need more than a basic prompt-to-video tool. It supports cinematic generation, native sound, image references, keyframe control, video continuation, and multimodal creative direction.
Text-to-Video with Cinematic Prompt Control
Describe a scene, subject, action, camera movement, lighting style, visual mood, and sound direction. FLUX 3 turns written ideas into cinematic AI videos with stronger audiovisual coherence and more room for scene development.
Image-to-Video and Reference-Guided Creation
Upload an image to guide the character, product, setting, or visual style. FLUX 3 can animate still images into moving videos while preserving important visual details and adding camera movement, ambience, and native audio.
Keyframes and Controlled Transitions
Use keyframes or visual references to guide how a shot changes over time. This makes FLUX 3 useful for creators who want more control over motion, scene progression, character placement, product reveals, or first-to-last-frame transitions.
Native Audio, Ambience, and Sound Direction
FLUX 3 can generate video and audio together, including ambience, sound effects, music mood, and speech direction depending on the workflow. This helps creators produce more complete audiovisual clips without treating sound as an afterthought.
Video-to-Video and Clip Continuation
FLUX 3 supports workflows that use existing video as a reference or extend a clip beyond its final frame. This is useful for continuing motion, expanding a scene, refining a short clip, or building a longer story from multiple connected generations.
How to Use FLUX 3 on Medeo
FLUX 3 works best when you provide a clear creative brief. Start with text, images, keyframes, or video references, describe the motion and sound, then generate and refine your video inside Medeo.
Step 1
Start with a Prompt or Reference
Enter a text prompt, upload an image, add keyframes, or use a video reference to guide the scene, subject, style, and motion you want FLUX 3 to create.
Step 2
Describe Motion, Camera, and Audio
Add details about the action, camera movement, lighting, pacing, ambience, sound effects, voice direction, or music mood so FLUX 3 can generate a more complete audiovisual result.
Step 3
Generate Your FLUX 3 Video
Select FLUX 3 in Medeo and generate your AI video. Review the motion, sound, scene consistency, subject detail, and overall pacing before choosing the best result.
Step 4
Refine, Extend, or Compare Models
Use follow-up instructions to improve the clip, continue a video, adjust the prompt, or compare FLUX 3 with other AI video models available in Medeo.
What You Can Create with FLUX 3
Use FLUX 3 for cinematic clips, product videos, social media content, AI ads, story scenes, music-driven visuals, and reference-based video generation.
Cinematic Short Scenes
Create atmospheric scenes with camera movement, lighting, sound, and visual rhythm. FLUX 3 is useful for short film concepts, mood videos, dramatic clips, fantasy scenes, and cinematic social content.
Product Reveals and Marketing Videos
Turn product images, campaign ideas, or brand prompts into short videos with movement, sound, and premium visual treatment. Use FLUX 3 to test product ad concepts before investing in full production.
Social Videos for TikTok, Reels, and Shorts
Generate short audiovisual clips for social platforms with stronger hooks, native sound, and platform-ready pacing. FLUX 3 is useful for creators who need videos that feel complete in a short format.
Music Visuals and Audio-Led Clips
Create visuals where audio is part of the idea from the beginning. FLUX 3 can support videos with ambience, sound design, musical mood, or dialogue direction, making it suitable for music-led social clips and creative campaigns.
