Why Choose FLUX 3
FLUX 3 is Black Forest Labs' frontier multimodal model. It is trained across video, images and audio together, so each clip is generated with its soundtrack in the same pass instead of being dubbed afterwards. That keeps speech, effects and ambience aligned with what happens on screen.
It supports text-to-video for a scene described in words, and image-to-video when you want a still to open the clip and move. Clips run from 5 to 20 seconds at 720p or 1080p, and you can turn audio off when you only need picture.

FLUX 3 Features and Capabilities
Text to Video
Describe a scene in plain language and FLUX 3 turns it into motion, composition and sound. It follows detailed prompts while keeping the shot coherent.
Image to Video
Upload a starting image and let FLUX 3 animate it. Your frame opens the clip and the prompt describes how the scene unfolds from there.
Native Synchronized Audio
Video and audio are generated together, so ambience, effects and speech line up with the action. Turn audio off when you only need picture.
5 to 20 Second Clips
Choose a duration that fits your edit. Longer clips give a scene room to develop; shorter clips keep iteration fast and inexpensive.
720p and 1080p Output
Generate at 720p for quick drafts or at 1080p when the clip is going into a final cut. Pricing updates live as you change the settings.
Durable, Resumable Jobs
Every request is saved to your account. Finished videos are archived to the site’s storage, and progress resumes when you return.
