FLUX 3 Max is a video model in the FLUX 3 family from Black Forest Labs, tuned for speed and for following the prompt closely. It makes 5 to 20 second clips at 720p or 1080p, from text alone or from one or two images, and writes a soundtrack that matches the scene. Flux3Max runs it in your browser: no install and no API key, paid per second with credits.
Describe the scene, the subject, the camera move and the sound. The model writes the shot from scratch. With Auto, the frame is 16:9.
Upload a picture and describe the motion. The picture becomes the first frame, so faces, products and layouts stay as they are.
Upload where the video starts and where it ends. The model builds the motion in between: transitions, reveals and before-and-after shots.
Pick a mode, describe what should happen, and add one or two frames if you want to start from an image.
Any length from 5 to 20 seconds, 720p or 1080p, an aspect ratio from 21:9 to 9:16, with or without generated audio. The price updates as you choose.
Credits are held, FLUX 3 Max renders the clip, and the MP4 appears next to the editor and in My videos. You pay only when it is delivered.
