FLUX 3 Max Video Generator

What you can do with FLUX 3 Max here

FLUX 3 Max is the fast, post-trained member of Black Forest Labs' FLUX 3 family for moving pictures. It generates sound along with the picture, so a clip arrives with its ambience and effects already in place.

• Text to video. Describe the shot, the movement, and what you want to hear. Without a frame, Auto renders 16:9.
• Start from your own image. Add a still as the start frame and describe how the scene moves from there. Auto keeps the image's own shape.
• Land on an end frame. Add a second image and the clip travels from the first frame to the last.
• Pick the length. Every whole second from 5 to 20.
• Sound on or off. Leave sound on for native audio, or switch it off for a silent clip. The price is the same either way.

Price per clip

Every run shows its price on the prompt box before you start. FLUX 3 Max is charged per second of video: 64 credits per second at 720p and 108 at 1080p. A start or end frame, the aspect ratio, and sound do not change the price.

Credits come with a Lite, Pro, or Ultra plan or a one-time pack; see the pricing page. If a run fails, its credits come back automatically.

How fast is FLUX 3 Max?

Black Forest Labs' own figures for Max: a 10-second clip in about 12 seconds, and 22× faster than Seedance 2.5 at the same quality. Those are the maker's numbers; we have not timed it ourselves yet. Here a run first rewrites your prompt into a detailed shot description, then renders, uploads, and saves, so expect the clip in your history a little after that.

How to use FLUX 3 Max

1. Sign in with Google.
2. Check that the model on the prompt box says FLUX 3 Max.
3. Write the shot: subject, action, camera, light, and sound. Optionally add a start frame, then an end frame.
4. Open the settings pill to pick aspect ratio, 720p or 1080p, and a length from 5 to 20 seconds. The credit price updates as you go.
5. Run it. The clip plays in your history, ready to download.

Prompt tips for FLUX 3 Max

• Write the movement, not only the picture. Say what happens first and what happens next: "pauses, sniffs the air, then climbs over the branch."
• Name the camera. Slow push-in, handheld follow, locked-off wide, drone pull-back.
• Ask for the sound you want. Birdsong, rain on glass, a crowd murmuring, traffic in the distance.
• With a start frame, describe the change. The image already sets the look; spend the prompt on motion and sound.
• Start at 720p and 5 seconds. Find the shot cheaply, then render the keeper at 1080p or longer.
