What This App Does

FLUX 3 Max is the top video model of Black Forest Labs, the team behind the FLUX image models. Describe a scene in plain language and it produces a clip with motion, camera work and a synchronized soundtrack: ambience, effects and speech, generated together with the picture rather than added afterwards. Before generating, the model reasons about your prompt and expands it, so short descriptions still give a complete shot.

Key capabilities

  • Text to video — turn a written description into a finished clip

  • Native audio — ambience, sound effects and dialogue generated in sync with the image, or a silent clip if you turn it off

  • Clips from 5 to 20 seconds, long enough for a full shot

  • Two output resolutions — 720p, and 1080p for final delivery

  • Framing — auto picks a ratio from the prompt, or choose 21:9, 2:1, 16:9, 4:3, 1:1, 3:4 or 9:16

  • Prompt reasoning — high (default) for the best result, low to go faster

  • Image to video is available on the same node — switch its mode to animate a first image, optionally up to a last one

Core inputs

  • prompt (text, required) — the scene, the action, the camera movement and the sound you want

  • duration — 5 to 20 seconds (default 5)

  • resolution — 720p (default) or 1080p

  • aspect_ratio — auto (default), 21:9, 2:1, 16:9, 4:3, 1:1, 3:4 or 9:16

  • generate_audio — on by default

  • reasoning_level (advanced) — high (default) or low

  • seed (advanced, optional) — reuse it to reproduce a result

The cost depends on the duration and the resolution. To iterate on an idea cheaply before a full render, the FLUX 3 draft to final template makes fast 720p drafts and renders the one you keep.

Golden hour on a rocky coastline: waves crash against a red-and-white lighthouse while seagulls wheel overhead. Slow aerial orbit around the lighthouse, sea spray catching the warm light. We hear crashing surf, gusting wind and distant gull cries.

Frequently Asked Questions

Do I need a subscription to use FLUX 3 Max?

No. Buy a credit pack once, generate, and come back whenever you want. Purchased credits stay valid 12 months, and every new purchase extends them.

What is FLUX 3 Max?

FLUX 3 Max is Black Forest Labs’ most capable video model. It turns a text prompt into a video clip with motion, camera movement and a synchronized audio track.

Does it generate sound?

Yes. Audio is on by default: ambience, effects and speech are generated together with the picture. Turn generate_audio off for a silent clip.

How long can the videos be?

Any whole number of seconds from 5 to 20. The default is 5 seconds.

Which resolutions are available?

720p and 1080p. 720p is the default; 1080p costs more per second.

Can I choose the format of the video?

Yes: 21:9, 2:1, 16:9, 4:3, 1:1, 3:4 or 9:16. With auto, the model picks a ratio that fits the prompt.

Can I animate my own image?

Yes. Switch the node to Image to Video: your image becomes the first frame, and you can add an optional last frame.

What does the reasoning level change?

The model rewrites and expands your prompt before generating. High, the default, gives the best results; low is faster.

What drives the price?

The duration and the resolution: you pay per second of video, more in 1080p than in 720p.

How should I write the prompt?

Describe the scene, who or what is in it, what happens, how the camera moves and what we should hear. Plain sentences work best.

How is it different from FLUX 3?

Max is the higher-quality model. FLUX 3 adds a cheap draft mode, 2K and 4K output and clip extension; use it to explore ideas before a final render.

How do I know what a generation will cost?

The app shows the exact price on the Generate button and updates it as you change the settings, before anything is billed.

Is there a free trial available?

Yes, AI-FLOW offers a free trial to get you started. After that, you can purchase credits as needed—no subscription or long-term commitment required.
