FLUX.3 Video

byBlack Forest Labs

Long takes that hold their subjects, weight and sound together, from a prompt, a start frame, two keyframes or a clip you want to carry on

How FLUX.3 Video works

Brief it like a cinematographer, sketch the take cheaply in Draft, then spend the budget once on the render that matters.

opening frame

Brief the shot

Write the camera move, the subject's action and the sounds you want, or drop in a start image, an end image or a clip to extend.

scene and camera direction

Draft it cheap

Set 5 to 20 seconds and your aspect ratio, then switch Draft on to lock camera, timing and audio at 720p.

Render the final take

Turn Draft off, choose 1080p and run the take with picture and sound generated together.

What FLUX.3 Video is good at

Built for shots that need to last: stable subjects, believable physics, and sound that lands on the beat.

Picture and sound in one pass

Impacts, room tone and lip-synced speech track what happens on screen, in clips of 5 to 20 seconds. Describe the sounds in your prompt, or the model invents audio from context.

Two-frame transformations

The first-last-frame variant bridges a start and end image for makeovers, day-to-night and scene morphs. Keep both frames related in subject and lighting, and prompt the bridge itself.

Extend a clip you like

Extend mode continues an existing shot from its final moment, keeping style and subject consistent. It is the costliest mode, so preview the next beat with the Draft variant first.

Draft before you commit

Draft fixes the render at 720p and costs a fraction of standard, about 413 to 1653 against 1171 to 7990. Settle camera, timing and audio, then re-run at 1080p.

What people build with FLUX.3 Video

For directors, brand teams, fashion labels and social creators who need a shot that plays out rather than a looping flourish.

Film previs and shot tests

01

Directors and cinematographers block multi-beat takes of up to 20 seconds, with dialogue and ambient sound, to test camera move and tone before a shoot.

Fashion lookbook motion

02

Labels and agencies turn a lookbook still into a moving frame with the start-image mode, so cloth weight and swish carry the garment.

Product and hardware commercials

03

Brands animate an approved product still while keeping its design intact, or morph one finish into another with a start and end frame.

Vertical social moments

04

Content teams set 9:16, draft cheap versions of a hook, then re-run the keeper at 1080p with sound already matched.

Album art in motion

05

Musicians and designers bring a sleeve or poster to life, bridging two key images with a prompted transition and a sound bed that fits.

FLUX.3 Video questions

Draft is a faster, cheaper 720p render for iterating, while standard runs at 720p or 1080p for final quality. Draft costs about 413 to 1653 against 1171 to 7990 for standard text, image and two-frame modes. Draft is visibly softer, so use it to settle camera move, timing and audio, not to judge fine detail.

Use image-to-video to animate one approved still while keeping its design intact; describe the motion and camera, not the image. Use first-last-frame to bridge two prepared frames, such as day-to-night or a product makeover. Mismatched frames produce odd morphs, so keep subject and lighting related.

Extend mode continues an existing clip from its final moment, following your prompt. It is the most expensive mode, about 2824 to 14603 (827 to 3306 as a draft). Check the source clip's last frames first and preview with the draft variant.

Yes. Audio is generated alongside the picture and is on by default, covering ambient sound, impacts and lip-synced speech. Describe the sounds you want in the prompt, since unspecified audio can be invented from context. Turn Generate Audio off if you'll score the clip elsewhere.

It is a poor fit for silent short loops at the lowest cost, exact typography or logo animation, and frame-accurate control. Small on-screen text can be unreliable, and very long clips with many beats can drift. Avoid 1080p renders for early ideation.

FLUX.3 comes from Black Forest Labs. Release dates in the research run from 23 July 2026 to 4 August 2026, reported from summaries rather than a primary page. Clips run 5 to 20 seconds at 720p or 1080p.
