Key capabilities

Why creators pick FLUX 3

Generate picture and sound together

Describe the action, camera movement, dialogue, ambience, and effects in one prompt. FLUX 3 composes the moving image and synchronized soundtrack in the same generation.

“A home video of a futuristic San Francisco with people riding hoverboards.”

Keep motion coherent across the shot

Build atmospheric scenes with grounded camera movement, subject motion, and environmental detail across clips from 5 to 20 seconds.

Storyboard or continue an existing shot

Use one image as the opening frame, two as start and end frames, up to ten as a timed storyboard, or an MP4 as the starting point for a continuation.

How to get a strong result

Tips for better results

Start with the subject, then add lighting, style, and anything that must stay the same. Upload a reference whenever you want a more controlled edit.

1
Write sound into the prompt
Name dialogue, room tone, music, and effects explicitly when audio matters.
2
Set duration for 3+ images
Storyboard inputs require an explicit duration so frames can be distributed predictably.
3
Draft before 1080p
Validate timing and composition using Draft, then render the final clip at full quality.
