FLUX.3 AI Video Generator
Create a new FLUX.3 scene or switch its workflow to continue an existing video. Start with the prompt tool and choose the clip settings above.
Start image
Create from a prompt alone or add an opening image.
Enter at least 3 characters to continue.
What you can create with FLUX.3
FLUX.3 exposes separate text, frame-based and video-extension workflows. Use extension when you already have footage to continue, rather than supplying a new first-frame image.
When to use this tool
Use FLUX.3 to set up a 5–20 second clip from a prompt or first frame, then use its extension workflow when the next shot should continue existing footage.
This video tool offers 720P and 1080P, with a separate source-video input for extension. For a still image use FLUX.2 Flex, and for changing the person without changing the original sequence use MiniMax H3 Recast.
A prompt to adapt
A cyclist emerges from a tunnel into a sunlit coastal road, tracking camera, sea breeze and bicycle sounds.

How are generation credits calculated?
Credits depend on the selected model, duration, resolution and input materials. Review the current estimate before submitting. Agent projects may include several generation tasks, each with its own credit usage. FLUX.3 generation and extension are quoted by the requested output duration. Check the quote again after changing the clip length.
Where can I find and download my results?
Completed results are available in your workspace. Open the task to preview or download its files. For an Agent project, review the storyboard and the assembled video in the project.
