FLUX 3 Video

Video from words or from your frames, a clip changed by your words, and a clip continued — up to 4K, with its own sound if you want it.

FLUX 3 Video is a video model that works four ways: from your words alone, from a picture of yours as the first frame (and a second one as the last frame if you like), on a clip you already have, changing what your words say, and on a clip you want to go on for a few more seconds. When Studio offers it, you find it under Videos on Studio's home and Generation in Choose a model.

The price is never written here — prices change. It is on the model's page in Studio: on the Make button and beside each length, size or quality that changes it, before you press.

Writing for it

Say what happens, in order, the way you would describe one unbroken shot. Choose a Length first — every whole second in its range.

Shape has an Auto choice: from words the model picks the shape; from a picture it keeps the picture's own.

With a last frame the video is made between your two pictures, at 720p or 1080p.

Edit keeps your clip's motion, timing and framing and changes what you describe — "make it snow", "turn the car red". Extend carries on from your clip's last moments: say what happens next, and choose how many new seconds. Both take a short clip; the table above says how long.

Turn Sound on for a take with its own sound.
