Pick up where it stops

Ballerina dancing against grey plaster

Continues from the final frame

Give FLUX.3 Extend a finished video and describe what happens next. It starts from the clip's last frame, so the subject, the setting and the light carry on without a visible join.

5 to 20 seconds at a time

Choose how much to add, one second at a time. Short extensions let a scene breathe or land an ending; longer ones turn a moment into a full scene.

720p or 1080p, with sound

Extend at 720p or 1080p. Audio can be on or off at the same price, so the continuation can carry the ambience of the original clip.

FLUX.3 Extend

Video in. 5 to 20 more seconds. 720p or 1080p. Audio.

When to extend

  • Ballerina dancing against grey plaster

    Endings. A clip that stops too soon gets the last beat it was missing: a final pose, a look to camera, a fade into the logo.

  • Fisherman hauls nets in a seaside village

    Longer scenes. Join extensions to grow a short moment into a scene longer than a single generation allows.

  • Damascus knife slicing marbled wagyu

    Product moments. Let a product shot keep rolling after the reveal, so there is room for a voice-over or a caption.

FLUX.3 Extend questions

What is FLUX.3 Extend?

FLUX.3 Extend is the extend mode of Black Forest Labs' FLUX.3 video model. It continues an existing clip beyond its final frame by 5 to 20 seconds, at 720p or 1080p.

How much does FLUX.3 Extend cost?

157 credits per second at 720p and 179 at 1080p, with or without sound. A 5 second 720p extension is 785 credits; a 20 second 1080p extension is 3,580 credits.

How much can I add to a clip?

Between 5 and 20 seconds per extension, in whole seconds.

When should I use Extend instead of a new FLUX.3 generation?

Use Extend when the new part has to continue the same shot with no cut: the same subject, framing and light. It costs more per second than a fresh FLUX.3 clip (65 or 98 credits), so for a new angle or a new scene, generate a new clip instead.

Does FLUX.3 Extend generate audio?

Yes, audio can be on or off, and the price is the same either way.

How do I get a smooth continuation?

Describe the next beat in the same terms as the original clip: the same subject, the same setting, one action and one camera move. Avoid asking for a sudden change of location or style in the extension.

Can I try FLUX.3 Extend for free?

Your first image is free after you sign up, no card needed. Video models, including FLUX.3 Extend, need a plan or a one-time credit pack. Credits never expire.

Don't cut. Continue.
