FLUX 3 Video is Black Forest Labs' video-generation and editing offering. The developer's product page describes one multimodal model spanning images, video, audio and action prediction.
Control a scene with prompts and frames
The FLUX 3 Video page lists text-to-video, image-to-video and video editing. It also describes ordered keyframes: you can specify a start frame, an end frame or several keyframes in sequence. These inputs give you a way to define the intended composition and progression before judging a generated clip.
Black Forest Labs says the model can edit an existing clip from a text instruction while retaining the unmentioned material. Its examples also cover multiple scenes, multilingual dialogue and typography within a scene. Those are developer claims about the supported tasks; precise preservation of faces, objects or text still needs inspection in the result.
Preview a direction before a full render
The developer describes draft mode as a lower-cost preview that can be submitted again for a full-quality render. That distinction is useful when deciding whether a camera move or visual style warrants a more expensive generation. Evaluate the preview against your brief, then check the finished render rather than assuming the two quality levels look identical.
Clip continuation starts from the final frame of an existing video, according to the product page. Agentic chaining is also listed for joining clips into a longer story. These capabilities relate to the Self-Flow architecture described in Franklin's coverage of the multimodal model: Black Forest Labs says the underlying approach aligns generation and understanding across modalities. That architectural description does not establish a particular output's accuracy.
Read the selected pricing settings
The developer's pricing page describes pay-as-you-go access without subscriptions or seat fees. Its displayed calculator example charges $0.85 for five seconds at $0.17 per second. Read that as an example tied to the selected mode and settings, not a universal rate for every resolution or editing task.
The page separates generation pricing from open-weights licensing. Check the applicable access and usage terms before building a production workflow; a model family's licensing options do not imply that every listed model or output has the same rights.
