FLUX.3 Video

Getting started

The featured Edit Video operation starts from footage you already have. Use it to try a change in the scene, such as snowy weather or a different color treatment, while asking to retain the original action and framing. Begin with one clear change so that you can compare the result with the source. The example below needs an uploaded video; it cannot create a clip from text alone.

Example prompt

Add falling snow and a cold winter color palette to this street scene. Keep the same camera movement, walking direction and framing. Preserve the clothing and appearance of the people.

Review your result

Compare the beginning, middle and ending with the original clip. Check faces, clothing, motion, timing and whether the requested change flickers between frames. Listen to the output before using it; do not assume the source soundtrack has been preserved.

Inputs and settings

Edit Video requires video_url and prompt. Upload an MP4 smaller than 50 MB and shorter than 15 seconds. The editing instruction accepts up to 4,096 characters.

This editing operation does not expose duration, resolution, seed or keyframes as input controls. Settings from another FLUX.3 operation cannot be copied into this request.

Choose Text to Video for a new scene, Extend Video to continue footage, First/Last Frame for a transition between two images, or Keyframes for multiple reference frames. Each is a separate operation with its own required inputs and quote; their schemas are listed below.
