FLUX 3 Video Editing Guide

Write targeted FLUX 3 video-edit instructions that change one element while preserving source motion, timing and framing.

How this workflow works

FLUX 3 video editing is source-preserving: it can re-render a supplied clip from a natural-language instruction while retaining motion, timing and framing. The safest edit prompts clearly separate the requested change from everything that should remain untouched.

Step 1

Name the exact edit

Ask for one bounded change such as weather, color palette, background treatment or object appearance.

Step 2

State preservation constraints

Explicitly preserve camera motion, timing, subject identity, body motion, composition and other elements that should not change.

Step 3

Avoid rewriting the whole scene

A full generative description can cause unnecessary drift. Describe the delta from the source video instead.

Prompt example

A practical starting structure

Change only the weather to heavy snowfall and shift the environment toward a cold winter palette. Preserve the original person, facial identity, clothing, body motion, camera movement, framing, timing and scene layout. Do not add or remove objects.
