FLUX 3 Video Guide

FLUX 3 video generation with synchronized audio, text-to-video, image/keyframe control and video continuation; the related FLUX Video Edit tool handles source-preserving edits. This page connects the model data to working GenVideoKit prompt, image-to-video, comparison and cost tools.

Prompting strategy

Treat FLUX 3 video workflows as controlled transitions or source-preserving edits. For keyframes and first/last-frame generation, describe the motion path between anchors and explicitly lock identity, geometry and scene elements that must remain stable. For video editing, describe the requested delta from the source and state what must remain unchanged.

How to use FLUX 3 Video in a production workflow

Catalog checked 2026-09-20

Reference-led workflowsThis catalog entry includes reference-oriented controls. Use the source frame or reference asset to define appearance, then keep motion and camera instructions separate from identity constraints.

Audio-aware generationAudio is part of this model’s tracked workflow. Plan dialogue, ambience and action-linked sound as separate layers so timing remains readable.

Editing & continuationThe model supports a tracked editing or continuation workflow. Treat the source clip as the current state and describe only the intended change plus the elements that must remain stable.

Text-to-video baselineFor text-only generation, specify subject, one dominant action, camera behavior, environment and final composition before adding style language.

Questions to answer before choosing the model

Does the workflow require a reference image, first/last frame, keyframes or video input?
Is synchronized audio or lip sync a hard requirement, or can sound be added in post?
How many retries can the project budget tolerate before the cost advantage disappears?
Will the final delivery need several aspect ratios or should composition be generated natively for each format?
