# FLUX 3 Video - AI video generation with native audio

> Generate videos with synchronized audio using FLUX 3 in ComfyUI, from text or images, with up to 20 seconds of footage in a single pass

FLUX 3 is Black Forest Labs' multimodal foundation model, announced July 23, 2026 and currently in Early Access. It jointly learns from images, videos, and audio within a unified architecture built on Self-Flow, their approach for aligning multimodal generation and understanding in the same model. Instead of treating each modality in isolation, FLUX 3 learns a shared representation of the world: how objects hold together, how things move, and how events sound. Capabilities and limits may change during the Early Access rollout.

For video, FLUX 3 creates highly diverse clips with native audio up to 20 seconds long in a single generation. All outputs come with synchronized audio generation, including ambient sound, speech, and effects. It supports text-to-video and image-to-video generation, with multi-shot output that chains individual clips into longer sequences and flexible aspect ratios.

      Workflows in this guide can be found in the [Workflow Templates](/interface/features/template).
      If you can't find them in the template, your ComfyUI may be outdated.

      If nodes are missing when loading a workflow, possible reasons:

      1. You are not using the latest ComfyUI version (Nightly version)
      2. Some nodes failed to import at startup

      * [Cloud](https://cloud.comfy.org) will update after ComfyUI stable release.

      So, if you find any core node missing in this document, it might be because the new core nodes have not yet been released in the latest stable version. Please wait for the next stable release.
