# 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.

## What FLUX 3 Video is good at

* **Native audio**: Every video comes with synchronized audio, including ambient sound, speech, and effects
* **Up to 20 seconds**: Generates long clips in a single pass
* **Text and image input**: Generates video from a text prompt, or continues from a starting frame image
* **Flexible formats**: 720p or 1080p resolution, 24fps, aspect ratios from 9:16 to 21:9
* **Multi-shot output**: Chains individual clips into longer sequences for extended storytelling

## Example outputs

Text-to-video generation from a single prompt, with synchronized audio, motion, and physics:

<video controls className="w-full aspect-video" src="https://raw.githubusercontent.com/Comfy-Org/workflow_templates/main/output/api_bfl_flux3_t2v.mp4" />

Image-to-video generation from a starting frame and a text prompt:

<video controls className="w-full aspect-video" src="https://raw.githubusercontent.com/Comfy-Org/workflow_templates/main/output/api_bfl_flux3_i2v.mp4" />

## Use it in ComfyUI
