FLUX 3 Video

FLUX 3 Video is a browser-based AI tool that turns written scene descriptions into short video clips. You type a prompt — something like "Golden-hour drone shot over a misty mountain valley, slow push-in, anamorphic flare" — pick a duration (5, 8, or 10 seconds), choose an aspect ratio (16:9, 9:16, 1:1, or adaptive), select a resolution (480p or 720p), and decide whether to include audio. Optionally upload a reference image (JPEG, PNG, WebP, or GIF, up to 4MB) to anchor the visual style or subject. There is no timeline editor, no keyframes, no export queue.

The tool works asynchronously: after you submit the request, the server processes it in the background while the page automatically checks the status. When the render is ready, you can preview or download the clip. The main capabilities are text-to-video generation, reference image input, flexible aspect ratios, configurable duration and resolution, optional audio generation, and background processing. The interface is minimal — just a prompt box, some dropdowns, a toggle for audio, and a generate button.

This tool is best for content creators, social media marketers, or anyone who needs short video clips quickly without editing software. Real-world use cases include making atmospheric B-roll for a vlog, prototyping a visual idea before a full production, or generating social media posts in 9:16 format. It is not designed for long-form video or complex edits, but for turning a prompt into a short clip with minimal friction.
