Flux 3 AI Video Generator

AI-suggested

Flux 3 AI Video Generator is a web-based creative tool that produces short AI-generated videos from text prompts, reference images, or reference videos. It offers three input modes - text to video, image to video, and video to video - and lets users choose aspect ratio, duration, and resolution before generating. The platform is aimed at creators who want to turn a scene idea into a motion sample quickly without needing traditional editing or filmmaking experience. The generator uses a single Flux 3 model, described as multimodal and trained on image, video, and audio together. This means generated clips can include native audio - such as footsteps, impacts, and ambience - timed to the visuals, rather than sound added in post-production. Flux 3 also supports expressive human motion, facial expressions, and multilingual dialogue, making it useful for character-driven story tests, brand assets, product demos, and social media clips. The workflow is built around prompting, previewing, and purchasing credits. Users write a prompt of up to 5000 characters, optionally add image or video references, generate a preview, and then use credits to render full videos. New users receive 100 free credits, and paid plans include Starter, Plus, and Pro tiers with monthly or yearly billing as well as one-time credit packs. The platform is positioned for individual creators, marketers, studios, and teams who need fast iteration for ads, storyboards, product videos, and short-form social content.
