Omni Flash

Omni Flash is a free online AI video generator that enables users to create cinematic 4K video content from text prompts, static images, or existing video clips. The platform integrates native audio syncing, including lip-sync capabilities, and maintains consistent character appearances across generated scenes — a feature that distinguishes it from many other AI video models. Users can input a text description of a scene, upload a reference image (up to 9 images per generation), or remix an existing clip to produce a high-resolution 1080p or 4K video in approximately 60 seconds. The system is built around a dedicated video model called "Omni Flash Recommended," which supports up to 15 seconds of video output per generation, with native audio embedded directly into the output — no separate audio track alignment is required. The platform also offers an image generation mode alongside the video mode, allowing users to create static visuals as well. The core functionality revolves around three primary input methods: text-to-video, image-to-video, and clip-to-video. For text-to-video, users write a prompt (up to 2000 characters) describing the desired action, environment, lighting, camera movement, or artistic style. The AI then interprets the prompt and renders a video that matches the description. For image-to-video, users upload one or more reference images to guide the model's understanding of characters, objects, or settings — the model will preserve the visual details (such as clothing, facial features, or background elements) across frames, enabling consistent storytelling. For clip-to-video, users can upload a short video segment and ask the model to extend, reimagine, or modify it, effectively acting as a video editing and remixing tool. A key technical capability i
