Gemini Omni Flash: Google's Full-Modality AI Video Generator

Create and iteratively edit videos with Google's most advanced multimodal AI model. Gemini Omni, part of the Gemini 3.5 series (May 2026), replaces Veo 3.1 with a unified model that natively handles text, image, video, and audio. Its breakthrough feature is multi-turn conversational editing — refine scenes, swap characters, transfer styles, and add effects through natural language without regenerating from scratch. Powered by deep world knowledge and real-world physics simulation, Gemini Omni produces videos with realistic gravity, fluid dynamics, and material interactions. It also generates synchronized audio — sound effects, ambient audio, and music — directly alongside video output. Available on SJinn with no waitlist.

Step 1: Upload References & Describe Your Vision

Upload up to 7 reference images or a 10-second reference video to guide style, characters, and scene composition. Then describe your desired video in the prompt field — Gemini Omni understands complex scene descriptions including character actions, camera movements (push-ins, orbits, tracking shots), physics interactions, and on-screen text. You can even use sketches or doodles as motion guides for sketch-to-video generation.

Step 2: Configure Settings & Generate

Choose your aspect ratio (16:9 for cinematic content or 9:16 for social media) and duration (4-10 seconds). Click generate and Gemini Omni Flash will create your video using its full-modality fusion engine — combining world knowledge, physics simulation, and your reference materials into a coherent, high-quality clip with natively synchronized audio. Costs 120 credits per second of output.

Step 3: Multi-Turn Edit or Download

Review your generated video and use multi-turn conversational editing to refine it. Swap characters or objects, change wardrobe or backgrounds, adjust lighting, apply style transfers, or modify specific actions — all through natural language. Each edit builds on the previous result, maintaining scene consistency. When satisfied, download your video in MP4 format ready for any platform.

Multi-Turn Conversational Video Editing

Gemini Omni's signature capability. Edit videos through natural language conversation — replace characters, swap backgrounds, change wardrobes, adjust lighting, or modify actions without regenerating the entire scene. Each edit builds on the previous one, maintaining consistency across multiple rounds of refinement. It's like chatting with a video editor who remembers every detail of your project.

Physics-Aware Style Transfer

Transform realistic scenes into entirely different aesthetics while preserving motion and physical dynamics. Apply voxel art, claymation, holographic, liquid metal, monochrome line art, or felt doll styles to any video. The style transfer respects the original video's spatial relationships, object interactions, and movement patterns for stunning, natural-looking artistic transformations.

Native Audio-Video Joint Generation

Unlike most AI video generators that produce silent clips, Gemini Omni generates synchronized audio alongside video output. Sound effects match on-screen actions, ambient audio adapts to the scene environment, and background music synchronizes with visual pacing. This eliminates the need for separate audio tools and creates ready-to-publish content in a single generation step.

World Knowledge & Physics Simulation

Grounded in deep understanding of real-world physics, history, science, and cultural context. Gemini Omni accurately simulates gravity, kinetic energy, fluid dynamics, and material properties. Objects interact realistically — water ripples when touched, fabrics drape naturally, and actions produce logical consequences. This world knowledge makes complex narratives and multi-shot sequences physically and logically coherent.

Cinematic Storytelling: Create multi-shot narrative sequences with consistent characters, realistic physics, and coherent storylines. Use multi-turn editing to refine each scene — swap characters, change locations, adjust lighting — while maintaining visual continuity across shots. Perfect for short films, trailers, and music videos.

Social Media & YouTube Shorts: Generate scroll-stopping vertical videos (9:16) with built-in audio for TikTok, Instagram Reels, and YouTube Shorts. Apply dramatic style transfers — voxel art, claymation, holographic effects — to make your content viral. Native audio generation means your clips are ready to post immediately.

Product Demos & Marketing: Showcase products with physically accurate lighting, materials, and interactions. Generate product walkthroughs, explainer videos, and ad creatives. Use conversational editing to iterate on visual details — change product colors, swap backgrounds, adjust camera angles — until every frame matches your brand vision.

Educational Content & UI Mockups: Create explainer videos with accurate on-screen text rendering — equations, diagrams, UI elements, and labels stay frame-consistent. Gemini Omni's world knowledge ensures scientific and historical accuracy, making it ideal for courseware, tutorials, and technical demonstrations.
