VEO 3.1 Video Generator - Google's Latest AI Video Model with 148s Scene Extension We've built a platform that provides access to Google's VEO 3.1, the latest video generation model released in October 2025. This represents a significant leap in AI video capabilities, and we wanted to share what makes it interesting from a technical perspective. What's New in VEO 3.1 Extended Scene Duration: VEO 3.1 can generate videos up to 148 seconds through scene continuation technology. The model analyzes final frames and generates seamless continuations, maintaining narrative coherence across extended sequences. Synchronized Audio Generation: Unlike previous models, VEO 3.1 generates audio alongside visuals with unprecedented synchronization. Environmental ambience, sound effects, and spatial audio mixing are synthesized to match on-screen actions frame-by-frame. Advanced Motion Physics: The model incorporates sophisticated physics simulation for realistic object movement, fluid dynamics, and character animation. This addresses one of the major challenges in AI video generation - maintaining physical consistency. Reference Image Control: Upload up to three reference images to guide character generation, maintaining consistent appearance across sequences. This is particularly useful for maintaining brand consistency or character continuity in longer narratives. Frame Interpolation: Generate smooth transitions between static images using frames-to-video capability, creating natural motion paths between compositions. Technical Specifications

Resolution: 720p or 1080p at 24 FPS Aspect Ratios: 16:9 (landscape) and 9:16 (portrait) Base Generation: 4-8 second clips Extended Generation: Up to 148+ seconds via scene continuation Dual Modes: Standard quality or Fast mode for rapid iteration

Use Cases We're Seeing Pre-visualization: Filmmakers using it for concept testing before full production, sharing directly with producers and investors. Educational Content: Institutions creating engaging educational videos with consistent character appearance across modules. Marketing Agencies: Rapid prototyping of campaign ideas, reducing revision cycles through enhanced prompt adherence. Corporate Communications: Internal teams accelerating presentation production while maintaining professional standards. The "Ingredients Mode" One interesting feature is what VEO 3.1 calls "Ingredients Mode" - you can combine multiple reference images as compositional elements, controlling characters, objects, and stylistic elements simultaneously. The model synthesizes these into cohesive scenes. Commercial Licensing All generated content comes with full commercial licensing, making it viable for professional deployment, client presentations, and commercial distribution. What We've Learned The biggest technical challenge has been maintaining quality consistency across extended generations. The scene extension feature works by analyzing terminal frames, but ensuring visual coherence over 148 seconds requires careful prompt engineering. Audio-visual synchronization is surprisingly robust - the model understands temporal relationships between sound and motion better than we initially expected. Try It We've set up a demo at https://sora2videogenerator.com/veo31 where you can experiment with the model.
