Everything you need to build
AI-powered applications
Our API provides comprehensive access to cutting-edge AI tools, enabling you to build sophisticated applications with ease.
Cinema-Grade Audio-Visual Quality
Compared to Veo 3, audio realism is improved by 40%. Automatically generates synchronized dialogue, sound effects, and ambient audio for more natural audio-visual alignment.
Extreme Visual Consistency
Compared to Veo 3, frame consistency is improved by 40–60%. Dramatically reduces distortion artifacts and ensures stable lighting and object coherence within 8-second sequences.
Precise Cinematic Control
Compared to Veo 3, prompt adherence is improved by 35%. Supports shot directives such as wide-angle, dolly, zoom, and tracking shots — ensuring your creative vision is executed accurately.
Character & Style Anchoring
Supports uploading up to 3 reference images. Maintains high consistency in character appearance, artistic style, and visual elements throughout video generation.
148-Second Long-Scene Extension
Supports text-to-video and image-to-video, with seamless multi-clip stitching to easily create multi-shot narratives up to 148 seconds.
Efficient Dual-Model Options
Offers Fast and Quality modes. Both support 1080p output, balancing speed and visual fidelity.
New Capabilities of Google Veo 3.1 API
Discover how Veo 3.1 elevates AI video generation with finer control, stronger consistency, and native audio-visual realism—built for scalable, production-ready workflows.
Precise Shot Control and Multi-Image Guidance
Crun integrates the Veo 3.1 API to support synchronized first-and-last frame control. By defining the start and end images, the AI interpolates precise motion paths. It also supports multi-image referencing, allowing creators to lock in character design, environment, and lighting simultaneously to ensure visual consistency throughout the shot.
Character Consistency and Narrative Extension
The model eliminates character "flickering" by using reference images to lock identity traits across multiple frames. To meet long-form storytelling needs, Crun offers an intelligent extension feature that naturally continues motion based on the dynamics of the previous clip, breaking the 8-second limit for more complex narratives.
Native Audio Sync and Physical Logic Simulation
Veo 3.1 features native audio modeling, generating videos with synchronized sound effects—such as lip-sync and ambient noise—tied directly to the action. Combined with a robust physics engine, the model accurately simulates light reflection, gravity, and object collisions, delivering a high degree of realism in both sight and sound.
Performance Optimization with Veo 3 Fast
For high-frequency production, Crun provides the Veo 3 Fast version, optimized for speed and cost-efficiency. This model enables rapid conversion of text or images into high-quality video with audio, making it ideal for social media, advertising, and other commercial environments requiring rapid iteration and large-scale output.
Improvements in Veo 3.1 API Compared to Earlier Versions
Google currently offers multiple Veo video generation models, including Veo 3.1, Veo 3, and Veo 2, covering capabilities from basic text-to-video generation to high-fidelity video creation with native audio and advanced cinematic control.The comparison below highlights the key technical differences between each version.
