Veo 3.1 Video FAQ
Common questions about the Veo 3.1 video generation model, its capabilities, and technical requirements.
How does Veo 3.1 video differ from official Google APIs?
We provide a unified OpenAI-compatible SDK for Veo 3.1 video, removing the hurdle of complex IAM setups. You benefit from consolidated billing and flat-rate pricing, avoiding the overhead of managing separate Vertex AI project quotas while accessing the same high-performance cinematic generation features.
What is the maximum duration for Veo 3.1 video clips?
Currently, the Veo 3.1 video preview model generates clips up to 10 seconds long. While this is tailored for high-quality short segments or B-roll, longer narratives can be constructed by stitching multiple generations together using your preferred editing workflow or our automated batch processing features.
What is the expected latency for veo generation?
High-fidelity generation takes time. Typically, a 5-second Veo 3.1 video clip requires between 180 and 300 seconds to process. Because this is a compute-intensive task, we recommend using our asynchronous batch processing for non-urgent creative projects to manage costs effectively.
Is my data used to train the Veo 3.1 video model?
No. When you access Veo 3.1 video through our platform, your requests are routed via the enterprise no-training tier. Your prompts, source images, and generated video files remain private and are never used to improve the underlying Google DeepMind models.
How is Veo 3.1 video generation billed?
We offer flat-rate pricing for Veo 3.1 video. Standard generation costs $0.60 per second, while image-to-video conversion is $0.75 per second. This simplified structure helps teams budget for creative projects without worrying about the variable costs often associated with cloud provider tiers.
Does Veo 3.1 video include safety filtering?
Yes, the model features native integration with Google’s SynthID for digital watermarking. Additionally, every Veo 3.1 video request passes through a proactive safety filter to ensure generated content complies with standard ethical guidelines for AI-generated media.
