## [Veo 3 API](https://www.cometapi.com/veo-3-api/) |
|
|
|
|
|
## ***Model Page:***[Midjourney Video API](https://www.cometapi.com/midjourney-video-api/) |
|
|
|
|
|
The Veo 3 API is a RESTful endpoint on Google Vertex AI that enables developers to generate synchronized, high‑resolution video and audio clips from text or image prompts—complete with built‑in safety filters and imperceptible watermarking—in a single request. |
|
|
|
|
|
Google DeepMind’s **Veo 3** represents the cutting edge of **text-to-video generation**, marking the first time a large-scale generative AI model seamlessly synchronizes **high-fidelity video** with **accompanying audio**—including dialogue, sound effects, and ambient soundscapes. |
|
|
|
|
|
## Core **Features** and Capabilities |
|
|
|
|
|
- **8‑Second Video Clips**: Generates up to eight‑second sequences with seamless shot transitions and stitching. |
|
|
- **Integrated Audio Generation**: Produces dialogue, ambient noise, sound effects, and background music in a single pass. |
|
|
- **High‑Definition Output**: Supports resolutions up to **4K (3840 × 2160)** with consistent lighting, realistic physics, and detailed scene textures. |
|
|
- **Multi‑Modal Inputs**: Accepts both **text‑to‑video** and **image‑to‑video** prompts, enabling versatile creative workflows. |
|
|
|
|
|
These capabilities empower creators to craft near‑cinematic narratives without separate audio post‑production or complex editing pipelines . |
|
|
|
|
|
## Benchmark Performance |
|
|
|
|
|
In internal benchmarks, Veo 3 demonstrates: |
|
|
|
|
|
- **PSNR** (Peak Signal‑to‑Noise Ratio) of **38 dB** on standard video datasets, outperforming Veo 2 by **4 dB**. |
|
|
- **SSIM** (Structural Similarity Index) scores of **0.92**, indicating high visual fidelity. |
|
|
- **Audio–Video Sync Error** below **15 ms**, ensuring imperceptible lag between sound and motion. |
|
|
- **Inference Speed**: ~**12 frames per second** on an NVIDIA A100 GPU, enabling near real-time generation for short clips. |
|
|
These metrics position Veo 3 at the forefront of generative video AI, eclipsing contemporaries like Sora and Meta’s recent video models in both **quality** and **synchronization**. |
|
|
|
|
|
## Model Versions and Evolution |
|
|
|
|
|
- **Veo 1** (May 2024): Launched at Google I/O 2024, introduced **1080p silent video** generation over one minute. |
|
|
- **Veo 2** (December 2024): Upgraded to **4K support** and improved **physical dynamics** understanding . |
|
|
- **Veo 3** (May 2025): Added **audio synthesis**, **enhanced realism**, and **4K output**, marking a significant leap in **multimodal generation**. |
