What is Veo3.1 Fast Video 1080p?
**Veo3.1 Fast Video 1080p** is a fast video generation model available through UniAll AI. The public model id is `veo3.1-fast-video-1080p`.
It is designed for short-form AI video workflows where speed, 1080p output, and flexible input modes matter. The model supports asynchronous generation and can be used for product videos, ad creatives, social clips, storyboard previews, and automated video production pipelines.
Core capabilities
The model supports multiple generation modes:
- **Text to video**: create video from a prompt.
- **Image to video**: animate a reference image.
- **First/last frame video**: guide motion between a starting and ending frame.
- **Video to video / video edit**: use a source video as input.
- **Reference media to video**: generate with media guidance where supported by the selected mode.
- **Video extension**: continue or extend video-style content in compatible workflows.
Supported media inputs include PNG, JPEG, WebP images and MP4, QuickTime, or WebM source video files.
Key parameters
Typical request fields include:
| Parameter | Description | |---|---| | `model` | Use `veo3.1-fast-video-1080p` | | `generation_mode` | Examples: `text_to_video`, `image_to_video`, `first_last_frame`, `video_to_video` | | `prompt` | Required text instruction for the scene, motion, style, and camera behavior | | `duration` | 4, 6, or 8 seconds | | `aspect_ratio` | `16:9` or `9:16` | | `resolution` | `720p`, `1080p`, or `4k` options are exposed in the interface; this model variant is optimized for fast 1080p workflows | | `generate_audio` | Optional audio generation toggle | | `image_url` | Reference image for image-to-video | | `first_image_url` / `last_image_url` | First and last frame guidance | | `video_url` | Source video for video edit workflows |
Each generation returns one video per task.
API usage
UniAll AI exposes the model through an async video generation endpoint:
```http POST /v1/videos/generations Content-Type: application/json ```
Example request:
```json { "model": "veo3.1-fast-video-1080p", "generation_mode": "text_to_video", "prompt": "A cinematic product reveal of a matte black smart speaker on a reflective table, soft studio lighting, slow dolly-in camera movement.", "duration": 8, "aspect_ratio": "16:9", "resolution": "1080p", "generate_audio": true, "video_count": 1 } ```
For image-to-video, add `image_url` and set `generation_mode` to `image_to_video`. For first/last-frame generation, provide both `first_image_url` and `last_image_url`.
Because generation is asynchronous, applications should submit a task, store the task id returned by the API, and poll or consume task status according to their UniAll AI integration pattern.
Pricing and billing
Veo3.1 Fast Video 1080p is billed by generated video seconds. The listed user price for the fast 1080p video option is **$0.068 per second** without audio and **$0.102 per second** with audio. Pricing can vary by account type, region, plan, and selected resolution/audio option, so production users should confirm the current rate in their UniAll AI console before scaling.
Example cost estimate:
- 8-second 1080p video without audio: `8 × $0.068 = $0.544`
- 8-second 1080p video with audio: `8 × $0.102 = $0.816`
Failed generations are eligible for refund handling when supported by the platform configuration.
Who should use it?
This model is a strong fit for:
- Developers building AI video generation features into apps.
- Marketing teams producing ad variations and social assets.
- E-commerce teams creating product showcase clips.
- Creative studios testing storyboards and motion concepts.
- Automation teams connecting video generation to CMS, DAM, or campaign workflows.
- Agencies or platform operators who need API-based video generation access through UniAll AI.
Practical prompt tips
For better results, describe:
1. Subject: what appears in the scene. 2. Motion: how the subject or camera moves. 3. Style: cinematic, documentary, product render, handheld, macro, etc. 4. Composition: close-up, wide shot, top-down, centered framing. 5. Lighting and environment: studio lighting, neon city, sunset, clean white background. 6. Output intent: ad creative, product demo, vertical social video, storyboard shot.
Example:
```text A 9:16 vertical fashion ad showing a model walking through a rainy neon street at night, cinematic reflections on wet pavement, slow tracking shot, shallow depth of field, premium editorial style. ```
Why use it through UniAll AI?
UniAll AI provides a unified API layer for AI media generation, making it easier to connect video models to production workflows. Teams can use a consistent request pattern, manage billing, and integrate async video generation without building separate infrastructure for each model provider.
