Introduction
Complete guide to using Affordable Veo 3.1 Official API for Production Video Workflows
Affordable Veo 3.1 Official API for Production Video Workflows
PoYo brings fast, lite, quality and extension workflows into one async video API. Generate short clips from prompts, guide motion with images, add native audio when needed, or continue an existing video with extension controls.
Available Veo 3.1 Official Models
02
veo3.1-lite-official
The lower-cost tier for higher-volume generation. Use it for prompt-only, single-image and first/last-frame workflows at 720p or 1080p.
03
veo3.1-quality-official
The high-fidelity tier for final creative output, cinematic product shots and 4K-capable generation. It also supports three-image generation_type reference inputs.
04
veo3.1-extend
A continuation workflow for adding 1-7 seconds to an existing clip while keeping the final video within the supported length cap.
Key Features of Veo 3.1 Official API
Use the same PoYo async pattern across fast iteration, low-cost generation, high-fidelity output and video continuation.
01
Choose the right tier for speed, cost or fidelity
Veo 3.1 Official on PoYo is organized around four public models. Fast is useful for iteration, lite keeps per-second cost low, quality targets higher-fidelity and 4K-capable output, and extend continues a source video.
- Fast, lite, quality and extend tabs
- Pricing changes by model, resolution and audio setting
- One submit/status workflow for the full family
02
Control generation with prompts and image guidance
Start with a prompt, animate one image, define a first and last frame with two images, or use three reference images on supported tiers. This makes the page practical for both open-ended ideation and more directed brand or product scenes.
- Prompt-only text-to-video
- One image for image-to-video
- Two images for first/last-frame transitions
- generation_type reference with three images on fast and quality
03
Generate with audio or extend an existing clip
Keep the audio switch on when the prompt needs ambience, sound effects or dialogue-like cues, or turn it off for lower-cost silent clips. For continuation work, provide a video URL and choose an extension duration from 1 to 7 seconds.
- Audio-enabled and silent generation options
- Extension workflow uses a source video URL
- PoYo validates extension length against the final 30-second cap
What Teams Build With Veo 3.1 Official API
01
Ad and campaign concepts
Create short cinematic variations from prompts or visual references before committing to a final direction.
02
Product motion assets
Animate product imagery, preserve object appearance with references, and generate vertical or landscape clips for launch pages and ads.
03
Storyboard transitions
Use first/last-frame generation when the opening and ending composition are already defined.
04
Scene continuation
Extend an existing video when a shot needs a few more seconds of motion, ambience or narrative continuity.

Veo 3.1 Official API FAQ
Which Veo 3.1 official model should I use first?
Start with veo3.1-fast-official when you want a balanced default. Use veo3.1-lite-official for lower-cost volume, veo3.1-quality-official for final higher-fidelity clips or 4K, and veo3.1-extend when you already have a source video to continue.
How does PoYo decide between text-to-video, image-to-video and reference generation?
For generation models, no images creates text-to-video, one image creates image-to-video, two images create first/last-frame video, and three images use generation_type=reference on the tiers that support it.
Does veo3.1-lite-official support generation_type=reference?
No. The lite tier supports prompt-only, one-image and two-image first/last-frame workflows. Use fast or quality when you need generation_type=reference with three images.
Can I turn off audio?
Yes. PoYo exposes a sound control. Leave it on for native audio generation, or turn it off when you want a silent clip or a lower-cost request.
How does veo3.1-extend duration work?
For veo3.1-extend, duration can be 1 through 7 seconds and defaults to 7. PoYo checks the source video length and rejects requests that would make the final video exceed 30 seconds.
How does PoYo pricing compare with fal.ai for Veo 3.1 Official?
PoYo is 50% lower than fal.ai on veo3.1-fast-official and 40% lower on veo3.1-lite-official, veo3.1-quality-official and veo3.1-extend, using the same per-second resolution and audio tiers shown on this page.
What fields should I send in the API request?
Use the PoYo fields shown in the documentation: prompt, image_urls, generation_type, duration, aspect_ratio, resolution, sound, video_url and callback_url. Fields that are not exposed by PoYo should not be sent.
