Why developers choose EvoLink for Sora 2 Pro

Agencies and platforms use our Sora 2 Pro API integration to deliver client-ready video content with reliable uptime and predictable tiered pricing.

Unmatched Visual Fidelity

Access the 'High' quality tier reserved for Pro users, delivering sharper textures and physics than the base Sora 2 model.

One-Pass Audio Sync

The Sora 2 Pro API generates video and 48kHz audio simultaneously, ensuring frame-perfect synchronization for ads and trailers.

Smart Cost Routing

Leverage EvoLink's infrastructure to access Sora 2 Pro at competitive rates, averaging 20-30% lower than direct list prices.

How to integrate the Sora 2 Pro API

Three simple steps to generate professional video and audio using standard RESTful endpoints.

Step 1 — Configure Payload

Set your `model` to 'sora-2-pro' and define `quality` (Standard/High) and `duration` (10s/15s) in your JSON request.

Step 2 — Prompt with Detail

Submit text prompts including camera angles and audio mood. The Sora 2 Pro API interprets nuance to generate synchronized assets.

Step 3 — Poll & Retrieve

Use our async webhooks to receive the final MP4 file. Download watermark-free assets (if enabled) ready for your timeline.

Sora 2 Pro API vs. Market Alternatives

Compare fidelity, audio capabilities, and cost efficiency

Model	Duration	Resolution	Price	Strength
Sora 2 Pro (Standard/High)	10–15s	Up to 1080p	~$0.20/10s via EvoLink (vs $0.30+ direct)	Superior fidelity, native 48kHz stereo audio, priority API routing.
Sora 2 (Base)	10s	720p/1080p	~$0.10–0.15 per clip	Good general motion, basic audio support, lower cost for prototyping.
VEO3 Fast / Kling	5–8s	720p	From ~$0.36/clip via varied routes	Quick turnaround, decent motion, but lacks Sora 2's complex audio sync.

Sora 2 Pro API - Frequently Asked Questions

Everything you need to know about the product and billing.

The **Sora 2 Pro API** offers distinct advantages: it supports a 'High' quality tier for superior texture and lighting, generates 48kHz stereo audio (vs mono or silent), and provides priority queue processing. It is specifically tuned for professional use cases like advertising and film visualization.

Yes. Unlike previous generations, the Sora 2 Pro API generates synchronized audio by default. This includes lip-synced dialogue, ambient noise, and background music that matches the video's context, delivered as a single multiplexed MP4 file.

Currently, the Sora 2 Pro API supports generation of 10 to 15-second clips. While standard renders are 720p, the Pro tier enables up to 1080p resolution with higher bitrate options for broadcast fidelity.

EvoLink uses smart routing to aggregate volume, offering **Sora 2 Pro API** access at approximately $0.20 per 10s clip (Standard tier). Direct access often lists higher (~$0.28+), making EvoLink a cost-effective choice for scaling applications.

Yes, for qualified commercial accounts, the Sora 2 Pro API allows a `watermark: false` parameter. However, C2PA content credentials metadata remains embedded to ensure transparency and trust in compliance with AI safety standards.

Absolutely. The Sora 2 Pro API returns standard MP4 files compatible with all major editing software (Premiere, DaVinci). It also supports webhook callbacks, making it easy to integrate into automated content pipelines.

Latency depends on the complexity and server load, but the Sora 2 Pro API via EvoLink utilizes priority routing, typically starting generation within seconds and completing a 10s HD clip in under a minute.
