Ship cinematic, synced-audio clips with Sora 2 Pro—without wrestling the workflow
Sora 2 Pro (sora-2-pro) is OpenAI’s higher-quality, second‑generation Sora variant for generating video with synced audio, available via the Sora Video API. OpenAI announced Sora 2 on September 30, 2025 , and the OpenAI API documentation positions Sora 2 Pro as its most advanced synced‑audio video generation option. ([openai.com](https://openai.com/index/sora-2/))
For creators, the key value of Sora 2 Pro is repeatable, parameterized control: you can explicitly set clip length and output size in the API request, then monitor the asynchronous render job until completion. In the OpenAI Video API, seconds supports 4 / 8 / 12 seconds and size supports 720x1280, 1280x720, 1024x1792, or 1792x1024 —so you can standardize outputs across a campaign (social, ads, product loops) instead of “hoping” a generation fits your delivery format.

Vidofy.ai makes Sora 2 Pro practical at production pace: pick the model, lock your technical settings, generate, then iterate (including remix-style prompt updates when you want variations) in one place—without building your own job manager around the API’s async lifecycle.

Cinematic Fidelity vs Unified Editing: Sora 2 Pro vs Kling O1
Both models target modern “director-style” creation, but from different angles: Sora 2 Pro is optimized for production-quality, synced-audio video generation through OpenAI’s Sora Video API, while Kling O1 is presented by Kuaishou as a unified multimodal creation tool combining generation and editing in one engine. Kling O1 was officially unveiled on December 1, 2025 . ([platform.openai.com](https://platform.openai.com/docs/models/sora-2-pro))

Detailed Analysis
Analysis: Production-ready clips with synced audio
Sora 2 Pro is explicitly documented as a synced-audio video generation model in the OpenAI API, which matters when you’re producing shots where timing (dialogue beats, sound effects, ambience) must match the visual action. In practical creator workflows, this reduces the need to “patch” audio after generation just to make a concept watchable. ([platform.openai.com](https://platform.openai.com/docs/models/sora-2-pro))
Analysis: Parameterized control (seconds + size) vs a unified editing promise
OpenAI’s Video API reference clearly enumerates allowed seconds and size values, which makes Sora 2 Pro easier to standardize across deliverables and templates—especially inside a product layer like Vidofy that can save presets and enforce consistency. Kling O1’s official announcement emphasizes unifying generation + editing tasks into one engine and highlights temporal control between 3–10 seconds, but does not (in the official announcement) publish the same kind of enumerated output-size matrix for developers to lock into production specs.

Verdict: Choose Sora 2 Pro when “final output” quality and synced audio matter
How It Works
Follow these 3 simple steps to get started with our platform.
Step 1: Describe a single shot (not a whole film)
Write a focused prompt with subject, setting, lighting, and camera movement. If you want synced sound, describe the exact audio cues that should align with the action.
Step 2: Choose Sora 2 Pro + your technical settings
Select Sora 2 Pro, then set duration and output size to match your delivery format. Use a reference image when you need the shot to anchor on a specific visual direction.
Step 3: Generate, review, and iterate with controlled variations
Run the render job, review the result, then refine with prompt adjustments to create variations (angle, timing, lighting, staging) while keeping the same technical spec preset.
Frequently Asked Questions
What is Sora 2 Pro?
Sora 2 Pro (sora-2-pro) is OpenAI’s higher-quality Sora 2 variant for generating video with synced audio, available through the OpenAI API.
What video lengths can I generate with Sora 2 Pro in the OpenAI API?
The OpenAI Video API lists allowed seconds values of 4, 8, or 12 seconds .
What output sizes (resolutions) are supported?
The Video API reference lists allowed size values: 720x1280, 1280x720, 1024x1792, and 1792x1024 .
Does Sora 2 Pro include audio?
Yes—Sora 2 Pro is documented as outputting video and audio (synced-audio video generation).
Are there restrictions around real people or faces?
OpenAI’s Sora API documentation and Sora usage policies describe restrictions designed to prevent harmful misuse, including limitations around generating real people and the use of human faces in input images.
Who owns the videos I generate—can I use them commercially?
OpenAI’s Terms of Use state that, as between you and OpenAI (and to the extent permitted by law), you retain ownership of your input and you own the output. Your use must still comply with OpenAI’s applicable terms and policies.
