Create production-ready synced-audio video with Sora 2 Pro
Last verified: July 24, 2026
Sora 2 Pro is OpenAI’s highest-quality synced-audio video model, introduced on September 30, 2025 as the experimental, higher-quality member of the Sora 2 family; its documented consumer-facing product name was “Sora.” It creates video from natural-language or image input and outputs video with audio.
Within the family, the Pro variant trades render speed for more polished, stable results and is positioned for high-resolution cinematic footage, marketing assets, and work where visual precision matters. The broader Sora 2 system advanced physical accuracy, realism, steerability, synchronized sound, and stylistic range over earlier systems.
OpenAI’s developer catalog labels the model Legacy, and the company’s first-party consumer product ended April 26, 2026. This page supplies an integrated text-to-video and image-to-video generation route directly.

Model audio output
Video plus synchronized audio — OpenAI's wider model sheet
Prepare the scene before you generate
Check the opening frame, timing, composition, sound direction, and safety constraints before committing to a render.
Choose the generation route
Use text-to-video for a scene built from scratch. Choose image-to-video when a still should establish the opening composition; OpenAI documents the image reference as the first frame.
Prepare the still correctly
Confirm that an image-guided input uses JPG, JPEG, PNG or WebP and remains within the page’s file-size limit.
Lock the frame before writing motion
Choose portrait or landscape first, then describe subject placement and camera travel for that composition instead of relying on automatic reframing.
Give one beat enough time
Select the shortest available duration that can contain the full action. Overloading one clip with unrelated events increases continuity risk.
Direct the soundtrack in words
When sound matters, name each speaker, line, environmental layer, and timed effect clearly; OpenAI documents synchronized audio as a model-level output.
Remove blocked likeness and IP requests
OpenAI’s developer guardrails reject real-person generation, human faces in input images, copyrighted characters, and copyrighted music, so replace them with original subjects and sound direction.
Choose OpenAI Pro or Kling O3 for your next video
This comparison keeps separate evidence sets for each variant. The Kling O3 column is locked to Kling VIDEO 3.0 Omni, the exact Omni variant in Kling’s official V3 comparison guide; no O1 or standard V3 specifications are mixed in. The OpenAI column shows this page’s controls first, while “OpenAI's wider model sheet” marks any extra creator-documented option outside them.
| Feature/Spec | Sora 2 Pro | Kling O3 |
|---|---|---|
| Start from the right material | Text prompt or supported still image. | Text, images, video elements and voice references. |
| Fit the scene to one generation | 4, 8, 12, 16 or 20 seconds. | Up to 15 seconds. |
| Select delivery resolution | 720p or 1080p in 9:16 or 16:9. OpenAI's wider model sheet also lists 1024×1792 and 1792×1024. | 720p and 1080p in the February 6, 2026 guide; native 4K in the later 3.0 Omni upgrade. |
| Check still-image requirements | JPG, JPEG, PNG or WebP up to 10 MB. | Up to 7 JPG, JPEG or PNG images; each at least 300 px and up to 10 MB. |
| Plan sound with the picture | Video with synchronized audio — OpenAI's wider model sheet. | Direct audio-visual output with Native Audio. |
| Control reference-driven continuity | A supported still image guides generation on this page; OpenAI documents the input reference as the video’s first frame. | Multi-image, element and video-element references; up to 4 images or elements with video, or 7 without. |
| Launch both sound-and-motion routes from one workspace | Launch the OpenAI Pro workflow directly on Vidofy.ai. | Launch the Kling Omni workflow on Vidofy.ai as well. |
Match the model to the way you direct
Single-brief polish or reference orchestration
The OpenAI Pro route is built for a scene that starts from a written brief or still and needs polished, stable motion with sound conceived alongside the picture. Kling O3—officially documented as VIDEO 3.0 Omni—leans further into combining reference images, video elements, voices, and persistent subjects, which can reduce setup friction when continuity assets drive the project.
Self-contained shots or planned scene coverage
Kling’s official material describes custom multi-shot storyboards and a later native 4K upgrade. The OpenAI materials reviewed do not describe an equivalent shot-by-shot page control, so use the Omni route when one generation must carry planned cuts; use the Pro route when a self-contained shot, longer page duration, and straightforward portrait or landscape delivery matter more.
Choose by scene structure, not model prestige
Use this quick guidance to pick the best option for your workflow.
When to choose each: Choose the OpenAI Pro route for high-fidelity, self-contained campaign or cinematic clips whose dialogue, Foley, action, and camera movement can be specified in one brief. Choose Kling’s Omni route when reference-driven identity, explicit multi-shot structure, or creator-documented 4K finishing is central; confirm the settings exposed for your generation before committing.
Turn a scene brief into a finished video draft
Move from setup to revision in four focused steps.
Step 1: Choose text or image guidance
Start with text-to-video for a scene created from scratch, or select image-to-video when a still should anchor the opening look.
Step 2: Write the production brief
Define the subject, action, camera, lighting, and sound within the 2,048-character prompt field, using the AI prompt helper when you want assistance expanding the direction.
Step 3: Set the delivery controls
Select portrait or landscape framing, a listed clip length, and the resolution that matches your iteration or finishing goal.
Step 4: Generate and refine
Run the generation, inspect continuity and timing, then revise one weak element at a time instead of changing the entire brief.
