Sora 2: The Next Generation of Video Production with Realistic Sound and Physics

Sora 2: نسل جدید تولید ویدیو با صدا و فیزیک واقع‌گرایانه

Introduction

In the fast-paced world of artificial intelligence, transformations happen rapidly, but some advancements are so powerful they shift the boundaries of what's possible. Sora 2 is OpenAI's new generation video and audio generation model, designed with higher physical accuracy, greater realism, and improved controllability, offering for the first time the capability to generate dialogue and sound effects simultaneously.
This new generation, launched in September, is a response to the criticisms and limitations of the first version. If the initial Sora demonstrated that text-to-video generation was possible, Sora 2 introduces capabilities that were challenging for previous video models - including more precise physics, greater realism, simultaneous audio, improved directability, and a broader stylistic range - showing that this technology is ready for practical use.
Unlike the first generation, which was primarily a technology demonstration, Sora 2 has become a complete content production platform with its dedicated application, advanced editing tools, and more public access. This shift represents a change in perspective from "experiment" to "professional tool."

Key Advancements of Sora 2 Over the First Generation

Realistic Physics: The End of Motion Problems

One of the biggest challenges of the first generation of Sora was violations of physics laws. Objects would suddenly disappear, movements were unnatural, and gravity wasn't properly simulated. Sora 2 is designed to model failure states and better follows the everyday physics that filmmakers expect.
Now if you throw a basketball in a generated scene, it follows a natural parabolic trajectory, hits the ground, and bounces with realistic behavior. This same precision is observed in simulating water, smoke, fabric, and any other physical element.

Simultaneous Audio: A New Dimension in Visual Experience

Sora 2's biggest innovation is adding realistic audio synchronized with video. This model generates believable background audio, speech, and sound effects for the first time, and like Google Veo 3, it strives to keep image and sound synchronized.
This feature has created a real transformation in content production. There's no longer a need to separately add music or sound effects. Sora 2 can:
  • Generate natural dialogue between characters
  • Simulate footstep sounds on different surfaces
  • Create background music appropriate to the scene's atmosphere
  • Add environmental effects like wind, water, or traffic sounds

Video Length and Quality: From Demonstration to Professional Production

Users can generate videos up to 10 seconds at 720p resolution (in Free and Plus plans) or 20 seconds at 1080p resolution (in Pro plan). This significant increase in length and quality makes professional use possible.
For comparison, the first generation was limited to shorter clips with lower quality. This advancement means the ability to produce content usable in real projects.

Dedicated Application and Improved User Experience

Another important change is the launch of the dedicated Sora application. This app, with its intuitive user interface and built-in editing tools, has greatly simplified the content production process. Users no longer need to use different platforms and can perform all stages of production, editing, and sharing in one integrated environment.

Advanced Capabilities for Unlimited Creativity

Cameo: Placing Real People in Generative Scenes

One of the most attractive new features is Cameo. This capability allows users to place actual images of themselves or others in generated scenes. Imagine seeing yourself in an action movie, an animation, or a historical scene - all possible with a few clicks.
This feature is not only useful for entertainment but is also used for producing personalized advertising, educational, and even cinematic content. Of course, OpenAI has imposed strict limitations to prevent misuse of this capability, given security concerns.

More Advanced Editing Tools

Sora 2 comes with more extensive editing tools than the first generation:
Advanced Remix: Now you can completely change a video's style - from cinematic to anime, from realistic to oil painting. This is done while preserving the original content and scene structure.
Smart Re-cut: Editing and cutting videos is done with content understanding. The algorithm knows which parts are important and performs removal or shortening without losing the original message.
Seamless Loop: Creating repetitive loops that connect seamlessly - ideal for social media content and live wallpapers.
Blend with Precise Control: Combining multiple videos or styles with precise control over the amount and method of blending. This feature is unparalleled for creating unique artistic content.
Professional Storyboard: Designing complex multi-scene sequences with complete control over timing, transitions, and narrative flow.

Video Extension and Completion

Sora 2 can extend existing videos not only forward but also backward. This capability is used for:
  • Increasing the length of short clips to standard length
  • Adding introductions or conclusions to existing videos
  • Filling time gaps in sequences
  • Creating longer versions for different platforms
All these operations are performed while maintaining quality, narrative consistency, and original style.

Image-to-Video with More Detail
