Sora 2 AI Video Generator

Sora 2 introduces revolutionary synchronized audio generation alongside video, including realistic dialogue and sound effects. It features enhanced physics accuracy ensuring natural object interactions, improved temporal consistency eliminating morphing artifacts, and innovative Cameo technology allowing users to insert themselves into AI-generated scenes. The model delivers up to 1080p resolution with extended video lengths of 30-60 seconds.

Sora 2 generates videos up to 1080p resolution with lengths ranging from 10 seconds in the app to 20 seconds via web interface. The model supports 16:9 landscape and 9:16 portrait aspect ratios, making it suitable for various platforms from YouTube content to social media shorts. It accepts prompts up to 4,000 characters for detailed scene descriptions.

Sora 2 features native audio synthesis that automatically generates realistic dialogue, sound effects, and ambient soundscapes perfectly synchronized with video content. The model understands scene context and creates appropriate audio for every visual element, from character conversations to environmental sounds like footsteps and ambient noise, marking a significant advancement over silent AI video generation.

Cameo is an innovative feature that allows users to insert themselves into AI-generated scenes. Users upload a one-time video-and-audio recording to verify their identity and capture their appearance. Once recorded, users can share their cameos with friends, allowing others to include their likeness in Sora-generated videos with realistic integration and proper context awareness.

Sora 2 features an advanced physics engine that accurately models gravity, momentum, collision dynamics, and buoyancy. Unlike previous models where objects might morph or teleport, Sora 2 ensures realistic interactions - basketballs bounce naturally off backboards, water responds correctly to objects, and characters perform complex movements with believable physics throughout every frame.

While Sora 2 represents a major advancement, it has some limitations: videos are capped at 1080p resolution (not 4K), generation times can be longer for complex scenes, the Cameo feature requires initial setup and identity verification, and the model is currently available primarily in the US and Canada. The service requires a ChatGPT Pro subscription for unrestricted access to the Sora 2 Pro model.
