Sora 2

Synchronized audio is built into Sora 2, so dialogue, sound effects and background music are generated along with the video instead of added afterward.

Sora 2 is an AI video generator from OpenAI that turns text prompts or images into clips, in realistic cinematic footage or anime styles.

It simulates physics with object permanence, and it can follow multi-shot instructions while keeping the scene consistent from one shot to the next.

A cameo feature lets you put a person into a video with their appearance and voice, and consent controls and wellbeing features come with it.

Access is free to start, with limits described as generous.

The catch is availability: the first rollout covers only the US and Canada, you need to sign up and get an invite, and the higher quality Pro model is for ChatGPT Pro users.
