Sora 2 Launches: AI Video Gets More Real, More Controllable

Sora 2 Launches: AI Video Gets More Real, More Controllable The era of synthetic media just turned a major corner. With the unveiling of Sora 2 , OpenAI has raised the bar for what it means to generate realistic video from text—and given users new tools to control how their images and likenesses are used. In this post, we’ll dig into what Sora 2 brings, why it matters, what risks it poses, how creators and rights holders can respond, and what the future may look like. (Spoiler: it’s exciting and complicated.) What Is Sora / Sora 2? To understand Sora 2, it helps to start with Sora itself. Sora is OpenAI’s text-to-video model that generates short video clips (e.g. up to 1080p, under ~20 seconds) from prompts. It also supports remixing existing videos, animating images, and combining text, image, or video inputs. Sora 2 is the next-generation version, powering a new standalone app with a more social, TikTok-style interface . It uses improved video realism, tighter audio-video s...
