OpenAI's Sora App Adds Character Cameos and Video Stitching Tools

OpenAI has updated its invite-only Sora AI video app with tools for creating longer, more narrative videos. A key new feature is character cameos, enabling users to create and reuse characters from uploaded videos. Users can customize character permissions, setting them to private, shared, or public. Sora also introduced video stitching, allowing users to merge multiple clips into a single sequence. The update includes community leaderboards showcasing popular videos and characters. OpenAI temporarily lifted invitation requirements in select countries to coincide with the update. The app has expanded its availability to Thailand, Taiwan, and Vietnam. The launch of character cameos has led to a trademark infringement lawsuit from Cameo against OpenAI. Sora gained over one million downloads faster than ChatGPT despite being invite-only at launch. These updates demonstrate OpenAI's focus on enhancing AI video creation and user engagement.
