Microsoft has released guidance for system administrators to prevent its Copilot AI from accessing and sharing too much information. The problem occurs when Copilot can see data beyond a user's intended access level, which can result in unwanted data exposure or responses containing information users shouldn't see. The guidance suggests admins should first identify SharePoint sites with lower security risks to test the AI's behavior in a more secure environment. They should then remove sensitive content from Copilot's reach. Finally, they should strengthen privacy by restricting access to pages to specific team members.
Video AI startup RunwayML has introduced a new "Expand Video" feature. It allows users to change video aspect ratios by generating additional content around the original footage using text prompts. The system aims to maintain visual consistency while adding new areas to the frame. The company says users can create camera movements like crash zooms and pull-back shots by combining multiple video expansions. This allows static footage to be transformed into sequences with cinematic camera motion. RunwayML plans to roll out Expand Video gradually for Gen-3 Alpha Turbo users. The company's Runway Academy provides tutorials on using the new feature.
