What is YouTube's new AI video carousel feature in search results?

YouTube is testing AI-generated video carousels that create highlight clips from existing videos and organize them into search results. This feature is designed to show users the exact content they're looking for without requiring them to click through entire videos. It's primarily being implemented for product-related searches (like 'best noise canceling headphones') and location-based queries. Currently rolling out to a small number of YouTube Premium members, this feature is expected to expand to all users within a few months, making video tags and titles increasingly important for content optimization.
