The latest addition to Pika's features is the Lip Sync functionality, which allows users to effortlessly synchronize mouth animations with audio in their videos. By uploading an audio file and selecting an animated character, the Pika system automatically syncs the audio with the character's mouth animation, providing users with a more vivid and realistic video experience. Additionally, Pika offers other features such as video frame expansion and style adjustments, enabling users to easily create rich, creative video content.
