Pixverse Extend
Pixverse Extend is a specialized video extension model that takes an existing video clip and generates a seamless continuation. It preserves the original motion, style, and scene context while extending the footage beyond its original duration.
Pixverse Extend focuses exclusively on video-to-video extension. Feed in a clip and the model continues the scene with consistent motion, lighting, and composition. This makes it valuable as a post-processing step when AI-generated or real-world footage needs to be longer. It does not support text-to-video or image-to-video — its single purpose is extending existing video content.
