In this tutorial, I show you how to outpaint entire video sequences using the powerful VACE 14B model inside ComfyUI. This means expanding your AI-generated video frames beyond their original borders—adding backgrounds, scenery, and dynamic content that feels like it was always there. Whether you're trying to improve aspect ratios, enhance your shots, or add cinematic framing to your AI clips, this guide will show you how to outpaint with precision and style. Perfect for creators working with Wan2.1 or CausVid pipelines looking to push the limits of AI video quality and control.
