📋 News

• [2025.10.9] Release Arxiv paper.

📖 Introduction

VideoCanvas has two key contributions:

• 🎯 Unified Tasks: VideoCanvas introduces a unified paradigm for arbitrary spatio-temporal video generation, seamlessly integrating diverse capabilities including image/patch-to-video conditioning at any timestamp, inpainting/outpainting, camera control, scene transitions, and video extension.
• 🛠️ Simple Solution: Our technical innovation leverages In-Context Conditioning with zero-padding for spatial control and Temporal RoPE Interpolation for temporal alignment, achieving frame-precise video generation without fine-tuning VAEs or adding parameters. <br>
