What is Mora

Mora is a multi-agent framework designed to facilitate generalist video generation tasks, leveraging a collaborative approach with multiple visual agents. It aims to replicate and extend the capabilities of OpenAI's Sora. Task

📹 Demo for Artist Creation

Inspired by OpenAI Sora: First Impressions, we utilize Mora to generate Shy kids video. Even though Mora has reached the similar level as Sora in terms of video duration, 80s, Mora still has a significant gap in terms of resolution, object consistency, motion smoothness, etc.

Mora: A Multi-Agent Framework for Video Generation

test image

Multi-Agent Collaboration: Utilizes several advanced visual AI agents, each specializing in different aspects of the video generation process, to achieve high-quality outcomes across various tasks.
Broad Spectrum of Tasks: Capable of performing text-to-video generation, text-conditional image-to-video generation, extending generated videos, video-to-video editing, connecting videos, and simulating digital worlds, thereby covering an extensive range of video generation applications.
Open-Source and Extendable: Mora’s open-source nature fosters innovation and collaboration within the community, allowing for continuous improvement and customization.
Proven Performance: Experimental results demonstrate Mora's ability to achieve performance that is close to that of Sora in various tasks, making it a compelling open-source alternative for the video generation domain.
