The Learning and Vision Lab team at the National University of Singapore has developed a distributed long video generation tool called Video-Infinity. This tool breaks through the bottleneck of existing long video generation technology and has attracted much attention for its efficiency, convenience and powerful functions. . It can quickly generate high-quality long videos in a multi-GPU environment without additional training models, significantly shortening video generation time and greatly improving production efficiency. Users can realize personalized video generation needs through simple configuration, and optimize video quality through parameter adjustment.

This tool is distributed, high-speed and training-free. It is installed using the conda environment and is easy to use. Users can perform basic configuration, pipeline configuration and Video-Infinity configuration as needed to achieve different video generation needs.
At the same time, in order to avoid high-frequency information loss, it is recommended to set the sum of the number of local context frames and the number of global context frames of the Attention model below 24 to maintain video quality and stability.
By comparing the experimental results, this technology not only has obvious advantages in the number of video frames, but also performs well in terms of time cost. The technical team stated that their method achieved this achievement with the support of 8 Nvidia Ada6000 GPUs, and the sampling step was set to 30.
Researchers of this technology also conducted confrontation experiments to analyze the effects of Clip Parallelism and Dual-scope Attention through ablation. The results showed that these two factors have a significant impact on video generation. In addition, this technology also supports multiple prompts (Multi-Prompts), which can achieve smooth transitions of backgrounds, styles and themes, providing more possibilities for video generation.
Highlights:
⭐ This technology can generate a video with 2300 frames in 5 minutes, 100 times faster than previous methods;
⭐ Clip Parallelism and Dual-scope Attention have a significant impact on video generation;
⭐ Supports multiple prompts (Multi-Prompts) to achieve smooth transition.
The emergence of Video-Infinity marks a major breakthrough in long video generation technology. Its efficient generation speed and convenient operation will bring revolutionary changes to film and television production, animation creation and other fields, providing users with a more convenient and efficient video creation experience. We look forward to further development of this technology in the future, bringing more powerful video generation capabilities to more users.
