Brick-Diffusion: A Novel Approach to High-Fidelity Long Video Generation

Sunday 02 March 2025


The quest for high-fidelity long video generation has been a longstanding challenge in the field of computer vision. While significant progress has been made in recent years, existing methods still fall short in terms of quality and consistency. Enter Brick-Diffusion, a novel approach that leverages pre-trained video diffusion models with a brick-to-wall denoising strategy to produce long videos of arbitrary length.


The problem with current methods is that they often rely on concatenating short clips together, which can lead to noticeable content changes between frames. To address this issue, Brick-Diffusion employs a brick-to-wall denoising technique, where the latent is divided into segments and denoised individually. This process enables communication between frames, resulting in consistent and high-fidelity long videos.


The authors’ approach is built upon a pre-trained video diffusion model, which is trained to learn a data distribution by gradually denoising a variable sampled from a Gaussian distribution. The brick-to-wall denoising strategy is then applied to this latent, allowing for efficient processing and parallelization.


The experimental results demonstrate the effectiveness of Brick-Diffusion in generating high-quality long videos. Compared to existing baseline methods, Brick- Diffusion outperforms them across various metrics, including subject consistency, dynamic degree, aesthetic quality, and overall video-text consistency.


One of the key advantages of Brick-Diffusion is its ability to generate videos with high fidelity and motion dynamics. The method produces realistic and engaging videos that are on par with state-of-the-art results in terms of visual quality. Additionally, Brick- Diffusion can be easily parallelized, making it a scalable solution for long video generation.


The limitations of Brick-Diffusion are primarily related to the pre-trained video diffusion model used as a foundation. While this model is capable of generating high-quality short videos, it may not generalize well to all types of content and scenarios. Future work could focus on developing more robust and adaptable pre-training methods that can better handle diverse input data.


In summary, Brick-Diffusion represents a significant step forward in the quest for high-fidelity long video generation. By leveraging pre-trained video diffusion models with a brick-to-wall denoising strategy, this method is capable of producing consistent and realistic videos that are on par with state-of-the-art results. With its scalability and parallelization capabilities, Brick-Diffusion has the potential to revolutionize various applications, including entertainment, education, and marketing.
