What is FancyVideo?
FancyVideo is an AI-powered text-to-video (T2V) model developed by 360 in collaboration with Sun Yat-sen University. Based on its innovative Cross-frame Textual Guidance Module (CTGM), it can generate dynamic, rich, and temporally coherent video content based on text prompts. FancyVideo significantly improves the quality and naturalness of text-to-video (T2V) generation tasks. FancyVideo is open-source, with a rich codebase and documentation, facilitating further exploration and application by researchers and developers. The official FancyVideo website provides intuitive demonstrations and user guides, allowing non-technical users to quickly understand its functionality and potential.
FancyVideo's main functions
- Text to video generationUsers only need to provide a text description, and FancyVideo can generate video content, realizing the transformation from text to dynamic visuals.
- Cross-frame text guidanceThe CTGM module enables the model to dynamically adjust between different frames, generating coherent and logical videos.
- High-resolution video outputFancyVideo supports the generation of high-resolution videos, meeting the demand for high-quality video content.
- Time consistency maintenanceThe objects and actions in the video maintain temporal continuity, resulting in a more natural and realistic video.
FancyVideo's technical principles
- Text-to-Video Generation:FancyVideo uses deep learning models, particularly diffusion models, to transform text descriptions into video content.
- Cross-frame textual guidance:The Cross-frame Textual Guidance Module (CTGM) enables coherent text guidance between different frames of a video, ensuring the temporal continuity and dynamism of the video content.
- Temporal Information Injection:When generating each frame, the model injects time-related information to ensure that the transitions between video frames are natural and conform to the dynamic changes described in the text.
- Temporal Affinity Refinement:Temporal Affinity Refiner (TAR) is used to optimize the temporal correlation between frame-specific text embeddings and the video, enhancing the logical consistency of text guidance.
- Temporal Feature Boosting:Temporal Feature Booster (TFB) further enhances the temporal consistency of latent features, ensuring smoothness and stability during continuous video playback.

How to use FancyVideo
- Get the modelFrom FancyVideo's official websiteGitHub repositoryDownload the FancyVideo model and its dependencies.
- Prepare the environmentEnsure that Python and necessary deep learning frameworks (such as PyTorch) are installed in the computing environment, and install all necessary libraries and tools according to FancyVideo's documentation.
- Understanding input formatUnderstand the input text format required by FancyVideo; text prompts will guide the model in generating video content.
- Write a text promptWrite a text description based on the desired video content. The description needs to be specific enough for the model to understand and generate the corresponding video.
- Operating ModelUse the scripts or command-line tools provided by FancyVideo, enter a text description, and run the model. The model will generate a video based on the text prompts.
- Adjust parametersDuring the generation process, some parameters need to be adjusted, such as video length, resolution, and frame rate, to obtain the best video effect.
