Introduction

Comfy UI is a powerful tool that excels in animation creation, offering fast generation times, broad applicability, and low VRAM consumption. While it may be challenging for beginners due to its use of nodes, it's relatively simple to implement Stable Video Diffusion with Comfy UI. In this guide, we will cover the installation process and provide step-by-step instructions for creating various animations using Comfy UI.

Installing Comfy UI

To begin, ensure that You have a computer with an NVIDIA GPU and at least 12 GB of video memory. Install Python and git as prerequisites. If you already have a local environment set up for stable video diffusion, proceed to the Comfy UI installation process. Download the Comfy UI 7zip file from the official Website and extract it to a desired folder. Additionally, download the Comfy UI Manager for better usability.

Using Comfy UI Manager

Open the command prompt and access the custom nodes folder within the Comfy UI directory. Copy the URL of the Comfy UI Manager from its homepage and paste it into the command prompt using the git clone command. Run the NVIDIA GPU batch file to install and launch Comfy UI. Familiarize yourself with the interface, which consists of nodes and edges, representing a network or graph.

Creating a Graph for Image to Video Animation

Download an image from the Comfy UI examples page and drag it onto the Comfy UI web screen. This action will Create a graph for image to video animation. Select the stable video diffusion model for the image only checkpoint loader node. Choose the desired image from the input folder. Adjust the video frames to the desired value. Click on the cue prompt to generate the animation.

Changing Settings and Saving Video as MP4

Install the Comfy UI Video Helper Suite via Comfy UI Manager to enable the conversion of animation into an MP4 file. Add the video combine node to the graph and modify the settings according to the desired output. Connect the necessary links and click on the queue prompt to generate the MP4 file. The video will be saved in the output folder.

Creating a Graph for Text to Video Animation

Download an image from the video sample page and drop it onto the Comfy UI graph. Select the checkpoint for image generation and enter the desired prompt. Keep the default settings for other parameters or adjust them as desired. Select the stable video diffusion model for the image only checkpoint loader node. Configure the video settings and add the video combine node. Generate the animation using the cue prompt.

Generating Images with Improved Quality

To enhance the image quality, change the checkpoint to a desired version. Combine the capabilities of Facetailer, LoRA, and Stable Diffusion for superior results. Compare the animations created using different settings to observe the improvements.

Comparing Different Animations

Compare the animations generated from the image to video and text to video graphs. Observe the differences in image quality, frame rate, and visual elements. Evaluate the effectiveness of various models and settings in achieving the desired animations.

Using the Template Feature

Save a graph as a JSON file to easily recall it for future use. Create a folder named "template" within the Comfy UI directory and save the downloaded JSON file in it. By dragging and dropping this file onto the graph, you can swiftly access the saved graph configuration.

Conclusion

Comfy UI is a powerful tool for creating animations, offering impressive speed and efficiency. Although it may require some initial learning, the benefits of using Comfy UI outweigh the challenges. We encourage you to explore the possibilities of animation creation using Comfy UI and look forward to your creative endeavors.
