Wan 2.2 Light2X Image-to-Video
ComfyUI Workflow: Wan 2.2 Light2X Image-to-Video This ComfyUI workflow utilizes Wan 2.2 and the Light2X Lora to efficiently generate video from images. It focuses on rapid production and flexible output, enabling users to create dynamic clips with optimized performance. What makes this workflow efficient * **Fast Generation**: Produce videos in as few as 4 steps, significantly reducing processing time. * **Multi-Dimensional Output**: Supports various video resolutions including 480p, 720p, and custom sizes. * **High Frame Rate**: Generates 32 frames per second videos directly through integrated interpolation using FILM VFI. * **Optimized Model Loading**: Employs FP8 models to accelerate the generation process, leading directly to sampling. * **Streamlined Lora Management**: The RGTHREE Power Lora Loader allows for loading multiple loras without requiring numerous nodes. Generation speed highlights * A 5-second 480x832 video can be generated in approximately 1 minute 10 seconds after an initial run. * A 5-second 720x1280 video can be generated in about 3 minutes 30 seconds after an initial run. * This efficiency supports generating multiple short videos quickly. How to use this workflow * **Model Loading**: The workflow uses both High noise and Low noise Wan 2.2 models. FP8 models are advised for faster processing. * **Lora Integration**: Use the RGTHREE Power Lora Loader. Set the high_noise_model loader at strength 2 and the low_noise_model loader at strength 1. For other loras, load the same lora file into both loaders, with the first loader at double strength. * **VAE and Clip**: Always use the Wan 2.1 VAE. FP8 is recommended for Clip for balance between speed and quality. * **Image and Prompt**: Load your source image and select desired output dimensions. Input your text prompt and specify video length (e.g., 81 frames for 5 seconds, 160 frames for 10 seconds). * **Sampling**: Two KSamplers are utilized, one for each noise model. Light2X enables generation in just 4 steps. Euler / Simple or Euler / beta are recommended samplers. Keep CFG at 1 to maintain quality and avoid artifacts. * **Video Assembly**: The initial video output is at 16fps, which is then interpolated by FILM VFI to achieve a final 32fps video. Lora usage guidance * Wan 2.2 Loras are highly recommended, requiring both High and Low noise models from their respective Civitai pages. * Wan 2.1 Loras are compatible. Load the same lora file in both loaders, with the first (High noise) loader set at double the strength of the second. This workflow offers a streamlined and efficient method for creating high-quality, high-framerate videos from images within ComfyUI.
This ComfyUI workflow uses Wan 2.2 and the Light2X Lora to quickly generate 32 FPS videos from a single image in 4 steps. It supports various dimensions, leverages FP8 models for speed, and includes a multi-Loras loader. Generation involves high and low noise models, a Wan 2.1 VAE, FP8 CLIP, and a KSampler with a CFG of 1. Users input an image, a text prompt, and specify video length, with specific Lora loading instructions for optimal results.
