ComfyUI native support SkyReels-V1-Hunyan-I2V basic workflow - v1.0 - A ComfyUI workflow for image-to-video generation using SkyReels-V1-Hunyan-I2V model

## Primary Function of the Workflow The primary function of the workflow is **image-to-video generation** using the SkyReels-V1-Hunyan-I2V model. It supports high-resolution (544×960) output at 24fps for up to 4 seconds of video. ## Key Features of SkyReels-V1-Hunyan-I2V The model features include: - **Advanced facial animation**: Captures 33 facial expressions and 400+ natural motion combinations. - **Cinematic quality**: Trained on Hollywood-grade film/TV data for professional lighting and composition. - **Human-centric realism**: Optimized for lifelike motion and spatial relationships. ## Installation Requirements To use the workflow, users must: 1. Install **ComfyUI** and required nodes (e.g., KJNodes, VideoHelperSuite). 2. Download the **SkyReels-V1-Hunyan-I2V model** and VAE files from Hugging Face. 3. Place model files in ComfyUI’s `models/diffusion_models` and `models/vae` directories. ## Hardware Recommendations A minimum of **24GB VRAM** is recommended. For lower VRAM, users can reduce frame count or use quantized models. ## Comparison with KJ Workflows Unlike KJ workflows (which may rely on custom nodes), this workflow emphasizes **native ComfyUI integration** for simplicity. It prioritizes cinematic output over extended customization options. ## Resource Locations - **Workflow download**: [Civitai](https://civitai.com/models/1270433/basic-workflow-for-comfyui-native-support-of-skyreels-v1-hunyan-i2v) - **Model files**: [Hugging Face](https://huggingface.co/Kijai/SkyReels-V1-Hunyan_comfy) ## Workflow License The workflow operates under the **Tencent Hunyan Community License Agreement**. ## Troubleshooting Output Quality Users should: - Adjust **prompt words** and parameters. - Verify correct model/VAE file placement. - Reduce resolution/frame count if VRAM is insufficient. ### Citation sources: - [ComfyUI native support SkyReels-V1-Hunyan-I2V basic workflow - v1.0](https://civitai.com/models/1270433/basic-workflow-for-comfyui-native-support-of-skyreels-v1-hunyan-i2v) - Official URL Updated: 2025-04-01
