# ComfyUI Custom Resolution I2V (v1.1) A specialized resolution utility node for **WanVideo Image-to-Video (I2V)** workflows. This node provides standard resolution presets while offering a manual override system with automatic compatibility rounding. --- ## ✨ What's New in v1.1 - **Expanded Aspect Ratios:** Now supports **16:9** and **9:16** specifically for cinematic and mobile formats. - **Variable Framerates:** Choose between **16, 24, or 30 fps** to suit different motion styles. - **Simplified Manual Override:** Removed manual rounding selection; the node now automatically rounds dimensions to the nearest multiple of 8 for maximum encoder compatibility. - **Improved UI:** Updated tooltips and display names for better clarity within the ComfyUI interface. --- ## 🛠 Installation ### Option 1: Via ComfyUI Manager (Recommended) 1. Search for `Custom Resolution I2V` in the ComfyUI Manager. 2. Click **Install**. 3. Restart ComfyUI. ### Option 2: Manual Installation (Git) 1. Open a terminal in your `ComfyUI/custom_nodes/` folder. 2. Run the following command: ```bash git clone [https://github.com/AugustusLXIII/ComfyUI_CustomResolution_I2V.git](https://github.com/AugustusLXIII/ComfyUI_CustomResolution_I2V.git) 3. Restart ComfyUI. --- ## 🚀 How to Use ### 1. Aspect Ratio Choose between: * **Portrait (2:3 or 9:16)** * **Landscape (3:2 or 16:9)** * **Square** ### 2. Resolution Level Select a preset tier (**k18 to k55**). These are optimized according to the WanVideo specification. The node automatically calculates the correct width and height based on your chosen aspect ratio. ### 3. Manual Override * **Enabled:** The node uses `manual_width` and `manual_height`. * **Automatic Rounding:** Your custom dimensions are automatically rounded to the nearest multiple of 8. This prevents "invalid shape" errors during video encoding. * **Fallback:** If either dimension is set to 0, the node defaults back to the selected Preset Level. ### 4. Framerate & Duration * **Framerate:** Select **16**, **24**, or **30** FPS. * **Video Duration:** Set the total length in seconds (1.0 to 10.0). --- ## 📦 Node Outputs - **width/height:** The calculated integer dimensions. - **length:** Total frame count (calculated as `Duration × FPS + 1`). - **framerate:** The selected FPS as a float. --- ## 📄 License This project is licensed under the MIT License.
