+
+**Wan2.1 InfiniteTalk** is an open-source audio-driven video generation model built on Wan2.1, developed by [MeiGen-AI](https://github.com/MeiGen-AI/InfiniteTalk). It enables you to generate full-body talking videos from a single reference image and an audio input. The character's mouth movements and body motions are automatically synchronized to match the provided audio.
+
+**Key Features**:
+- **Audio-Driven Lip Sync**: Generate natural mouth movements that match the input audio
+- **Full-Body Motion**: Preserves identity, background, and camera movement while adding synchronized body motion
+- **Dual Mode**: Supports both single-character and multi-character scenarios
+- **ComfyUI Native**: Built-in `WanInfiniteTalkToVideo` node, no custom nodes required

+### Sample Input Files
+
+Download these sample input files and drag them into the corresponding nodes:

+
+## Workflow Steps
+
+1. **Load the input image**: Drag the character reference image to the `Load Image` node. For multi-character scenarios, use the Mask Editor to draw masks for each character.
+2. **Load audio tracks**: Connect audio files to the `Load Audio` nodes (one per character).
+3. **Load diffusion model**: Ensure the `Load Diffusion Model` node is using `Wan2_1-I2V-14B-480p_fp8_e4m3fn_scaled_KJ.safetensors`.
+4. **Load model patches**: Load the appropriate InfiniteTalk patch (`single` or `multi` variant) via the `ModelPatchLoader` node.
+5. **Configure InfiniteTalk**: Adjust the `WanInfiniteTalkToVideo` node parameters (video length, motion amount, etc.).
+6. **Generate**: Run the workflow. The model will produce a full-body talking video synchronized with the input audio.
+
+### Extending Video Length
+
+Each **Video Extend** group extends the video by approximately 3.24 seconds (81 frames at 25 fps). If your audio is longer, you can:
+
+1. Box-select the "Video Extend" group
+2. Press `Ctrl-C` (copy), then `Ctrl-Shift-V` (paste with connections)
+3. Connect the `Batch Images` node's `IMAGE` output to the new `WanInfiniteTalkToVideo` node's `previous_frames`
+4. Connect the `Batch Images` node's `IMAGE` output to the new `Batch Images` node's `images`
+5. Adjust the connection between the previous group's `WanInfiniteTalkToVideo` output and the new group's `VAEDecode` input
