The WanImageToVideo node prepares conditioning and latent representations for video generation tasks. It creates an empty latent space for video generation and can optionally incorporate starting images and CLIP vision outputs to guide the video generation process. The node modifies both positive and negative conditioning inputs based on the provided image and vision data.
+**Output video frame rate:** The generated video uses a fixed frame rate of **16 FPS**. To calculate the output duration, divide the `length` (frame count) by 16. For example, the default length of 81 frames produces approximately 5 seconds of video.

+## How to Update ComfyUI Manager
+
+ComfyUI Manager is a custom node that provides installation and management of other custom nodes, models, and snapshots. It is separate from the ComfyUI core code and has its own update process.
+
+
+
+ The simplest way to update Manager is through its own interface:
+
+ 1. Open the **ComfyUI Manager** dialog by clicking the **Manager** button in the ComfyUI toolbar
+ 2. Go to the **Custom Nodes** tab (New UI) or the node list (Legacy UI)
+ 3. Find **ComfyUI-Manager** in the list and click the **Update** or **Install/Update** button
+ 4. Restart ComfyUI after the update completes
+
+
+
+ If you installed ComfyUI Manager manually via Git, update it with:
+
+ ```bash
+ cd custom_nodes/ComfyUI-Manager
+ git pull
+ ```
+
+ Then restart ComfyUI.
+
+
+
+ For the Windows Portable version, ComfyUI Manager is built into the core. Update it by updating ComfyUI itself using one of the update scripts in the `update/` folder, or through the Manager UI as described above.
+
+
+
+If the Manager is missing or disabled after an update, re-enable it via `--enable-manager` launch flag. See the [ComfyUI Manager Overview](/manager/overview) for details.
