Source description

Important credit for this workflow goes to pftq for creating the seamless video extend workflow . That workflow was the first to show me this feature existed and gave the building blocks I used to make this version. The workflow by pftq uses Kijai's Wan Wrapper nodes, so if you prefer to work with the wrapper nodes in order to make use of all the options and add-ons, then by all means give pftq's workflow a try. This workflow uses all native ComfyUI nodes for the Wan processing.

This I2V workflow is based on my earlier Wan Join Clips workflow. This simplified version is designed to extend a video using Wan with Vace based on a single beginning frame. Yes, I know Wan Image-to-Video already exists, but the results you get from using the Vace system can be quite different, so I think this is a useful tool.

The workflow looks large, but once you've made sure all your models are loading correctly and your video save paths are set the way you like, you should only need to use the three groups across the top-left. You set your initial image (and reference image, if you like), you set other values like steps and so on, then you run the workflow and check your output. All of the masking, resizing, and frame interpolation/smoothing is automated.

AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.

Purpose

Use Wan Vace Image-to-Video to extend a video with Wan and Vace from a single beginning frame. Provide an initial image, an optional reference image, and settings such as steps; the workflow produces an extended video.

Flow

Masking, resizing, and frame interpolation or smoothing are handled automatically after you set the inputs.
Additional controls are exposed in other groups for further adjustment.

Inputs and outputs

Inputs include an initial image, an optional reference image, settings such as steps, and video save paths; the output is an extended video.

Setup

Before running, make sure the models load correctly and set your video save paths.
