Configuring Mocha Embeds in ComfyUI

ComfyUITry it →Watch full video →SOTAISOTAI·

Demo summary

The creator demonstrates how to set up the Mocha Embeds node in ComfyUI, connecting the VAE model, reference video, first-frame mask, and character reference images.

Step-by-step

  1. Locate the Mocha Embeds node
  2. Connect your VAE model to the VAE input
  3. Feed your reference video as a sequence of images into the input video slot
  4. Provide a mask for the first frame of the video in the mask input
  5. Input the character image for replacement into the reference 1 slot
  6. Connect the generated image embeds from the Mocha node into the one video sampler node

Options

  • Connect a detailed face reference to the reference 2 input to help maintain facial consistency
  • Skip the reference 2 input if desired

Watch out for

  • The node requires a mask for the first frame to define the object being replaced

Tips

  • Unlike other workflows, you only need to provide a mask for the first frame rather than every frame
  • The reference 2 input can be skipped as testing shows the difference in facial consistency is not significant in this workflow

Highlights

“Once that's done, everything else becomes super straightforward.”
