Required custom nodes:

I also developed a custom node for transferring encoded latents between sections. This allows the encoded video and audio latents from the previous section to be passed directly to the next section, helping to avoid overcooking during continuation.

For the workflow to work, download the custom node archive and place the folder from the archive into the ComfyUI/custom_nodes/ folder.

You can download it from the drop-down list on this page. There is a separate archive for the workflows and a separate archive for the custom node.
