Inputs and outputs

Input: a video. Output: a video with the subject replaced.

Setup

It is listed as a workflow and uses Wan Video as its base model.

Dependencies

The listed node packs are comfyroll, comfyui_controlnet_aux, comfyui_essentials, comfyui_layerstyle, comfyui-kjnodes, comfyui-videohelpersuite, ComfyUI-WanVideoWrapper, and segment-anything-2.
The listed model files include flux/flux_vae.sft, flux/flux1-dev.sft, instantX-Flux-Union.safetensors, juggernautXL_juggXIByRundiffusion.safetensors, and sai_xl_depth_256lora.safetensors.
Other listed model files are sam2.1_hiera_large.safetensors, wan/Wan2_1_VACE_1_3B_preview_bf16.safetensors, wan/Wan2_1-T2V-1_3B_bf16.safetensors, and wan/wrapper_Wan2_1_VAE_fp32.safetensors.

Configuration

To move beyond the gray-background approach, consider adding depth, openpose, or inverted lineart.

DO NOT USE MASK BLURRING. VACE doesn't handle the blurring properly and you'll be left with artifacts

You can use any pre-processor you'd like, I'm using Depth here. DWPose, Canny, Lineart, all work as expected.

The flux group takes a lot of VRAM, if you are strugging with that, you can use SD15 or SDXL instead Flux model: https://huggingface.co/black-forest-labs/FLUX.1-dev Flux Clips (Text Encoders): https://huggingface.co/comfyanonymous/flux_text_encoders/tree/main For flux, make sure to download flux union controlnet. https://huggingface.co/Shakker-Labs/FLUX.1-dev-ControlNet-Union-Pro/tree/main If you want to use the SDXL controlnet, just make sure to switch the "controlnet image" node SDXL Model: https://civitai.com/models/133005/juggernaut-xl SDXL Controlnets: https://huggingface.co/lllyasviel/sd_control_collection/tree/main Put the controlnets in the models > controlnet folder
