How to Create a Free 4K AI Lipsync Singer Video with ComfyUI

What the video teaches (tech overview)

• Goal: Create a free ultra-high-4K AI lip-sync “singer” video using ComfyUI.
• Core pipeline:
  1. Start with an open-source AI-generated image of a singer
  2. Use WanMultitalk to animate + lip-sync to music
  3. Render in ComfyUI, then upscale to 4K for high-quality output
  4. Optionally compile multiple takes in video editors (e.g., Premiere/CapCut)

Setup / Installation guide (ComfyUI + nodes/models)

1. Install ComfyUI (via the link shown in the video).
2. Install ComfyUI Manager, then update it in settings.
3. Load the provided workflow, check warnings, and download required models from links in the description.
4. Install missing nodes if the workflow indicates any.

Inputs you need

• Singer image:
  • Can come from online tools like GPT, Banana, Grok
  • Or open-source options like Flux, Qwen, Z-image
• Music track: the song you want the singer to perform.
• Reference motion video: used for camera movement simulation (cinematic feel), typically sourced from social media.

Workflow sections / key configurable features

Setting section

• Configure resolution + FPS
• Examples based on VRAM:
  • If VRAM < 16GB: max 1024×576, FPS 16
  • If VRAM ~24GB: can use 1280×720, FPS 25

Node Group 1

• Loads: singer image, reference motion video, music track
• Crops/trims the music to a 5–15 second singing segment

Node Group 2 (audio review/tuning)

• Reviews the trimmed audio
• Uses AudioSeparation to separate the singer’s vocal for later processing

Node Group 3

• Loads all required models

Node Group 4

• Encodes input info
• Lets you adjust a prompt to get “more vivid and expressive results”

Node Group 5

• Camera motion simulation driven by the reference video (zoom, pans, rotating camera, etc.)

Node Group 6: “Sampler and Decoce”

• Main generation step for the animated lip-sync output

Node Group 7

• Produces the initial HD output video

Upscaling to 4K (quality improvement)

• Node Group 8
  • Upscales HD → 4K using a model referred to as “Foolhardy”
  • Increases interpolation for smoother motion at FPS 30
• After this step, the workflow yields the final 4K video.
• Suggests generating multiple performance clips by repeating the process.

Post-production

• Combine multiple generated takes using Adobe Premiere or CapCut.

Reviews / results / tutorial framing

• The creator claims the style of video is “going viral on social media.”
• The tutorial emphasizes the process is completely free (assuming local setup via ComfyUI and downloaded models).

Main speakers / sources (as stated)

• Speaker/creator: The narrator of the video tutorial (no name given in subtitles).
• Tools/systems referenced:
  • ComfyUI
  • ComfyUI Manager
  • WanMultitalk
  • AudioSeparation
  • Foolhardy (upscaling model)
  • External image generators: GPT, Banana, Grok, Flux, Qwen, Z-image
