Purpose

  • This ComfyUI MMAudio workflow is for adding realistic audio to AI video: it takes a video path, loads MMAudio features and models, samples and previews audio, and provides a video-combine output stage.

Flow

  • The stages cover video loading and video information, MMAudio feature and model loading, audio sampling, audio preview, and video combining.

Inputs and outputs

  • VHS_LoadVideoPath loads the video path, and VHS_VideoInfo provides video information.

  • MMAudioFeatureUtilsLoader and MMAudioModelLoader load features and models, while MMAudioSampler samples audio.

  • PreviewAudio previews the audio, and VHS_VideoCombine provides the video-combine output stage.

Setup

  • The workflow is published on Civitai by Lordcaocao2025 at https://civitai.com/models/2367459.

Dependencies

  • The model files are apple_DFN5B-CLIP-ViT-H-14-384_fp16.safetensors, mmaudio_large_44k_v2_fp16.safetensors, mmaudio_synchformer_fp16.safetensors, and mmaudio_vae_44k_fp16.safetensors.

  • The node packs are comfyui-mmaudio and comfyui-videohelpersuite.

Cautions

  • Before use, confirm that all four model files and both node packs are available.
