README

ComfyUI-H3-Continuum 3.9.8 — V3.9

Generate long-form MiniMax H3 video and audio in chunks, review each result, retry a section, and continue from compatible saved Takes. V3.9 is the current workflow; V3.8X2 remains available separately.

Getting started video

Watch: H3 Continuum V3.9 — Chunks, Prompts & Reference Images — 12:26, with English narration, subtitles and chapters.

The video covers First Image setup, chunk settings, Review/Take retries, Timeline prompts and Reference Images. For screenshots and every control, open the illustrated user guide.

Install or update

Use one Continuum installation in ComfyUI/custom_nodes. Models and third-party custom nodes are not bundled.

Fixed-version ZIP

Download the custom-node ZIP above and optionally verify its checksum.
Extract its package folder into ComfyUI/custom_nodes. When updating, replace the existing package; do not leave duplicate copies.
Restart ComfyUI and hard-refresh the browser (Ctrl+F5).
Open a V3.9 workflow below and select your installed models and input files.

Keep your saved workflows, Run/Take folders and settings when updating. Workflow ZIPs contain graphs, not the custom-node installer.

Git or ComfyUI-Manager

For a new Git installation:

cd ComfyUI/custom_nodes
git clone https://github.com/ukr8b3g-cmyk/ComfyUI-H3-Continuum.git

For an existing Git installation:

cd ComfyUI/custom_nodes/ComfyUI-H3-Continuum
git pull --ff-only origin main

If Manager owns your installation, update that copy through Manager. Restart ComfyUI and refresh the browser after updating. Registry review, Manager's selected version and GitHub Releases are separate; the fixed-version links above identify the exact v3.9.8 package.

The package declares Python 3.10+ and ComfyUI 0.32.0+. The minimum declaration is not a GPU acceptance result for every Core version.

Required model files and extensions

Download the weights separately from Comfy-Org / MiniMax-H3. The table follows the saved V3.9 template selections; folders are relative to ComfyUI/.

Component	File / download	Folder
H3 diffusion model	minimax_h3_fl2va_pruned_int8_convrot.safetensors	`models/diffusion_models/`
Text encoder	qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors	`models/text_encoders/`
Video VAE	minimax_h3_video_vae_int8_convrot.safetensors	`models/vae/`
Audio VAE	minimax_h3_audio_vae_fp32.safetensors	`models/vae/`

Select the downloaded files in the loaders; set the text encoder's type to minimax. Reselect paths if the saved minimax/ subfolder differs from your installation. The Video VAE loader selects INT8, although its older embedded download metadata names FP16; choose the VAE you actually installed. Other model variants must match the generation task and loader support. Quantized variants require compatible Core/GPU support; these selections are not a universal hardware guarantee. The r
