For the latest Bernini Director (multi-segment timeline), please migrate to AIMixer/ComfyUI_Bernini_Director.
We have switched fully to the official ComfyUI Bernini-R stack (native
VAE/MODEL/CLIP,context_latents, dual-stageKSamplerAdvanced; see PR #14216). Compared with the legacy wrapper pipeline in this repo, the official path is generally more stable, better optimized, and faster in real runs, and it tracks ComfyUI core improvements automatically.All future maintenance and feature work will land only on the official-path project. This repository remains available as a historical reference.

最新版 Bernini 导演台（多段时间轴）请迁移至 AIMixer/ComfyUI_Bernini_Director。
我们已全面改用 ComfyUI 官方 Bernini-R 技术路径 （原生
VAE/MODEL/CLIP、context_latents、双阶段KSamplerAdvanced； 详见 PR #14216）。 相较本仓库的独立 wrapper 旧链路，官方路径通常更稳定、优化更完善、实际运行也更快， 并能随 ComfyUI 核心一并获得持续改进。后续功能与修复将全部基于官方技术路径维护，仅在新仓库发布。 本仓库仅保留作历史参考。
Standalone ComfyUI plugin with a complete Wan 2.2 Bernini pipeline that does not depend on ComfyUI core Bernini nodes (PR #14216).
中文文档 → README_ZH.md
Quick start
-
Clone into
ComfyUI/custom_nodes/:cd ComfyUI/custom_nodes git clone https://github.com/AIMixer/ComfyUI-Bernini.git -
Install Python dependencies (use the same Python environment as your ComfyUI):
cd ComfyUI-Bernini pip install -r requirements.txtOn Windows portable builds, prefer ComfyUI's bundled Python, for example:
..\..\python_embeded\python.exe -m pip install -r requirements.txt -
Restart ComfyUI. Nodes appear under the Bernini category.
-
Download models — quantized GGUF / FP8 + workflows: comfyit.cn/article/489; original Kijai FP8 only: HuggingFace Bernini. Put weights under
ComfyUI/models/(diffusion_models/,vae/,text_encoders/). See Quantized models. -
Run a workflow: Model Loader → Context Embeds → Sampler → Decode. Example JSON workflows: Comfyit article 489.
Quantized models
Download: Comfyit article 489 — Bernini models & workflows (GGUF quantizations, scaled FP8, VAE, T5, and example JSON).
Wan 2.2 Bernini diffusion weights are available in GGUF and FP8 safetensors quantizations. Place files under ComfyUI/models/diffusion_models/ and load both HIGH and LOW in Bernini Model Loader (GGUF is supported).
| Tier | GGUF (LOW / HIGH) | Min VRAM (Bernini Director) |
|---|---|---|
| Q4_K_M (lowest) | Wan22_Bernini_LOW-Q4_K_M.gguf · Wan22_Bernini_HIGH-Q4_K_M.gguf | 8 GB |
| Q5_K_M | Wan22_Bernini_LOW-Q5_K_M.gguf · Wan22_Bernini_HIGH-Q5_K_M.gguf | 10 GB |
| Q6_K | Wan22_Bernini_LOW-Q6_K.gguf · Wan22_Bernini_HIGH-Q6_K.gguf | 12 GB |
| Q8_0 | Wan22_Bernini_LOW-Q8_0.gguf · Wan22_Bernini_HIGH-Q8_0.gguf | 16 GB |
FP8 safetensors (scaled, same naming as Kijai Bernini pack):
Wan22_Bernini_LOW_fp8_e4m3fn_scaled.safetensorsWan22_Bernini_HIGH_fp8_e4m3fn_scaled.safetensors
VRAM tips (Bernini Director, HIGH + LOW): Q4 → 8 GB min; Q5 → 10 GB; Q6 → 12 GB; Q8 → 16 GB. Enable Block Swap on both loaders; use T5 disk cache or fp8 text encoder where possible.
All quantized builds above are included in the resource pack at comfyit.cn/article/489. For the original non-GGUF FP8 pack from Kijai, see HuggingFace.

Bernini Director (KJ backend)
All-in-one node with an embedded timeline editor: upload video and reference images inside the node, split segments, set per-segment prompts / task_type, then run the full Bernini HIGH/LOW pipeline in one queue. Uses Bernini Model Loader (GGUF + Block Swap) for lower VRAM.
Example workflows: see Example workflows below (all from Comfyit article 489).
Bernini Director Official (ComfyUI core backend)
Same timeline UI as Bernini Director, but execution goes through ComfyUI native Bernini (VAELoader / UNETLoader$ \times 2 / $CLIPLoader → BerniniConditioning → dual-stage KSamplerAdvanced), aligned with PR #14216.
| KJ Director | Official Director | |
|---|---|---|
| Models | Bernini Model Loader (GGUF) | UNETLoader fp8_scaled |
| Text | Bernini Text Encode Cached | CLIPLoader (wan) |
| VRAM | ~8 GB with Q4 GGUF | Higher; use --lowvram, CLIP on CPU |
Typical v2v workflow: load bernini_director_official_core_v2v_2.json → connect VAE / UNET×2 / CLIP → upload source video → Equal Split into segments → global prompt → queue once, export all segments.
