Single-node wrapper for Bernini video editing in ComfyUI. Handles text encoding, VAE encoding of source video and reference images, and context_latent construction in one node instead of wiring 5+ separate nodes.
Built-in Ollama/vLLM prompt enhancement using Bernini's official per-task templates with optional vision (sends your reference images to the LLM for accurate descriptions).
This is a personal tool shared as-is. Vibedcoded boucing ideas and code between Claude Opus 4.6max & Gemini 3.1pro. No guarantees/support/maintenance commitment - Is what it is
- ComfyUI with Bernini model support via Kijai's PR #14216 or equivalent
- Bernini model weights from HuggingFace or Kijai's FP8 repacks
Clone into ComfyUI/custom_nodes/:
cd ComfyUI/custom_nodes
git clone https://github.com/CCpt5/ComfyUI-BerniniStudio.git
The input slots are named image0 through image7. Use the same names in your prompt text:
Replace the man with the old man from image0
Not reference_image_0, not source_video, not the person in image0. The trained format is "from image0".
Fill slots in order starting from image0. If you skip slots (e.g. only connect image6), it gets compacted to image0 internally. The slot number only matches the prompt marker if you fill sequentially.
The source video is implicit -- don't name it in your prompt. Just describe what's in the video naturally.
The dropdown selects a system prompt and configures the hint panel. It does not change any model behavior -- the actual "mode" comes from what you wire and how you set up the sampler.
| Mode | What it does | Wire | Guidance |
|---|---|---|---|
| v2v | General video edit | source_video | v2v_apg |
| rv2v | Edit guided by reference image | source_video + image0 | rv2v |
| r2v | Generate video from reference subject | image0 | r2v_apg |
| t2v | Text to video | nothing | t2v_apg |
| mv2v | Change motion/pose | source_video | v2v_apg |
| ads2v | Insert logo/ad into scene | source_video + image0 | v2v_apg |
| i2i | Image editing | source_video (1 frame) | v2v |
| r2i | Image from reference subject | image0 | r2v_apg |
| i2v | Animate a reference image | image0 | r2v_apg |
Collapsible panel in the node. Supports Ollama and OpenAI-compatible endpoints (vLLM, LiteLLM). Uses Bernini's official prompt templates from their repo.
With a vision-capable model (llava, gemma4, etc.), connected reference images are automatically fetched from LoadImage nodes and sent to the LLM as base64. Works through intermediate nodes (Resize, Preview, etc.) -- the graph is traced backwards to find the original LoadImage.
Auto-enhance checkbox runs the enhancement server-side on every queue. Enhanced text is logged to the ComfyUI console (not the browser). The prompt field in the node may not visually update but the enhanced version is what gets encoded.
