ComfyUI V145 ChangeLogs

24 October 2026 Update V145

Presets Folder Content In Latest Zip File

This is a MiniMax H3 Genjutsu update. V145 adds two Genjutsu presets that replace the person in any video with your own character: add your clip and one image of the new character, press Run, and the result keeps the clip's motion, timing, camera, length, aspect ratio and original sound. One preset uses FastH3 Omni at 8 steps, the other MiniMax H3 Ref2VA at 20 steps. V145 also adds a Genjutsu section to the MiniMax H3 prompt guide and brings the new Genjutsu nodes of our FoleyExtension.

Our test: this armoured warrior image and a 9.8-second phone clip of a man shadowboxing in a gym. Both new presets put the warrior into the clip, punch for punch and step for step, in the clip's portrait format and with its own sound:

Every result in this post comes from a real run of the shipped presets in ComfyUI started with our Windows_Run_ComfyUI_Default.bat: each preset was opened from the Workflows sidebar and run with the Run button, with its shipped settings and the example it opens with. The times are ComfyUI's times on our RTX 5090 for a first run, model loading included. We ran both presets again on the newest ComfyUI that the installer installs today and got the same videos, frame for frame.

Exact V144 → V145 zip audit:

• 2 new files: the two MiniMax H3 Genjutsu presets.

• 1 changed file: the MiniMax H3 prompt guide, with the new Genjutsu section.

• No files were removed. The other 238 files are identical. The Genjutsu nodes arrive through Windows_Install_Or_Update_ComfyUI.bat, which installs our updated FoleyExtension.

Here is the complete Presets folder of V145: 108 ready-to-use ComfyUI presets, plus 3 API presets in the api_paid folder. The two new presets are marked NEW:

The presets cover image, video, lip sync, audio and music models: AvatarForever, ERNIE Image, FastH3 Omni, Fibo 2.0, FLUX.1 Dev, Kontext and SRPO, FLUX 2, FLUX 3 Klein, Ideogram 4, Krea 2, LTX 2, LTX 2.3, LTX 2.5, MiniMax H3 (now with Genjutsu), MiniMax Music 3, MOSS-Image and MOSS Image Edit, Phantom Wan, Qwen Image, SDXL, Stable Video Infinity 2 Pro, Wan 2.1, Wan 2.2 and Z-Image.

NEW PRESETS — MINIMAX H3 GENJUTSU: PUT YOUR CHARACTER INTO ANY VIDEO

"MiniMax H3 Genjutsu - FastH3 Omni 8 Steps - 261024"
"MiniMax H3 Genjutsu - Ref2VA 20 Steps - 261024"

How it works: SAM 3.1 finds the person in every frame of your clip, and only that person is colour-inverted. MiniMax H3 then copies the clip's motion, timing, camera and lip movements, but not the performer's face, hair or clothes. A local Qwen3-VL 8B (Auto Describe) looks at your character image and six frames of the clip and writes the prompt for you: the new outfit, the action, the setting, the lighting and the framing. The clip's soundtrack is locked into MiniMax H3's audio stream for lip sync, and the saved video carries the original sound.

• Your inputs: the clip as @video1 and one image of the new character as @image1, added with Add references or Load + trim (to pick the part of the clip you want; 4 to 10 seconds works best, up to 15). The presets open with our example loaded; if those example files are not on your PC, remove the two cards and add your own.

• The output follows the clip: the same length, the same aspect ratio at about 1 megapixel, and the original sound. Our 9.8-second 1080x1920 clip gave 226 frames (9.4 seconds) at 768x1344.

• Prompt: keep the short default note, type your own notes (for example "He wears his red scarf."), empty it, or paste a complete MiniMax H3 prompt from ChatGPT, Claude or Gemini; a complete prompt is used as written.

• Background: video keeps the clip's location, lighting and framing and replaces only the performer (character replacement); image keeps your character image's background and takes only the motion (motion transfer).

• Target: who to replace, in plain words: person, or man in red:1 to pick one of several people.

• Speed: FastH3 Omni 8 steps made the 9.4-second example in 4.4 minutes and Ref2VA 20 steps in 8.3 to 9.4 minutes, first runs with model loading on an RTX 5090.

Here is the FastH3 Omni preset right after the run of our example, with every part numbered:

After a run, CHECK THE MASK shows the performer in red in every frame, MOTION GUIDE shows what MiniMax H3 copies the motion from, and FINAL PROMPT SENT TO H3 shows the prompt Auto Describe wrote. The token meter under the prompt now follows Genjutsu too: it shows the clip's length and aspect ratio before you press Run.

UPDATED PROMPT GUIDE — MINIMAX H3 GENJUTSU

The MiniMax H3 guide in Automatic_Prompt_Generate_Enhance_To_Video_And_Image_Models_LLM_Instructions has a new Genjutsu section. Give it to an LLM that can watch video (for example Gemini) together with your clip and your character image, and paste its answer into the prompt box. It can write the exact spoken words for word-by-word lip sync.

HOW TO UPDATE

1. Download the latest ComfyUI_V145.zip from this post.

2. Extract it over your existing installer folder and overwrite the older files.

3. Close ComfyUI, and SwarmUI too if it uses this ComfyUI as its backend, then run Windows_Install_Or_Update_ComfyUI.bat. It updates ComfyUI and installs our FoleyExtension with the Genjutsu nodes.

4. If you have not done it since V144, run Windows_Custom_Nodes_Bundles_Installer.bat and install/update bundle 100.

5. Restart ComfyUI and refresh the browser tab.

Use our latest SwarmUI Model Downloader (SwarmUI_Model_Downloader_v185.zip or newer) and download the bundle from the SwarmUI Bundles tab:

• FastH3 Omni Core Bundle (60.12 GB, 11 files) for the FastH3 Omni Genjutsu preset, or the MiniMax-H3 Core Bundle (79.91 GB, 19 files) for the Ref2VA 20 steps preset. Both now include SAM 3.1 (1.63 GB) and Qwen3-VL 8B INT8 (8.71 GB, the same file as the Qwen Image 2.1 encoder, so you do not download it twice), sizes as the downloader shows them.

• If your ComfyUI reads your SwarmUI Models folder through extra_model_paths.yaml, ComfyUI uses the files downloaded there without a second download.

SwarmUI V185 Logs

24 October 2026 Update V185

This is a MiniMax H3 Genjutsu update. V185 adds two presets that replace the person in any video with your own character: attach your clip and one image of the new character, press Generate, and the result keeps the clip's motion, timing, camera, length, aspect ratio and original sound. Our MiniMaxH3References extension gets the new MiniMax H3 Genjutsu group, and the model downloader adds SAM 3.1 and Qwen3-VL 8B to the MiniMax H3 and FastH3 Omni bundles.

Amazing SwarmUI Presets moves to V84 with 86 presets: the two new presets, and the other 84 presets unchanged.

Our test in SwarmUI: this armoured warrior image and a 9.8-second phone clip of a man shadowboxing in a gym. Both presets put the warrior into the clip, punch for punch and step for step, in the clip's portrait format and with its own sound:

Exact V184 → V185 zip audit:

• Presets: Amazing_SwarmUI_Presets_v83.json was replaced by Amazing_SwarmUI_Presets_v84.json. Its 84 presets are unchanged in every setting, description and thumbnail; 2 presets are new.

• 6 changed files: the model catalog and its size data (SAM 3.1 and Qwen3-VL 8B in the MiniMax-H3 Core, MiniMax-H3 Low VRAM and FastH3 Omni Core bundles), update_swarmui.py (a premium extension that could not be replaced during an update is installed again by the next update), the downloader app (shows v185), the regenerated Which_Bundles_Downloads_Which_Preset_Models.html and the MiniMax H3 prompt guide (new Genjutsu section).

NEW PRESETS — MINIMAX H3 GENJUTSU: PUT YOUR CHARACTER INTO ANY VIDEO

"MiniMax H3 Genjutsu - FastH3 Omni 8 Steps - 261024"
"MiniMax H3 Genjutsu - Ref2VA 20 Steps - 261024"

How it works: SAM 3.1 finds the person in every frame of your clip, and only that person is colour-inverted. MiniMax H3 then copies the clip's motion, timing, camera and lip movements, but not the performer's face, hair or clothes. A local Qwen3-VL 8B (Auto Describe) looks at your character image and six frames of the clip and writes the prompt for you: the new outfit, the action, the setting, the lighting and the framing. The clip's soundtrack is locked into MiniMax H3's audio stream for lip sync, and the saved video carries the original sound.

Where to find it: Quick Tools → Reset Params to Default, then the Presets tab → type Genjutsu in the filter → the preset card's menu → Direct Apply. Attach the clip and the character image with Add References (or Add A Reference With Trim to pick the part of the clip) and press Generate. Here is the FastH3 Omni preset after a real run of our example:

• MiniMax H3 Genjutsu (on): turns the first reference video into the SAM 3.1 motion guide.

• Genjutsu Background: video (character replacement) keeps the clip's location, lighting and framing; image (motion transfer) keeps your character image's background and takes only the motion.

• Genjutsu Target: who to replace, in plain words: person, or man in red:1 to pick one of several people.

• Genjutsu Auto Describe (on): the local Qwen3-VL 8B writes the outfit, action, setting, lighting and framing into the prompt. Leave the prompt empty, type short notes, or paste a complete MiniMax H3 prompt from ChatGPT, Claude or Gemini; a complete prompt is used as written.

• Genjutsu Spoken Words (optional): the words spoken in the clip, for word-by-word lip sync.

• Genjutsu Lock Clip Audio (on) and Genjutsu Match Clip Aspect (on): the clip's sound drives the lip movements, and the output takes the clip's aspect ratio at your Width x Height area.

• Genjutsu Motion Guide Megapixels (0.15): the guide size; advanced options set the detection threshold and the mask grow.

• The output follows the clip: our 9.8-second 1080x1920 clip gave 226 frames (9.4 seconds) at 768x1344, and the token meter beside the prompt shows that length and size before you press Generate.

• Speed: FastH3 Omni 8 steps made the 9.4-second example in 4.5 minutes and Ref2VA 20 steps in 9.9 minutes in SwarmUI, first runs with model loading on an RTX 5090.

MODEL DOWNLOADER — SAM 3.1 AND QWEN3-VL 8B IN THE MINIMAX H3 BUNDLES

The MiniMax-H3 Core Bundle, the MiniMax-H3 Low VRAM Bundle and the FastH3 Omni Core Bundle now download everything the Genjutsu presets use:

• SAM 3.1 Multiplex FP16 (1.63 GB, saved to Models/Stable-Diffusion): finds the person to replace in every frame.

• Qwen3-VL 8B INT8 ConvRot (8.71 GB, saved to Models/text_encoders): writes the Genjutsu prompt. It is the same file as the Qwen Image 2.1 encoder, so if you already have it, the downloader checks it and keeps it.

• New totals: MiniMax-H3 Core Bundle 79.91 GB (19 files), MiniMax-H3 Low VRAM Bundle 64.21 GB (19 files), FastH3 Omni Core Bundle 60.12 GB (11 files), sizes as the downloader shows them.

HOW TO UPDATE

1. Download SwarmUI_Model_Downloader_v185.zip from this post and extract it over your existing downloader folder.

2. Close SwarmUI and run Windows_Install_or_Update_SwarmUI.bat. It installs MiniMaxH3References 1.22.1 and our FoleyExtension with the Genjutsu nodes.

3. Keep the ComfyUI backend up to date. If SwarmUI uses our ComfyUI installation, close SwarmUI again (step 2 starts it, and a running backend blocks the update) and update that ComfyUI with our ComfyUI installer V145 (Windows_Install_Or_Update_ComfyUI.bat), which also brings the same Genjutsu presets to ComfyUI. If SwarmUI uses its own ComfyUI, open Server → Backends, edit the ComfyUI Self-Starting backend and set AutoUpdate to Always Update for one start.

4. Restart SwarmUI and its ComfyUI backend so the new extension and nodes register.

5. With SwarmUI running, run Windows_Preset_Delete_Import.bat to import Amazing_SwarmUI_Presets_v84.json. It backs up your current presets, thumbnails included, to utilities\presets_backups, deletes them all (your own presets too) and imports the new pack.

6. Run Windows_Start_Download_Models_App.bat and download the MiniMax-H3 Core Bundle or the FastH3 Omni Core Bundle (the files you already have are checked and kept).
