Zip file that includes everything with full changelogs shared here :

26 August 2026 Update V131

  • When you touch the prompt box, it was becoming shrinked and this issue resolved
  • MiniMax H3 Upgrades
    • Continue videos using the final 1, 5, 22, 39, or 56 frames, instead of only the last frame.
    • Multi-frame continuation uses MiniMax H3’s native clip guide for stronger motion, identity, and scene continuity.
    • Replayed context frames and matching audio are automatically removed from the generated segment before merging.
    • Continuation works with both FL2VA and Ref2VA without consuming an additional reference-image slot.
    • The two Image To Video presets are now Image or Video To Video.
    • So with these presets now you can do image to video or video to video

  • Start Frame / Init Video now accepts images or videos. A video can supply its final frame or selected multi-frame context.
  • Merge videos can append the new generation directly to the uploaded source video, preserving video order and audio.
  • Folder batches retain sequential generation, per-prompt saves, continuation, and final merged outputs.

  • Now we have contextual continue feature with Continue From Last Video Frames option we have

  • This feature implemented into SwarmUI as well so read it too
  • To update : get latest zip file, extract and overwrite all, then run Windows_Install_Or_Update_ComfyUI.bat and also Windows_Custom_Nodes_Bundles_Installer.bat (bundle 100) - all necessary custom nodes and extensions automatically installed and many of them managed by us for extra security

22 August 2026 Update V129

  • Python 3.10 not anymore supported because onnxruntime-gpu 1.27+ CUDA 13 build requires Python 3.11 or newer
    • The installer will auto delete your existing Python 3.10 venv and auto generate new Python 3.12 venv if you have Python 3.12
    • Please have Python 3.12 and use it
  • This is a very big update : 8 new official LTX 2.5 presets, MiniMax H3 Init Audio (make the video follow any soundtrack with lipsync), live token meter, Face Inpainting upgrades, automatic FL2VA / Ref2VA routing, a speed update and a big installer overhaul so please read all
  • 8 new LTX 2.5 presets added

  • The 2-stage presets generate at 960x544 with 8 distilled steps, then apply the official LTX 2.5 latent spatial upscaler x2 and run 3 more refinement steps on a 1920x1088 canvas, and finally center crop to exact 1920x1080 - all with synchronized audio at 24 FPS and about 5 seconds by default
  • The Fast preset stays single stage at 960x544 for quick tests, and the First Last Frame preset is the official single-stage 1280x720 workflow : load a first and a last image and it generates the connected shots in between
  • The Expert preset exposes every stage on the canvas (Preprocess, Generate stage 1, Upscale and re-sampler stage 2, tiled Decode) with notes explaining each setting - the Text To Video and Image To Video presets are the compact subgraph versions, enter the subgraph when you want to fine tune

  • Audio To Video : load any audio, trim it with audio start and duration, and the video is generated to follow it (lipsync, action timing) - the encoded audio tokens stay frozen in both stages and your original trimmed audio is muxed into the output untouched, never decoded from latents - an optional start image is supported

  • Motion Track Control : drag points on the LTX Sparse Track Editor to sketch how things should move on your start image, and the motion track IC-LoRA animates exactly along those paths - a tracks preview video is saved next to the result so you can check the motion before committing to a long run

  • Text To Audio : audio only generation (sound effects, ambience, music cues) with the same LTX 2.5 model - no video VAE and no upscaler needed in this flow
  • Prompt enhancement (the official Gemma 4 E2B INT8 ConvRot enhancer) is off by default in every preset - enable it to expand short prompts into rich cinematic ones - and entering an LTX API key switches text encoding to the API to save VRAM
  • Models : one bundle for everything - open the latest model downloader and grab the LTX 2.5 Video Core Bundle : it now contains every model referenced by all ten of these LTX 2.5 presets : https://www.patreon.com/posts/114517862

  • LTX2.5 IC LoRA Pixel Spatial Upscaler presets fixed (FAST Distilled and Slower HQ) : the 4 helper nodes they need (LTX-2.5 Upscale Controls, Distilled Sigma Schedule, Prepare Video Chunks, Merge Video Chunks) are now part of our auto installed and managed by us extensions
  • Both upscaler presets also switched from the 24.46 GB BF16 text encoder to the 14.32 GB Gemma 4 12B INT8 ConvRot v2 one, so all ten LTX 2.5 presets now share the exact same text encoder and prompt enhancer - that is 10 GB less to download and one less model kept in memory when you switch between presets
  • New LTX2.5_Enchance_Prompt_Feed_For_LLMs.txt inside the Prompt_Generate_MiniMax_LTX_and_Demo_Materials folder : an official-aligned LTX 2.5 prompting guide for LLMs - give it to ChatGPT / Claude / Gemini, tell it what you want, and it writes properly formatted LTX 2.5 prompts for text / image / audio to video, multi-shot and IC-LoRA workflows
  • Optional Init Audio added to all six MiniMax H3 video presets (Text To Video, Image To Video, References To Video - both 8 Steps and 4x Speed) : select or upload any audio - or even a video file - in the new INIT AUDIO (OPTIONAL) node and the generated video follows that soundtrack exactly : lipsync, action timing, ambience - and keeps it as the exact final audio track

  • Leave it at (none - disabled) and the presets work exactly as before
  • Works with text only prompts, start frame and gallery references - by default the video duration automatically follows the audio length or set duration_mode to keep workflow duration
  • Init audio accepts video files with a visual trim panel - drag the handles to pick exactly which part of the soundtrack to use, nothing is re-encoded
  • Folder batches : put a same-name audio / video file next to each batch item and it is automatically used as that item's init audio (SAME-NAME INIT MEDIA)
  • Live MiniMax H3 token meter added to the reference gallery : prompt + references + resolution + duration are counted in real time against the 109k token budget so you see the usage before you queue - the meter also follows your init audio selection and trim window

  • Automatic FL2VA / Ref2VA routing : the MiniMax H3 video presets now pick the right checkpoint per prompt by themselves - single runs that have references and every folder batch item go through the Auto FL2VA / Ref2VA pipeline while plain text prompts keep the normal path - and the References To Video presets got an optional INIT IMAGE node : FL2VA uses it as the exact first frame, Ref2VA adds it as the starting frame picture reference (folder batch items ignore it and keep using their same-name init media and last frame continuation)

  • Face Inpainting upgrades : new faces to inpaint widget selects which faces get refined : 1 = biggest face (default), 2 = second biggest, 1,3 or all - faces are ranked biggest to smallest and each selected face is refined in its own pass and tagged in the tracking preview
  • New hallucination guard : every regenerated face crop is compared against its input and frames where H3 painted a neighbouring or different face over your subject are not pasted
  • Geometry lock is further improved and ON by default - removes the per-frame face shaking / tilting that the face pass could introduce
  • MiniMax H3 Text With References To Image preset also received the new face inpaint subgraph and a randomized seed

  • Speed : MiniMax H3 Sol-Attn sparse attention updated for SM89 (RTX 4000 series) and CUTLASS 4.7 in our maintained ComfyUI-TeaCache fork
  • Example on RTX 5090 : 1344x768 10 second video dropped from 450 seconds to 401 seconds with the updated speed optimizer
  • FLUX 2 Klein presets switched to my new INT8 ConvRot HQ models - almost BF16 quality but massively faster - auto download them with the latest model downloader : https://www.patreon.com/posts/114517862

  • Installer overhaul : custom nodes are now updated in-place instead of delete and re-clone so files downloaded inside node folders (for example ckpts) survive updates - a fresh clone replaces a node only when the in-place update fails
  • Leftovers of interrupted installer runs are cleaned automatically and staged copies use .disabled names so ComfyUI never imports duplicate nodes
  • Deleted venv is recreated in place without re-cloning ComfyUI - your models, outputs and user data are never touched - and the installer window now always stays open with a clear final status message
  • Python 3.10 support dropped because onnxruntime-gpu 1.27+ CUDA 13 build requires Python 3.11 or newer : menu now offers 3.11 / 3.12 (recommended) / 3.13
  • OpenCV conflicts between custom nodes fixed for good : all four OpenCV distributions are kept at one resolved version and opencv-contrib-python-headless is reinstalled last then verified - RES4LYF, controlnet_aux, Frame-Interpolation and rembg each pull different ones
  • onnxruntime-gpu upgraded to 1.27+ (CUDA runtime used by FantasyPortrait) and google-genai added to requirements
  • ComfyUI-Frame-Interpolation now installs without CuPy - it is not needed by the bundled RIFE workflows
  • RunPod and Massed Compute installers received the same in-place update and OpenCV normalization treatment
  • Windows_Run_GPU.bat renamed to Windows_Run_ComfyUI_Default.bat
  • To update : get latest zip file, extract and overwrite all, then run Windows_Install_Or_Update_ComfyUI.bat and also Windows_Custom_Nodes_Bundles_Installer.bat (bundle 100) - all necessary custom nodes and extensions automatically installed and many of them managed by us for extra security

16 August 2026 Update V122

  • Presets and custom nodes updated to improve face shaking effect that happens when automatic face inpainting activated
  • All presets now do have live preview (no increase in VRAM or generation duration) and fixed seed feature

16 August 2026 Update V120

  • I have added automatic Face Inpainting feature to all MiniMax H3 presets
  • Get latest zip file, extract and overwrite all and run installer update bat file to update
  • Also use updated extra_model_paths.yaml if you are downloading models into SwarmUI

14 August 2026 Update V117

  • Since you have requested, all MiniMax H3 presets modified and easy LoRA use added
    • If you don't select any LoRA, workflow works just fine no issues so they don't break presets and how they work, they are optional

  • 3 New presets added
    • MiniMax Music 3 Text To Music - 260813.json - New model published today
    • LTX2.5 IC LoRA Pixel Spatial Upscaler 2x - FAST Distilled 8 Steps - 260813.json
    • LTX2.5 IC LoRA Pixel Spatial Upscaler 2x - Slower HQ - 260812.json

  • Moreover, I have converted the LTX 2.5 Int8 ConvRot myself higher quality and more accurate than officially published ones
    • Someone detected one of the model is corrupt and broken - officially released ConvRot Int8 variant
    • I converted them from BF16 versions after big research and experimentation
    • So our model downloader app will download better quality Int8 ConvRot of LTX 2.5 models
  • Our Musubi Trainer convert to quant tab also now supporting LTX 2.5 Int8 ConvRot compile : https://www.patreon.com/SECourses/posts/secourses-musubi-137551634
  • LTX 2.5 video generation presets and bundles will be added soon hopefully but its quality lower than MiniMax H3
  • Get latest zip file, extract and overwrite all, then run Windows_Install_Or_Update_ComfyUI.bat and Windows_Custom_Nodes_Bundles_Installer.bat (select bundle 100) for updating all

12 August 2026 Update v116

  • To improve security, I have forked auto installed repos and bundle 100 repos and now they will be installed from secure fork
    • Only few repos left as exception which are famous : mcmonkeyprojects , kijai , Lightricks
    • I also did a massive deep security check of all auto installed and bundle 100 repos source codes and all are secure
  • MiniMax H3 presets got updated and now we have new features
  • Now when batch processing, you can dynamically set the duration of each prompt
    • It will split the file name of the prompts with _ and if last split is a valid integer, it will be used as the duration of the prompt, otherwise whatever you set will be used
    • Folder durations now use the final positive integer suffix only when the filename contains *: scene*7.txt → 7s; 200.txt, scene.txt, and scene_0.txt use the configured duration
    • For example scene1.txt or 1.txt will use your set duration on the workflow meanwhile scene_1.txt will be set to 1 second duration dynamically
  • Added Continue from last frame beside Merge, disabled by default

  • Continuation automatically uses Ref2VA when references exist and FL2VA otherwise
  • Updated all MiniMax presets, extension UI, documentation, and the LLM prompt feed
    • MiniMax_H3_Enchance_Prompt_Feed_For_LLMs.txt improved big time and includes latest changes and features as well
  • The most professional speed up LoRA maker LightX2V just published new speed LoRAs for the MiniMax H3

  • Our MiniMax H3 core bundles now auto downloads both FL2VA Turbo 8-step v1.0 and FL2VA Turbo 4-step v1.0 768p
  • All presets by default uses FL2VA Turbo 8-step v1.0 but you can switch it to FL2VA Turbo 4-step v1.0 768p
  • Older version 0.1 removed from downloads and presets so you can delete from LoRA folder if you downloaded
  • All presets exposes Shift value for Video and Audio seperately now
    • So you can set to 6 / 3 if you switch to FL2VA Turbo 4-step v1.0 768p - default is 12 / 3
  • Sadly LoRAs only made for non-reference model atm but works on both models until they publish specific new LoRA for reference model
  • Some people asked me if video-latent continuation input is possible or not and sadly not possible so your best option is using continue from last frame
  • Get latest zip file, extract and overwrite all, then run Windows_Install_Or_Update_ComfyUI.bat and Windows_Custom_Nodes_Bundles_Installer.bat (select bundle 100) for updating all

11 August 2026 Update v113

  • RunPod and Massed Compute startup command changed so that the running ComfyUI instance won't be accessible by public IP anymore
    • Updated files are : Massed_Compute_Instructions_READ.txt and RunPod_SimplePod_ComfyUI_Instructions_READ.txt
    • Windows doesn't have such vulnerability it is fully locally running
  • Use Cloudflared secure HTTPs to access publicly when you are running on cloud services
    • RunPod and Massed Compute installers auto installs Cloudflare
    • Follow Massed_Compute_Instructions_READ.txt and RunPod_SimplePod_ComfyUI_Instructions_READ.txt
    • Public access is optional, it will be default fully locally restricted running
  • When using unicode character containing references it was causing issues
    • For example an image with Ü Ğ characters, this issue fixed and now works
  • Just run Windows_Install_Or_Update_ComfyUI.bat to update and always get latest zip file and overwrite older files
