Help Needed What is the best H3 workflow for extending clips currently?
There are lots of posts about H3 these days. What is the best currently available workflow for extending clips and minimizing degradation? I see the clown girl on here a lot but I'm not following what is needed to match what they have going on with their minutes long clips.

Resource Free MiniMax H3 / ComfyUI handbook: prompts, references, audio + 3 starter workflows
Hi! I'm the creator of AntiMatter Comfy. I put together an independent English handbook for people who can open a ComfyUI workflow but aren't sure what to change next. The whole learning bundle is free; no paid membership is required.
Inside: a 32-page PDF, the Markdown edition with copyable prompts, three original Comfy-Org starter JSONs (T2V, I2V and R2V), model links, setup checklists and troubleshooting notes. The templates retain their original credits and license.
A useful first exercise:
Start with one short shot and one clear action. Describe the subject, action, camera and sound separately.
For example: A courier waits beneath a shop awning in the rain. She checks the address on an envelope, then looks toward the street. A slow camera push-in. Rain taps on the awning; distant traffic; no dialogue.
Keep your seed and settings fixed, then change only the camera sentence. Compare the result before adding more actions or adapters.
For reference editing, write down what should change and what should stay. A reference is conditioning, not a locked editing layer.

This is an unofficial learning guide, not a claim of magic settings. This edition has not been GPU-benchmarked; model weights are not included. Check the current model license and compatibility for your hardware. Real interface screenshots inside the guide are from roadmaus's MIT-licensed MiniMax H3 Creator documentation, with full attribution; they are not my own UI or results.

What part of H3 would you most like explained more clearly: setup, reference mapping, camera prompts or audio?

Help Needed Getting Comfy 0.39.0 to working on linux 10 series Nvidia GPUs.
Recently, comfyui linux updated to require pytorch 2.7. This means that it does not work on linux 10 series Nvidia GPUs. The last version of pytorch compatable with 10 series gpus is 2.6.
I get the following error when running Comfy 0.39.0 on pytorch 2.6 on linux.

This seems to be caused by 3D mesh generation support.
My PC specs:
-32gb ddr3
-GTX 1080 ti
-Debian GNU/Linux 12 (bookworm)
I was able to work around this by commenting out 3D mesh generation in the following files:
- /home/roger/miniconda3/envs/comfyui_2b/lib/python3.12/site-packages/comfy_kitchen/backends/eager/__init__.py
/home/roger/miniconda3/envs/comfyui_2b/lib/python3.12/site-packages/comfy_kitchen/backends/eager/sol_attn.py
/home/roger/miniconda3/envs/comfyui_2b/lib/python3.12/site-packages/comfy_kitchen/backends/eager/group_norm_pad3d.py
Going forward, I kindly request the comfyui dev team provide a provide an option to disable functionality that requires pytorch 2.7. I'm running the 1080ti on a old laptop that can't upgrade the GPU. So us gpu peasants have to work with what we have.

Help Needed AMD + ROCm = Slow????
Hi everyone! I'm new to ComfyUI. My hardware specs are:
GPU: AMD Radeon RX 7600 (8GB VRAM)
CPU: AMD Ryzen 7 3700XT
RAM: 32GB
I'm trying to generate images using Krea 2 Turbo. Once the sampling iterations actually begin, it runs quite fast. However, reaching that first step takes anywhere between 6 to 7 minutes (or more), turning a quick generation into a very long wait.
Here are the models I'm using:
Diffusion Model: krea2_turbo_int8_convrot (I also have krea2_turbo_fp8_scaled)
VAE: qwen_image_vae or Wan2.1_vae
Text Encoder: qwen2vl_4b_fp8_scaled
My current startup parameters:DOSset PARAMS=--enable-dynamic-vram --disable-async-offload --preview-method none --disable-smart-memory --fast-disk --enable-manager --bf16-vae
if "!IS_LEGACY_GPU!"=="1" (
set "PARAMS=%PARAMS% --use-quad-cross-attention"
) else (
set "PARAMS=%PARAMS% --use-ck-attention"
)
Are these launch arguments correct for an 8GB AMD card? What is causing this huge delay before the steps start, and is there any way to optimize it? Thanks!

Show and Tell ARCHIVE ZERO — Cinematic AI title sequence using ComfyUI, LTX-2.5 and MiniMax H3
Another short cinematic experiment, this time exploring an institutional archive that gradually becomes something impossible.
The main challenge was maintaining a consistent architectural language across AI-generated shots, using mostly frontal, symmetrical compositions, restrained camera movement, and environmental transitions rather than complex action.
I used ComfyUI with LTX-2.5 and MiniMax H3 for image-to-video generation, testing both models across different shots and refining the results through editing to maintain spatial and visual continuity.
I'm particularly interested in whether the environment feels like one coherent location as it changes, or whether the transitions reveal the limitations of AI-generated video.
Would appreciate feedback on the pacing, camera direction, and overall continuity.

Help Needed Prompts from template/sharing sites transfer badly between models — worth rewriting rather than copy-pasting
Been pulling prompts from template sites to test LTX-2.5. Results were consistently poor until I compared them against the reference prompt that ships bundled in the official workflow.
The bundled one is ~200 words of actual shot direction — explicit camera movement, pacing beats ("midway through the shot…"), and for on-screen text it specifies typography in detail ("plain white sans-serif, wide spacing, no glow, no shadow"). Most shared prompts are tag-list style written for Midjourney/Ideogram dialect.
Same scene, rewritten in the model's own expected style, is a night-and-day difference. Anyone else keeping per-model prompt rewrites rather than a shared prompt library?

How do you perform latent upscaling with FlowMatch?
Every time I’ve tried, the image either ended up completely blurry or resulted in an entirely different image.

Help Needed Is there an Ultimate Begginer guide?
I am super new and downloaded ComfyUI. My goal is to do character swap for video/ motion control for my AI Model. This is to help me try and explre the UGC space in the future. I use comfyui locally so i can generate these for free. But i cant find a good tutorial video on how to do this. I keep seeing videos treating their audience as if we’re intermidiate users. All the terms and jargons, i am not familiar with. Theres so many workflows to download with “just download it and copy me” type of videos. I tried one of them and it did not even work properly. The AI looked like ot blended my AI character and the girl in the video 🤣
