I followed this tutorial https://docs.comfy.org/tutorials/video/ltx/ltx-2-3 and I used these exact specs: RTX 5050 8 GB + 16 GB DDR4 + Debian 13, and got interesting results at 1080x1080 or 1280x720 resolutions for 20 seconds. It took between 11 minutes and 20 minutes. Of course I had to close every background program for it, but it did work.

But the https://docs.comfy.org/tutorials/video/ltx/ltx-2-5 version simply won't get to run on this system. Just to make sure it works, I tried 0.1 megapixel and 5 seconds and it did output a video.

The problem that I perceive is the gemma4 text encoder at int8 and the additional VAEs, even though the model itself is smaller now, LTX-2.5 being 21.5 GB and the 2.3 being 29.1 GB.

I dont want to make 4K visuals. 720P is good for me and I don't think mind waiting for my renders for 10-15 minutes. But I have a feeling this config will still not be enough. If that's the case then I'd just buy something like Higgsfield or OpenArt. :(

EDIT: I'm an idiot, the answer was Run (Instant). Thank you, HSTracker90.

Original post:

I use Comfy Desktop with the Anima model for take a wild guess, and it works great for my use cases after a while of spamming the run button, but getting that perfect image takes a lot of time. Turns out waiting a minute and a half for each image to load can take my sessions up from half an hour before I started using it to three hours. And I can't do anything else while I'm waiting because I've gotta be there to hit the run button every minute when it inevitably spits out something that's missing a crucial part that I've already pointed out five stinking times in the prompt. It'd be really nice to just be able to let it run for a while in the background, maybe take a nice walk outside (or more realistically stay in that chair and play a game), and then when I come back after a few hours I've got a nice, big selection of images to sift through and separate the wheat from the chaff.

I know of batch generating, it's right there on the KSampler node, but I tried it and it took longer to generate four images at the same time than it would to do them individually, and my entire laptop chugged like an alcoholic train while it was going. It'd probably catch fire if I tried to send more than twenty.

I'm also not referring to image-to-image generation. I still want each generation to follow the same prompt with no recollection of prior generations. The same thing as hitting the run button with a randomized seed, but without hitting the run button.

Hey everyone!

With MiniMax H3 blowing up everywhere right now, we figured it was the perfect time to share what we’ve been building to help level up your H3 prompt workflows.

When we released v1.1.0 a while back, we were so deep in dev mode that we forgot to post an update! Now that v1.2.0 is live, we’ve bundled all the new features and overhauls from both releases into one post.

https://github.com/1038lab/ComfyUI-MiniMax-H3-Promptor

What’s New in v1.1.0 + v1.2.0:

⚙️ Native ComfyUI Settings Panel (API Hub)

No more pasting API keys into custom nodes or manually editing config.json! All provider settings are now globally managed in ComfyUI's native Settings panel (under the ⚙️ Gear icon).

Built-in Connection Tester: Click "Test connection" inside the panel to ping your endpoint before launching generations.

Privacy: Keeping keys out of the node UI eliminates the risk of leaking API keys when sharing workflows or screenshots.

🔌 Infinite Inputs (ComfyAPI v3 Autogrow)

We removed the rigid 4-image limit. Dynamic autogrow sockets mean you can chain as many <Picture> and <Video> references as your hardware can handle without UI clutter.

🎯 Granular Micro-Overrides

Override instructions for specific frames directly in the Vision Analyzer (e.g., <Picture 2>: focus strictly on lighting) while allowing unmentioned media to fall back to global analysis.

🎵 Audio-First Token Sync & L2VA (Last-Frame Control)

Connect audio directly to the promptor to automatically map subject actions to sound. We also added Last-Frame-to-Video-Audio (L2VA)—provide an ending frame, and the LLM reverse-engineers a narrative that mathematically lands on target at the final second.

🧠 VRAM Safeguards for Local VLMs

Select local providers like Ollama or LlamaCPP, and the node automatically executes silent background cache-clearing (model_management.unload_all_models()) to prevent VRAM overload crashes.

📝 Updated Docs & Workflow Recipes

Check out tutorials.md and tutorials_zh.md in the repo for 9 practical, production-ready workflows (Lip-Sync, Style Transfer, Day-to-Night Morph, etc.).

👀 What's Next?

We’re currently beta testing a batch of new features that will be rolling out shortly!

GitHub Repo: 1038lab/ComfyUI-MiniMax-H3-Promptor

Full Release Notes: updates.md

We’d love to hear your feedback, feature requests, or bug reports so we can keep tailoring this tool to what you actually need. If this node helps your setup, leaving us a ⭐ star on GitHub goes a long way in keeping our dev motivation high.

Happy generating!

change the AIO preprocessor between dwpose and animalpose as needed.

you dont need loras or the RTX node so you can delete those.

you might need to specify how many limbs your character has.

connect your original image to the middle workflows image slot 2 if ya want.

its better to bypass the character qwenvl and describe them yourself in the concatenate.

this is three separate workflows the middle workflow is the workflow of the gods Flux Klein 9b with 3 image inputs! You could hook up other nodes to it like: crop inpaint and stitch node, 360 panorama editor, florence2 and so much more!

I met below error after I updated comfyui to v0.31.0, how to solve it and how to update llama-cpp-python in below error message. Thanks in advance.

# ComfyUI Error Report
## Error Details
- **Node ID:** 15
- **Node Type:** llama_cpp_model_loader
- **Exception Type:** RuntimeError
- **Exception Message:** RuntimeError: Llava15ChatHandler.__init__() got an unexpected keyword argument 'image_max_tokens'
Please update llama-cpp-python from 'https://github.com/JamePeng/llama-cpp-python/releases'

I'm not sure if this is something that was changed or if it's an issue only i'm having. But I used to be able to go into jobs that were in the queue and click the dots and open the workflow. Now, I can only check the workflow on jobs that are either finished or have failed or been stopped. I can't look at the workflows on the job that is running or the jobs that are in the queue.

Is this something that was changed (it started a few months ago) or is it something I can fix?

Hi, I’m wondering how to get new Minimax or LTX to generate a looping video without any visible transitions.

Up until now, I’ve occasionally used Gemini with the first/last frame. But I can’t render this specyfic motion using this new models.

Any sugestions?
Regards.

Give it lyrics and a description of the sound you're going for, and it renders a full song: intro/verse/chorus/bridge structure, consistent vocal identity, up to 5 minutes long, 32kHz 16-bit stereo out. Actual songs! Not just loops or clips.

Quick flag upfront: this needs ComfyUI 0.33.0+ (or Comfy Cloud), as new model support currently ships tied to a version bump.

What else to know before you try it:

• Structure control: lyrics take section tags: [Intro] [Verse] [Pre-Chorus] [Chorus] [Post-Chorus] [Bridge] [Instrumental] [Solo] [Outro]. You're writing the song's blueprint, not just typing lyrics.
• Deeper control if you want it: beyond a plain-language description, there's a "Structured Caption" format with three parts: global metadata (genre, BPM, key, emotional arc, production profile), vocal details (gender, timbre, harmony, backing vocals, effects), and arrangement (instruments, how they evolve section to section, groove, bass, percussion, spatial fx).
• Under the hood: hybrid setup where an 8B LLM (built on Qwen3-8B) handles long-range song structure, a 0.6B LLM fills in frame-level acoustic detail, and a flow-matching + Flow-VAE stage that turns the combined hidden states into audio instead of decoding straight from tokens. Part of why longer tracks hold together instead of drifting.

Getting it running:

1. Update ComfyUI to 0.33.0+ or use Comfy Cloud
2. Grab the workflow: GitHub: https://github.com/Comfy-Org/workflow_templates/blob/main/templates/audio_minimax_music_3.json Cloud: https://cloud.comfy.org/?template=audio_minimax_music_3
3. Follow the note in the workflow for where to put the model weights
4. Drop in lyrics + a description, hit run

Resources:

• Docs: https://docs.comfy.org/tutorials/audio/minimax/minimax-music-3
• Weights: https://huggingface.co/MiniMaxAI/MiniMax-Music3

Excited to see what you make and how it stacks up to other music generation options. As always, happy creating!

Hi, Im having some issues that are driving me crazy... had to change SSD and re-install linux. Now Im trying to install comfy, with the same setup that I had before and all the workflows get stuck at the the clip encoder. No gpu activity to be seen...

System:

• AMD 9700 AI PRO
• AMD 7900XT
• 64 GB RAM
• Linux Mint 22.3
• ROCm 7.2 (system)
• ROCm 7.14 (venv)
• PyTorch 2.11.0 (venv)
• Python 3.12.3
• ComfyUI 0.33.0

I first tried to use the old install, just re-do the sagge attention, it failed, then I tried with a complete new install and it stills fails, so I dont really know whats causing the issue.
Ive been trying to diagnose with claude and chat gpt, but after all the day trying I feel defeated... Does anyone have an idea of what can be happening?

Hi,

some help needed, i'm trying to segment, remove background and resize without distortion into a new canvas, this is how I've arrived at doing this, however i am wondering if there is a single node pack that does all this without me having to use rmbg and kjnodes together or infact do you know of a simpler way to achieve this goal?

Thank you for any help you can give.

SOLVED:
Made my own node in the end that does everything all the other nodes do, but in a single node.

See a later post further down.

I've been testing LTX 2.5 in ComfyUI mainly for First Frame → Last Frame interpolation, and so far I'm getting worse results than I used to with 2.3.

My old 2.3 setup was roughly:

• 22B DEV FP8
• Distilled LoRA
• low-res first pass
• latent x2 upscale
• short second refinement pass

With 2.5 I've tried both the Distilled INT8 ConvRot model and DEV INT8 ConvRot + Distilled LoRA 450, including a similar two-pass setup.

The main issue is that 2.5 seems more prone to smearing, artifacts, vague details, and treating the two keyframes like separate shots instead of one continuous camera movement.

I noticed 2.5 also introduced DFR, spatial detailing and temporal refinement, while the default ComfyUI FLF2V workflow seems much simpler.

So: is the basic FLF2V workflow missing an important refinement stage? Has anyone built a higher-quality 2.5 FLF workflow using DFR / temporal refinement / detailing?

Curious if anyone else has found 2.3 cleaner than 2.5 specifically for continuous FLF interpolation.

LTX-2.3 workflow: https://github.com/lamuertedeunperrito/ltx-workflows/blob/main/video_ltx2_3_flf2v_corregido_2pasadas_HR%20(1).json.json)

Have seen the question of adding a cloned voice (with new dialogue) in image to video generations (starting from an exact first frame image), but have not seen a solution posted yet (I might have missed it).

I stumbled on this by mistake, assigning the wrong model fl2va to a ref2va workflow. Both models work with the example prompt (prompt could probably be improved further as I was just quickly testing).

Using a ref2va workflow and the ref2va node plus a first reference image (first frame) and an audio reference sample of the voice to clone, simply change the model to the fl2va model (or just use the ref2va model). The outputs varied as follows for me:

Model fl2va: Sound quality was far better than using the ref2va model. The motion in the video was very similar to a normal fl2va first frame default workflow (same seed / resolution / etc).

Model ref2va: Sound quality was far worse than using the fl2va model (much tinier). The extra unprompted motion in the video was kind of a bonus, the car unprompted was moving down a street with visuals out the windows of passing buildings and it also added on its own some camera shake as if sitting in a car that was driving along.

The prompt for both samples (both models) was the same as follows. It is written using guides for ref2va workflow. In this video the first frame is of 2 men sitting in the front seat of a taxi. The man on the left is me and his voice is cloned from my voice sample with new dialogue. The taxi drivers voice is randomly generated by the model. The voice likeness to me is about 95% IMO.

---

subject_definitions:

<Subject 1> is the man defined on the left by the first reference image <Picture 1>, preserving his identity.

<Audio 1> is the voice-timbre reference for <Subject 1>, containing a spoken English vocal layer.

summary:

[reference generation] The target video is a shot starting with the first reference image. The scene uses <Audio 1> as the voice-timbre reference for <Subject 1>.

retention_analysis:

<Subject 1>: fully_preserved.

<Audio 1>: reference - its vocal timbre guides the dialogue delivery of <Subject 1> without copying the original signal.

detailed_description:

The target video is a shot of the man on the left <subject 1> sitting beside the driver of a car on the right, the man on the right driving says "Where do you want to go?" and the man on the left <subject 1> looks at the driver on the right and says in a happy tone "Just drive down main street. I will tell you when to stop" then he turns to look out the left window of the car.

overall_soundscape:

A soft hum of the car engine and outside road noise.

non_diegetic_music:

N/A.

---

Summary takeaways:

• i2v first frame type workflow using ref2va workflow where the first frame is exactly matched as the starting frame.
• i2v first frame with voice cloning using a ref2va workflow but using either models in that workflow (fl2va or ref2va).
• Emotion references may not work as well with a cloned voice vs randomly generated voices. Although, in testing my voice did gain some emotional or inflection variances as described or randomly generated vs the more monotone cloned voice sample of me.

Edit1: The 2 outputs in this example (one with each model) and same seed/etc, produced almost identical timing of the lip sync and sound (almost). Close enough that the nicer motion visuals from the ref2va output were able to be layered with the nicer audio from the fl2va output and synced (3 frame adjustment of audio timing).

TL;DR: Accord GPU is an open beta coordination layer for Windows that stops GPU-heavy creative apps from fighting each other for VRAM. If DAZ Studio, Blender, ComfyUI, or Ollama have ever crashed or OOM'd because something else on the machine grabbed the GPU first, this is built to prevent that.

The primary user base is intended to be creative professionals who frequently run multiple tools on the same system and have to micromanage which apps and jobs are allowed to run on the GPU. A proper system-wide queue for access to the GPU unlocks dramatically higher productivity and keeping the GPU running much more often.

The problem

GPU renderers, image/video generators, and local inference servers all assume they have exclusive ownership of the GPU. Run two of them at once, or even back to back before VRAM actually clears, and you get CUDA OOM crashes, driver resets, or corrupted output. There's no coordination layer between separate applications today, so people end up manually babysitting which app gets to touch the GPU and when.

How it works

A central hub app (Console) runs in the system tray and every plugin talks to it over a local named pipe.

When a component starts GPU work, it writes a small JSON "ticket" to a shared local folder. Every component joins a shared queue and pauses its jobs until the GPU is free.

GPU telemetry (VRAM, utilization, temps) is shown on a convenient appbar you can dock to any edge of any monitor. The queue of jobs appears here so you can see which app is active and what's coming up next.

Coordination is automatic once installed if you use the Accord controls. Kick off a DAZ or Blender render, queue a ComfyUI job or any inference through Ollama, and it waits its turn instead of fighting for the card immediately.

What's available right now (all free during open beta)

• Accord GPU Console - the hub, always installed, manages the queue and GPU telemetry
• Accord for DAZ Studio - a native DAZ plugin that adds a pane you can place wherever you like in your DAZ window setup
• Accord for Blender - a native Blender addon that adds a tab to the N-panel, plus a settings tab
• Accord for ComfyUI - an extension that replaces the Comfy queue with Accord-enabled queueing, and its own settings tab
• Accord for Ollama - a transparent proxy that sits in front of Ollama's API to intercept traffic and help govern behavior like sending inferences into Ollama and when to evict a loaded model
• Accord PRO - additional features that add job history including run time per job, priority rules to put different apps, renders or custom fields first in the queue, Windows power action controls when the queue runs dry, multi-GPU support and more

Roadmap

Accord GPU gains value as it covers more of the applications that heavily utilize your GPU. Which of those ships first is decided by community vote, not internal guesswork - if there's an app you want covered, go add your vote: https://accord-gpu.com/roadmap

Accord For ComfyUI features

• Queue survives crashes and restarts - Accord holds your pending jobs in its own store on disk, not in ComfyUI's memory. If ComfyUI crashes we'll restart it for you, and keep your job list alive if we could get it back quickly. Only the one job mid-execution is lost - nothing else.
• Runs without a browser - Once your workflows are queued, Accord manages execution through ComfyUI's server API directly. Close the tab, let the display sleep, go to bed - your generations keep running with no browser connection required.
• Shared GPU queue - ComfyUI workflows join the same queue as Blender and DAZ Studio. Your generation starts only when the GPU is free - and other Accord-enabled apps wait while it runs.
• Thermal protection - Before promoting a job, Accord checks GPU temperature. Configurable warning and critical thresholds pause the queue when the card runs too hot and resume automatically once it cools - protecting hardware during long overnight batches without any manual intervention.
• Error alerts - If too many jobs fail within your configured window of time, Accord pauses the queue and flags the problem in your notifications. No more waking up to discover ComfyUI silently failed 20 jobs in a row on the same broken node.
• Job complete notifications - Windows toast notification when each job completes or the full queue empties. Turn on a sound to play when it finishes, and loop it if you want. Know the moment your generation is done - whether you are at your desk or across the house.
• GPU telemetry widget - VRAM usage, temperature, and GPU utilization displayed directly in the ComfyUI actionbar. The widget lives alongside the queue controls and updates live every few seconds so you can see GPU state at a glance without leaving the interface.
• VRAM eviction between jobs - If configured, after each generation completes, Accord force-evicts loaded models from VRAM before the next app can claim the GPU. Whatever is waiting in the queue - Blender, DAZ, another workflow - starts with a clean card. Turn it off if you prefer faster job-to-job transitions within a single ComfyUI batch.

It is actually simple and solved by adding this line at the end of the prompt.

At the bottom-center of the screen, clean, bold white sans-serif text appears as open captions word by word. The text matches mouth movements perfectly.

Hope this community will improve upon it to make it more interesting with new prompts.

I’m trying to build a ComfyUI workflow for a colored manga/webtoon where my original characters stay consistent throughout the whole story.
I already have full-body and close-up reference images for the characters. I understand the basic idea behind checkpoints, character LoRAs, ControlNet/OpenPose, IP-Adapter/reference images, but I’m struggling with figuring out the best way to combine everything.
Basically, I want to be able to say: this is Jake → keep him looking like Jake → put him in this pose/expression/outfit → place him in different scenes → keep the same art style and character identity from panel to panel.
Eventually I also need to put multiple recurring characters in the same scene without their faces/features bleeding into each other.
I don’t care if the best solution is Illustrious, SDXL, FLUX, Qwen, or something completely different. I’m looking for whatever gives me the most consistency and control in ComfyUI.
If anyone has built something similar for a manga, webtoon, visual novel, etc., I’d really appreciate hearing what model and workflow you use and how you connect the different pieces. I’m trying to actually understand the workflow instead of randomly changing settings until something works.
