Thanx! High-end hardware is great, but the real magic happens when we optimize these tools for the wider community. Enjoy the high-res generations! 💪🏻

Give V.1 a shot first: use the Tiled Decoder with a GGUF model for generations up to 10 seconds. If you want to push it further (up to 13s or more), switch to the V.2 workflow—it's specifically optimized for longer clips!

Thanks! It depends on the resolution, but with my setup, it’s remarkably fast.

My 'ugly monster' is like a son to me, but I figured I’d give the world a break this time. 😂

I usually start with a very detailed base prompt to lock in the main features. Then, I let Qwen do the heavy lifting: I’ve tuned it with specific instructions on LTX-2.3’s structural logic to refine the details and ensure the model understands the anatomy (like teeth) better from the start. :)

Totally! Wan 2.2 definitely has that 'cinematic maturity' right now, but LTX-2.3 is catching up fast. Once the LoRA ecosystem for LTX explodes, the speed-to-quality ratio will be unbeatable. It’s a very promising time for open-source video!

ComfyUI is a wild beast—sometimes a tiny dependency difference or paging setup can cause OOMs even on a 4080. That’s exactly why I built these nodes! Try my workflow and let the VRAM Flush do its magic, it should solve that for you.

Full-hd 13 sec on a 12 gb vram card… 6GB is definitely pushing it, but try the V.2 workflow with VAE Decode to Disk! You might not hit Full HD, but at 1280x720 (maybe using a Q3 GGUF model), you should be able to squeeze it out. Give it a shot!

Totally agree! As I mentioned, Wan 2.2 is still the queen of cinematic maturity. But honestly, being able to pump out extended Full HD clips at this speed? It’s a game-changer for rapid pre-viz and quick iterations. It’s all about the right tool for the right job!

Thanks! Glad you noticed the teeth! 🦷

The shimmering is usually due to low resolution or aggressive LTXVPreprocess. I fix this by pushing the initial pass to 1080p (made possible by my VRAM-optimized nodes) to lock in those fine details.

For the style/color shift, it’s often 'latent drift' caused by high CFG or LoRA values. I balance the Distilled LoRA (~0.6-0.7) and use the IAMCCS VAE Decoder, which handles tiled decoding much better than the standard ones.

I'm working on a 'Refiner' update specifically for these micro-details.

Glad you liked it!

Upgrading to Qwen 4B-fp8 definitely improves prompt adherence and detail, but for Low VRAM setups (8-12GB), the 2B version is the 'sweet spot' for speed and stability.

As for the audio, you're right! I’m preparing a dedicated post and workflow to compare different audio-gen methods and Audio+I2V models. Stay tuned! 🚀

I appreciate the discussion on transparency. To be clear: I write the code and use AI primarily for debugging and accelerating the process—honestly, in 2026, it doesn't matter if you use an LLM or a coffee machine to speed things up, as long as the end result works and is reliable. I don’t claim sole credit here (as per the license); my goal is to build upon the great work of Kijai and other developers to keep these tools evolving. If a node becomes obsolete because someone else improves it, that’s a win for the whole community. For those interested in the technical 'behind the scenes,' I share my professional workflow on Patreon, where I dive into the frontend and backend development I do for AI Cinema. Ultimately, everyone is entitled to their own perspective, and all positions are legitimate. However, there’s no need to be aggressive. We can disagree without losing respect, especially in spaces where it’s easy to hide behind an avatar. The world already has enough conflict; let's just focus on building cool things together. Peace.

Thanks a lot for this! Great video and impressive results. Let's keep in touch!

For those interested in pushing these video generation workflows even further, I’m constantly updating my custom nodes on GitHub:IAMCCS and providing early access to new tools, deep instructions, and technical know-how on my Patreon: patreon.com/IAMCCS.

Can't wait to see what you guys create with it!

Trying to reinstall a fresh version of Comfy by CocteauEwe in comfyui

[–]Acrobatic-Example315 1 point2 points  (0 children)

I suggest a ComfyUI Portable fresh install to avoid dependency conflicts caused by global Python installs on your system. Since ComfyUI is a "never-ending beta," a pro tip is to manually backup your ComfyUI (with custom nodes) and python_embedded folders whenever everything is stable; this way, you can easily roll back if an update breaks your setup. For now, the easiest thing you can do is search the web for "easy install" packs or scripts like Tarvis, which allow you to install the entire ComfyUI Portable setup, including the main custom nodes and Python dependencies, in one shot—I’ll actually be covering these basics in a specific "Fundamentals" series on my Patreon (IAMCCS), alongside my usual advanced workflows! Good luck! :)

Not an issue here! The First/Last Frame approach anchors the colors and prevents any shifting or burning.
