try to update your GGUF node, it's should solved it.

Also you are using a DEV version LTX-2 at the GGUF loader, but you have set to DISTLL at the dual clip loader. Not sure if it makes much of a difference, but worth a try ;-)
use the embedding_DEV model there instead ;-)

(or load a distill gguf if that was the intention)

Q2 is very small, your computer cant run the Q4 from here? https://huggingface.co/Kijai/LTXV2_comfy/tree/main (better if you can)

Load the new video VAE with VAELoaderKJ node, just like the audio VAE, not the usual vae loader from comfy core

i use gguf distill Q4 and vae loader kj,still got noise

I'm having the same problem. My gguf loader for LTX-2-dev-Q8_0.gguf worked fine until I updated to the latest build. Now it produces the same grainy red videos.

Tried here, to run GGUF to see if something was broken, but worked fine for me

I changed the flag --reserve-vram 6 back to --reserve-vram 4 and suddenly it works again and no more red videos. I have no earthly idea why this works or why 2 gb of vram would matter when I'm using a 5090

i got this when i get rid of -- pin memory in run_nvidia_gpu.bat
