Anyone else only getting noise as their output?

All I get no matter what I tweak.

I have Cuda 12.6 and 12.8 and the same for either (Linux and Windows). Not sure how they ended up releasing this like this, so I figured it was something on me. From the first moment this has be a very problematic release. From their WFs having everything as node connection I had to bring back to widgets (every single node was like this even the VHS nodes in their workflow) which took a while, to having other issues with a ticket I closed after I got it to work that I had to ask if it was just me. Others seem to not have this issue, so I wonder if it is their workflow and using it is why we get this stuff, while others are using non stock workflows and it works?

on the fp8 version, yes, 100% of the time I get noise

on the full version, no, it works as expected

Noise on 3090

Damn, as I have the fp8 model. Guess this is now a dead project until we get a gguf version.

ltxv-13b-i2v-base workflow does work with full model ltxv-13b-0.9.7-dev.safetensors

ltxv-13b-i2v-base-fp8 workflow does not work (noisy output, as mentioned from OP) but I was not able to build the Q8 kernels for the LTXQ8Patch node for my portable ComfyUI version before ... did you guys suscessfully installed the LTXVideo-Q8-Kernels package?

ltxv-13b-i2v-base workflow does work with full model ltxv-13b-0.9.7-dev.safetensors - this is what i have, and no, didnt work -> noise output.

full or fp8 same nonsense? :( I spent a day in hell down a deep rabbit hole to fix a few nodes. I got everything to work BUT this thing. I gave up. For the other nodes I had to delete venv and start clean over. What a pain, but after hours I got them to work unlike this thing.

This is because when you use fp8 version, you cannot skip the q8_kernel node, otherwise you will get this, also make sure you are on cuda 12.8 when you install q8 kernel!!

Their pack so are you saying they released BS? Yes, that is exactly what you are saying as they rushed it out.

Thanks.
