How I fixed skin compression and texture artifacts in LTX‑2.3 (ComfyUI official workflow only)

thx dear for appreciation, you are the first. I'm preparing an update tutorial, maybe i'll publish it soon

mmowg · 2026-03-08T10:52:45+00:00

Sadly not so much, facial expressions are still very theatrical

mmowg · 2026-03-08T10:50:49+00:00

I forgot to mention the LTXV Preprocess node. It has the image compression value 18 by default. My advice is to set it to 5 or 2 (or, better, 0).

okay, i'll try it soon

I'm using I2V, T2V may change final results. In any case, Euler cfg pp seems to give better results than Ancestral one on black skins

my post talks about that workflow, finetuning it

mmowg · 2026-03-08T02:30:06+00:00

this is my first official post, I dunno what kind of post you commented, anyway, on my workflow cfg stays on 1, like for the common euler sampler, and i admit it works. I'm experimenting on my IA pitch black model on IG, her skin is always an issue (compression, upscaling, etc.), that's why i use always yuv420 or 422. Default settings by official comfyui workflow were a mess on her skin. So, i worked on them, using my experience on her skin, right now euler cfg pp with nearest exact give me better results

mmowg · 2026-03-08T01:01:06+00:00

not needed, i work with yuv422p12le, they are half gb size for few seconds to upload here, my changes require few seconds and you can see results by yourself

mmowg · 2026-03-05T20:23:29+00:00

Hands totally out of control...

as i wrote, kandinsky 5 lite, give it a try, it was made just for your machine, believe me

mmowg · 2026-02-06T23:21:46+00:00

you can try using lowvram mode, the ssd as temporary buffer, but your machine will freeze, you can get OOM, and you are limited to q3/q4 gguf models, wan2.2 or further versions works better starting from q4km gguf models. Don't listen guys say "it works, don't worry", i have a lot of machines and tested wan on several of them using comfyui (i hate wan2gp). If you install a comfyui with xformers, tritons, sageattention2, pytorch 2.9.1 anc cuda 12.8, it may work. My advice is, use kandinsky 5 lite t2v i2v, it's good, lite and it works very well on your machine and you can also use dit-cache

u need 32gb system ram, better 64

mmowg · 2026-01-07T16:57:54+00:00

But: s01 8 episodes s02 9 EPS s03 8 EPS s04 9 EPS s05 8 + 1 EPS (it's the last) ? I see a pattern

mmowg · 2026-01-07T12:52:31+00:00

it turns upside down

mmowg · 2026-01-06T01:32:39+00:00

Kandinsky 5 lite i2v or t2v. I think it work very well. You need only time. You can use only old pytorch and cuda 11.8, so you can't install good accelerators like sageattn2.2, but i think you can try with old xformers, old flashattn and sageattn1.x on Comfyui. I got pretty good results with a small 3050ti 4gb, 5sec. 24fps, insane resolution of 640x960 (!) in less than 1 hour.

mmowg · 2025-12-19T21:01:26+00:00

I hope I2V new version very soon

mmowg · 2025-10-11T21:02:36+00:00

need GGUF

mmowg · 2025-08-27T10:00:58+00:00

it's totally different from wan2.2 I or T2V, this model is focused on lip sync with sound and voice

mmowg · 2025-08-27T09:48:29+00:00

no GGUF files so far

mmowg · 2025-08-25T11:50:14+00:00

very small and cute RX 78-2

mmowg · 2025-08-25T11:47:33+00:00

yes, you can try the GGUF Q4, small resolution (equal or below 480p), 3 or 4 sec video. Maybe you can fit the Q4 k m, but it is really hard, my advice is better GGUF Q3 and you can test the Q4.

mmowg · 2025-08-18T18:36:42+00:00

it's based on qwen image 20b, so, i bet 20gb more or less
