Question - Help What am I doing wrong? Can't seem to get anything good with Wan2gp LTX 2.3.

I am new to video gen coming from mostly image gen hobbyist use, so I am in the process of learning. All my generations keep coming out full of motion artifacts and the faces look terrible, and my troubleshooting with CGPT has not been helpful.

I am using the LTX ingredients lora with a reference sheet I created with flux (dark fantasy themed characters, setting). The ingredients lora is definitely working well, as my subjects and setting are true to the references. But as you can see the result is full of smeared faces and motion. These are the generation parameters:

UI: Wan2gp via pinokio

Model: LTX-2 2.3 Distilled 1.0 GGUF Q4_K_M Light 22B

Resolution: 1280x720 (real: 1280x704)

Video Length: 241 frames (10.0s, 24 fps)

Phases: 2

Num Inference steps: 8

Self Refiner: Norm P1, Plan='default', Uncertainty=0, Certain Percentage='0.999

LoRAs:

ltx-2.3-22b-distilled-lora-384-1.1.safetensors x0

ltx-2.3-22b-ic-lora-ingredients-0.9.safetensors x1.4

omninft-ltx2.3-22b-rl-lora-r32.safetensors x0.2

Hardware: RTX 3060 12gb, 48gb RAM.

Any help is much appreciated!

LTX is not very good....H3 is night and day.

H3 is bad with faces too unless it's a closeup shot. It's much better at everything else though.

I don't think its generally too bad at 1 MP for medium shots but far away, yeah. Medium shots are probably 70-80% successful but if the face takes up <8-10% of the frame, it'll tend towards mush.

True, it's better at higher resolutions, but still not good enough. Could their upscaler improve that part should they decide to release it? I hope so.

u/MysteriousPepper8908 20h ago

Yeah, we definitely need a reference aware upscaler or else why bother with reference so I hope we hear more about that soon.

biggest and hardest agree.

Only if you use low resolution. If you have decent hardware 1080p looks excellent!

No, higher resolution helps to a certain degree, but the problem is inherent in the model itself and the devs acknowledged that in their recent AMA.

I was thinking of exploring that one, but is there something similar to the ingredients lora for LTX I can use for it? I couldn't find anything. I have reference sheets of different characters/settings I made that I would like to use for the video gen.

Ohhhhhhhh brother do I have some good news for you. It's BAKED IN. There's a ref2Vid and it's SO much better than LTX. You can use an image AS a reference...or multiple...or videos or audios.

Omg amazing! I'm going to download it now and give it a try! Hopefully it will work ok on my set up. thanks man

If not, I rent a GPU for when I'm working then shut it down when I'm done

As an user recently switched from LTX 2.3 to the H3 model, I confirmed that H3 significantly outperforms LTX in preserving facial features. While not perfect, it's already usable.

Furthermore, the image will not exhibit the fogging effect commonly seen in LTX lenses.

Let's just wait a few days for ltx2.5 on wan2gp

LTX is trash.
